Annotated Game #330: A flexible Stonewall and a false fortress

In this last-round tournament game, I follow an independent line of the Colle and end up in a Stonewall formation with White, which I am normally comfortable playing. However, as has often happened in past games, I accept (and choose) too many cramping versus freeing alternatives, and end up in a worse position. This was no fault of the Stonewall, which can in fact be flexible; see moves 14-18 for some examples in the analysis. In the end, I was lucky that both myself and my opponent believed I had successfully closed the position to further progress, which was not in fact the case, although there was no immediate knockout.

Annotated Game #329: A Caro-Kann gambit revalidated

This next tournament game saw me as Black equalize early, in one of the very few Caro-Kann gambit lines (Advance Variation with 3...c5). My Expert-level opponent was clearly unfamiliar with this line, which sacrifices a pawn but allows Black dynamic compensation or to regain the material. White, despite some reasonable-looking moves, lost the initiative early and then allowed a tactic which gave me a winning (but not won) position. There was plenty of play left, but the main inflection point was on move 20, where calculation exhaustion led to sub-par results for me in both the calculation and evaluation process. The trajectory of the game continued downwards after that, despite some other chances for me to regain a major advantage.

Despite the loss, the parts of the game where I did play well helped re-validate the opening choice and my knowledge of how to press an advantage. As often occurs in hindsight, playing more simply and with more clarity than complexity would have given me a better game.

Training quote of the day #57: Mikhail Shereshevsky

 

From Associative Thinking: How to Connect Patterns and Creativity in Chess by Mikhail Shereshevsky
(Highlighted in IM John Watson's "Books and Beyond" column in the August 2025 Chess Life)

“How does one achieve a high level of play in all stages of a chess game? It seems that everything is simple: learn your openings, work on typical middlegame positions, practice calculating variations and improve your endgame technique. But as soon as you start working on any stage of a chess game, you will encounter the same problem — a huge load on the memory. … In any case, you will try to learn most of the information mechanically, which, of course, is boring and ineffective. What should you do? Stop rote learning, turn on your curiosity, come up with a vivid image for the technique being studied and remember it as an association. And most likely, at the right moment you will recognize it and understand how you need to act.”

Training quote of the day #56: Amishi P. Jha, PhD

  

From Peak Mind by Amishi P. Jha, PhD:

To Reclaim Your Whiteboard, Press Play  

I used to think mindfulness was about hitting the "pause" button, which to me always felt artificial or idealistic. Life has no pause button - why pretend it does? But when we're talking about stabilizing attention and developing a peak mind, what we're actually looking for is a play button. We need to stop holding down the rewind or fast-forward buttons and stay in play, to experience every note in the song of our lives, to hear and take in what's happening around us.

Annotated Game #328: What to do in the Colle?

This first-round tournament game highlights the dilemma of what to do in the early middlegame in the Colle. The critical point is around moves 9-11, where I decide to pursue a too-aggressive attacking posture on the kingside. My opponent correctly counters using his pressure down the c-file, but then prematurely throws away his advantage. However, I maintain my too-aggressive attitude and give him too much play on the 2nd rank, falling prey to a skewer tactic. I then made him work for the win, but he finishes off the game in a technically sound manner.

The main takeaways for me from the analysis are: 1) a better understanding of the dynamics around the e4 square in the Colle, 2) need for a more objective strategic mindset, and 3) the danger of ignoring CCT (checks, captures, and threats) when considering my opponent's options (see move 22).

Pop culture chess: Jaguar TCS Racing and Anna Cramling

Screen Capture from I Taught Chess to Professional Formula E Drivers

Periodically I run across and highlight prominent chess references in popular culture. Thanks to the Chess.com article "Jaguar TCS Racing Teams Up With Anna Cramling For New Campaign" I became aware of the latest major sports-related marketing campaign, apparently the first one since "Magnus Carlsen vs. Muhammad Ali". As one might expect, the production values in the videos are slick and the chess-related message is generally on point and consistent with sporting parallels, if perhaps a little dramatically overwrought:

“In chess, every piece has a purpose. Every move, consequences. Precision over impulse. Silence over spectacle. You don’t win by reacting. You win by knowing what’s coming. Five moves ahead. Ten, until the board bends to your will.”- Anna Cramling

From what I saw the chess itself is legit, although as can be seen in the screen capture, the analog clock - something at this point can be considered an anachronism - is incorrectly set. The chess set is also an art one rather than functional, although it does appear that at least the pieces are set up correctly. Full video is linked above.

Annotated Game #327: A (mostly) clean finish

This final-round game was won primarily due to my opening preparation in the Colle, which gave me a strategically winning position as of move 10. There is a big difference between a "strategically won" game and an actually won game, however, so the finish did not come without significant effort. Among other things, I once again missed a great chance for an impactful e3-e4 break with my opponent's king in the center, so will be more careful to look for that in the future. The final mating sequence included a rook sacrifice as a deflection tactic, which aside from the pleasing aesthetics is also an indicator that I am becoming less wedded to purely materialistic thinking.

Bronstein plays the Colle

The Colle is far from a "system" opening, although that is often its reputation. Taken from an opening study example, here is a fabulous game from GM David Bronstein, worthy of The Sorcerer's Apprentice. In addition to the rare king march at the end, what struck me most was the harmony of the White pieces as they dominated Black's rooks.

Annotated Game #326: Going against principles, and a lesson at least partially learned

In this tournament game I made a couple of key moves on general "principles" which in fact went against the actual principles inherent in this Advance Caro-Kann setup, most notably not exchanging off White's key knight on f3 when prompted. I also miss several saving/winning resources from my opponent, including the final march of the kingside pawns in the endgame. I will nonetheless give myself at least partial credit for the pawn sac on move 22 after castling (!) - should have done so earlier, naturally, but it was good to see the engine validate my choice to prioritize piece activity over material.

Annotated Game #325: You had one job [in the opening]

This next tournament game shows my failure to do the one job in the opening that is always strategically most important - open up the space in front of the opponent's king when it is still in the center. This is the one major takeaway I retained from reading GM Johan Hellsten's Mastering Opening Strategy, but in this game I still fail to apply it, either at the first opportunity on move 8, or on subsequent moves. This is all the more facepalm-worthy, since the e2-e4 break in particular is a well-known feature of the Colle. I was still even for the remainder of the game, but then transitioned into a slightly tricky NvB endgame where my visualization/calculation went wrong. This is another area to work on.

Annotated Game #324: A (mostly) clean start

In this first-round game as Black, I was pleased to have an almost entirely clean start to my last tournament. The Caro-Kann continues to perform well for me and it feels like putting on a comfortable, protective glove every time I go into it. My opponent was higher-rated, but in the Panov Variation was unable to get more than equality, missing the best follow-up to my one slip on move 19. While I also passed up a few chances for a little more pressure, I did not miss anything else significant, and correctly defended with "only" moves in the final sequence. I was also proud of resisting materialist impulses and avoiding the temptation to snatch the b2 pawn, which might not have lost, but would certainly have been fully compensated by White's subsequent initiative.

Lessons completed: Every Pawn Structure Explained by GM Johan Hellsten

I recently completed the lessons series "Every Pawn Structure Explained" by GM Johan Hellsten at Chess.com, motivated by the "Back to Basics" approach. The format consisted of 30 pawn structures explained with video lectures (816 minutes total), along with 5 "challenges" for each, in which you choose a prompted best move in the position presented. This is truly an excellent resource for learning different structural fundamentals important to all game phases (opening, middlegame, endgame) and becoming exposed to typical plans for each side. All of the content was useful for building fundamental chess understanding, and I intend to periodically revisit the key ones most relevant to my games. For a full content list, see the top link above. 

Overall comments on the lessons:

• The initial video presentation of the pawn structures and key individual piece placement - without the full set of pieces on the board - was an effective method for introducing the core structural characteristics for both sides.
• Similarly, the highlighting by GM Hellsten of "dream positions" for both sides, including typical pawn/piece formations and breaks, as well as guidelines for piece maneuvers and exchanges, was very helpful for understanding middlegame planning and strategy.
• It might have been a bit more thematic to group together all the similar opening structures in the default order of the lessons' presentation, for example to have the Sicilian-related ones be sequential. However, one can do that manually by selecting "a la carte" from the full lessons list, as they don't have to be completed in the designated order.
• I found the "challenges" - basically "find the best move" quizzes typical - to have varying utility and comprehensibility. The initial prompts for the type of move to find in the position were sometimes a bit obtuse or misleading for me. For example "How do you win material?" was sometimes problematic, especially when the answer turned out to be an obvious capture with no additional material beyond that actually gained. The selection of GM-level games also meant that some of the tactical ideas were rather complex to visualize and discover - otherwise, of course, the losing GM opponent would have been able to see and avoid them in the first place.

Comments on the most personally relevant topics:

• The Isolated Queen Pawn (IQP) presentation kicks off the series, with a very lucid and thorough explanation of general principles, plans involving specific squares and pieces, and thematic tactical tricks involving the IQP. The explanation and illustrations of this common and imbalanced structure were the best that I have seen. In my games, I can reach it via either White or Black based on my openings, so it was also very relevant.
• The second video on hanging pawns was similarly enlightening for both using and combating them, again very relevant for the positions I can reach in the middlegame.
• Next came the Carlsbad structure, which despite playing multiple openings where it can result (as both White and Black), I had never really studied it in-depth before. Explanations of the typical plans are clear, although I'd have liked to have seen the typical queenside minority attack better illustrated with examples. As compensation, there is a brilliant illustrative sacrificial attacking game for White in the kingside attack scenario.
• Later on, the Hedgehog - which seems to be less popular nowadays - received an interesting treatment for both sides, although the typical White side setup normally reached via the English Opening with a fianchettoed light-square bishop was not presented.
• The Advanced French and Scandinavian structures were also very useful to see, since I will often get them via the Caro-Kann.
• GM Hellsten did a particularly good job of clearly explaining the central features of the Stonewall structure, probably the one I have the most practical and theoretical familiarity with. It was helpful to reinforce my understanding of those, plus draw attention to some attacking ideas like the f-pawn push.

Book completed: The Dutch for the Attacking Player

 

I recently completed The Dutch for the Attacking Player by IM Steffen Pedersen (Batsford, 1997), having originally purchased it in the 2000s soon after getting back into tournament chess. I previously looked at it mostly for casual entertainment purposes, although at one point I evidently transcribed some of the lines into my repertoire database. A little while ago I decided to actually learn (and start to play) the Leningrad Dutch, which has the image of being one of those cool, kind of scary openings that is only supposed to be for aggressive tacticians. This was certainly not my "playing style" for most of my tournament career, but I figure now is the time to put aside the fear of it and pursue something that brings more joy to to my chess experience.

Although this book is not my principal resource on the Dutch - I'll share details on that once fully completed - it was still good to seriously go through it after all these years, with a more knowledgeable approach to the opening, now that I have some other resources to compare it to. Some of its contents hold up better than other parts, which is what you would expect for a book published in 1997. 

Here is the contents page:

To provide some background and flavor from the author, below are two excerpts. 

From the preface: 

From a very early age I learned that the weakest spot from the very start of the game is f2 for White and f7 for Black. With this in mind, it seems that one ought to refrain from playing a move like 1...f5, but no one has yet demonstrated a concrete reason why it is wrong. From when I started playing international tournaments the Dutch has been a part of my repertoire. Even though I have come close to abandoning it on several occasions, I keep coming back to it.

At the outset, I should say that the Dutch can be an extremely difficult opening to handle, but please perservere, and I will try to show you that there is nothing better than winning with the Dutch. The funny thing is, though, I would never dream of playing 1 f4 as White!

The book is written for the ambitious player, who would like to play for a win as Black. Therefore, I have focused exclusively on the Leningrad variation. It is a repertoire book, i.e. against every system at White's disposal, I have chosen one or two lines that I believe have the brightest future (omitting lines in which I do not believe) and included suggestions against 1 c4 and 1 Nf3 as well. 

From the introduction:

The Leningrad Dutch can be a very difficult opening to handle. Indeed, I have suffered some terrible defeats with it myself and almost given it up. But believe me, there is no need to do that. Only by experience can an opening be learned and the occasional loss is inevitable.

Comments:

• As can be seen from the above excerpts, the author was a contemporary practitioner of the Dutch and (per the cover page) scored a grandmaster norm at age 16 using the opening. The best opening resources I have found come from people with real tournament experience in that opening; among other things, it gives them a practical feel for what works at the board, beyond pure theory. (This was similarly true before the era of modern engines, since there has always been a "best theoretical line" in existence at any given time.) It helps give the student more confidence as well, since the recommendations have been battle-tested. In this case, Pedersen includes his own tournament games among the examples.
• I appreciated the introduction containing broader structural ideas for Black and White (the ...e5 advance, playing on the kingside, playing on the queenside) before getting into the chapters on different variations and setups. Framing overall goals and showing key moves and typical piece placement help tie together opening concepts thematically.
• The first chapter on the Leningrad main line for the book I ignored, since it only covers 7...Qe8. This used to be the most popular choice for Black (and was played by the author), but it has since been largely dropped at top levels due to the discovery that White's line with Re1 provides a consistent theoretical plus. I'm sure it's still playable at the Class level, but 7...c6 has been the professionals' first choice for a while now.
• The rest of the book was still relevant for me, however, since there is a lot of territory to cover outside of the main line setup that begins on move 7. The Dutch is similar to the Sicilian opening in that respect, with early "Anti-Dutch" variations beginning as early as move 2 that cannot be ignored. Move-order and transposition tricks are common, and something that a practical player like Pedersen is able to provide useful insight into. One of the most important ideas is to avoid committing too early to ...g6 if White can advance the h-pawn and then get to h5 with their queen; this can mean postponing the fianchetto, or even going into hybrid Classical or Stonewall Dutch-type structures on occasion.
• Like any opening resource, the book was treated as informational input into my own custom-built repertoire, with each chapter's material evaluated and explored further with a database/engine setup. Some of the examples and variations, as you might expect, are outdated or do not hold up to modern analysis. However, older sources like this sometimes provide interesting ideas which engines can confirm are workable, but do not appear in contemporary practice. Looking at middlegame examples for piece placement and thematic ideas is also always useful on a general understanding level.
• On a technical level, in the latter part of the book I caught two serious variation errors (with missing moves that could not be reconstructed) and one diagram error (a missing rook). Other than that, the editorial quality was good.

Training quote of the day #54: Amishi P. Jha, PhD

 

From Peak Mind by Amishi P. Jha, PhD:

Time to Start Training 

Imagine a moment that calls for physical strength. Say you're about to help a friend move a piece of furniture. You approach the heavy couch, realize you're not up to the task and . . . drop to the floor and begin to do push-ups in an effort to gain the strength you need.

If that sounds silly, consider that this is what so many of us do every day, constantly, when faced with cognitive challenges - instead of developing a training regimen, making it a habit, and doing a little bit each day to build up our capacities, we drop and try to eke out a "mental push-up" or two once we're under stress or in crisis, the whole time believing that it will help and that we'll be able to stand up and "lift that couch." Instead, we'll only be more depleted.

We need to start training now, both for the period of high demand we may be in currently, and for periods of demand we'll face in the future. 

(Updated) game analysis for improvement in play

Game analysis setup with CB18

At the start of this blog, which coincided with a new phase of more serious (and continuing) chess improvement efforts, analyzing your own games was identified as the necessary heart of an improvement strategy. This continues to be the central driver of the process for me, which is essentially an ongoing cycle of self-diagnosing issues with my game, then investigating and applying the chess knowledge gained as a result.

There are multiple guides on doing your own game analysis out there that may be helpful - although I've found some of them lacking sufficient detail on the "how" part of it, or sometimes recommending particular procedures that I don't find practical for my own purposes. Since the methods (and some of the tools) I've used have shifted a bit since "Game Analysis For Improvement in Play" was originally published, I thought it would be worth providing an updated analysis methodology outline. Caveat: this is not necessarily a template that will work best for everyone's practice, or that should be followed 100%. Rather, the intent is to provide a example of practical study methods in action. (I am a big proponent of the "whatever works for you" school of training, covered in more detail in "Do study techniques matter in chess?")

Some core tools are required for any setup: databases (at minimum one with your games, paired with a large reference database for comparison); an analysis program/GUI; and a top-class engine. Widely available options, both commercial and free, are covered in detail in the Chess Computing Resources (2021) post. Despite the age of it, the relevant links still work, and you just need to make sure to get the latest versions of the products; some of the main computing resources are also permanently linked in the sidebar. (For reference, my current analysis setup is displayed up top: ChessBase 18 running with the Dragon 3.2 engine and Annotated Game #323 displayed.)

Here's a description of my current step-by-step process, which typically takes around two hours for a fully annotated game:

• The game is entered into the database; I have one for all of my tournament games and a separate one for training games. If you are playing online at Chess.com, lichess.org or other sites, normally you can simply download a pgn file of your game and copy that into your database. For OTB games, naturally you'll have to enter it manually via your analysis program GUI - unless you're part of the elite where you play on an electronic board that records all your moves in the cloud. 
• During a tournament, I will make sure to enter all the games into the database before it is over. However, this will not necessarily happen on the same day they were played, if I'm too tired. Because it would be too much of a time and energy suck, I won't do a full analysis of my games while the tournament is ongoing, but I will normally take a quick pass through them with an engine running in order to validate (or refute) my understanding of what just happened in them. (For example, I would feel stupid to get caught out by the same error twice in a tournament.)
• During the initial manual entry of moves, or as a first pass during the analysis process if the full game notation is already copied, I capture my thinking process on significant moves in text comments. This could start as early as move 1, if the opening selection choice is worth mentioning, or it could start at the end of a typical main line sequence. In any case, I don't worry about polishing the language for publication, since it is more important to first record the thought process (whether accurate or flawed) and any other significant considerations at the time (physical or emotional stress, time trouble, etc.) that may have affected decision-making. This is also a good time to record other candidate moves that you considered, along with any related commentary and/or sample variations.
• During a full analysis session, I review the game from the beginning move-by-move with a reference database and engine running. Normally I will also have my opening repertoire database up in a separate window, so I can refresh my memory of the relevant opening line and note any deviations made by myself or my opponent. Here is where I will also investigate any new moves in the opening - new to me, at least - and update my repertoire database as needed. Considerations at this stage include the move's score percentage in the reference database, combined with the engine's evaluation and my own understanding and preferences in the opening line we are following. It is often useful to review some of the master-level games in the database that continue in the line being examined, to get a better idea of resulting middlegame positions and plans.
• After the "book" opening phase is past, the analysis process is devoted to examining and validating (or refuting) the actual moves played in the game, comparing them with the engine's and database's top other moves (for as long as the database has identical games). I normally have the top 4 engine moves displayed for variety, to get an idea of what good candidate moves are available in the position. Key variations are identified, understood (important!) and entered into the commentary, including alternative viable strategic plans and any tactical opportunities/threats overlooked (sometimes by both players). During this process, while the engine serves as an excellent reference, it is very important to avoid simply taking the top engine line for granted as "best" in a position. This is something which especially should not be done if you do not understand the moves it recommends. ("Pitfalls of Computer Analysis" goes into more detail regarding the practical considerations of using an engine for analysis.)

It was surprising to me how much rich content could be derived from just one reasonably thorough analysis of a tournament game. Especially when done regularly and in a timely fashion - something I have not always been the best at - it also inevitably highlights meta-trends in your performance. For me, that has included the recognition of a lack of a consistent thinking process, recurring flawed moves in a particular opening, or a repeated failure to maximize piece activity. Perceiving and rectifying these types of bigger problems with your game, not just identifying individual blunders that are made, can represent a major investment and payoff in long-term improvement potential. Sometimes, of course, positive trends in our game are also highlighted; it's especially important to recognize and celebrate when your mental toughness helps you draw (or even win) a lost position.

Some other typical training benefits I've observed, after employing the above methods:

• Openings: playing, then reviewing and analyzing what occurred in the chosen opening, has been the most effective way for me to understand more deeply and then remember opening lines for future use. This process also naturally results in the refinement of your repertoire based on new information and the practical challenges being encountered in your chosen lines at the board; there really is no better feedback loop.
• Tactics (and not just for the middlegame): what tactics were completely missed? Seen but miscalculated? Visualized improperly? Recurring patterns such as missing the idea of potential backwards piece moves, not visualizing discovered attacks that appear after several moves of calculation, etc. are in fact common phenomena. Although we cannot completely eliminate them, being more consciously aware of these issues in your games and mentally calling them out can help us overcome these blind spots.
• Candidate moves: in both the middlegame and endgame, the number of different types of candidate moves considered (both positional and tactical) has expanded significantly for me. Other than highlighting specific forced wins or clear blunders, this I believe is the most important function of engine assistance in analysis: showing the player possibilities that they would not otherwise have considered (either at the time, or during unassisted analysis).

As mentioned above, I believe the exact methods used are probably not as important as the fact game analysis is consistently occurring at the effortful study level for a player. In fact, I think it would actually be rather difficult to avoid improving your game as part of this process, if it is done regularly and you deliberately follow up on what you discover with both curiosity and a positive intent to apply the lessons learned.

2025 U.S. Chess Championships off to a good start (for some)

The 2025 U.S. Chess Championships have kicked off. Round 1 featured some interesting games and decisive results, with two in the open section and three in the women's, including one by GM Irina Krush shortly after she was inducted into the U.S. Chess Hall of Fame. GM Fabiano Caruana won by taking his opponent (and normally his second) GM Grigoriy Oparin out of normal lines early - a good strategy against someone who knows your usual preparation.

Full round 1 coverage from Chess.com is at https://www.chess.com/news/view/2025-us-championship-round-1

The main tournament site can be found on the host St. Louis Chess Club's event page - https://saintlouischessclub.org/event/2025-us-chess-championships/

I've already begun downloading selected games of interest for at least an initial review. Some of those then I expect will be added to my (longstanding) queue for full commentary game analysis (see "Analyzing master games for training").

Annotated Game #323: Shoulda, coulda, woulda...

The thematic title for this last-round game analysis ("shoulda, coulda, woulda...") refers to the slang expression for regretting missed opportunities ("Shoulda done this, coulda done that" etc.) This game followed directly the same day after the rather exhausting Annotated Game #322, so I'll ascribe my calculation fatigue to that circumstance. That said, after an exchange of somewhat complicated tactical blows it's a simple oversight (a backwards minor piece move by my opponent) that seals my fate. I do not go down without a fight, though, and make him work for the extended endgame win.

Although I scored poorly in this tournament, I actually didn't feel terrible about my overall level of play. My opponents were all higher-rated and I managed to obtain what "shoulda" been winning positions in my last two games. It was therefore not a case of me thinking "I'm terrible at this game!" and wanting to quit after getting blown off the board repeatedly. So with some adjustments in my game, I'm looking forward to my next tournament, which I expect to be sometime in November.

Annotated Game #322: Calculated disappointment

This next game was my most disappointing of the tournament, although it also was my only score and I therefore avoided "castling long" (0-0-0) on the standings sheet. I was slightly surprised by my opponent as White choosing the Panov Variation of the Caro-Kann, since these days it seems a lot more people play the Exchange Variation with this move sequence start. In any case, I was still well-prepared to take advantage of an early mistake by him on the queenside, and for most of the game I had what should be a strategically winning advantage.

Although there are a couple examples of less-active piece placement here, that was (thankfully) not the main theme of the game. My calculation (and evaluation) was sub-optimal in several key instances. In two cases, it even resulted in minor panic when my opponent found a backwards bishop fork - thereby equalizing - and when I thought I might be in trouble due to my opponent's charging passed a-pawn in the endgame. While the late middlegame issues were in large part due to time pressure, that points to managing the process better, and also hopefully thinking more clearly before then to begin with.

Blogs That Used to Be Good (and might be again)

These chess blogs used to frequently titillate the reader with witty, useful or simply entertaining content, but no one really knows when they'll be updated again or if the blogger still cares about his/her followers. Bloggers who are dead (or at least dead to the chess world) are ineligible. 

Today we have a new entry in the above-linked collection - also in the sidebar - of (formerly?) great chess blogs: TheOnoZone's Blog at lichess.org. I've recently gotten active at the site, mostly for purposes of playing more regular online training games versus humans, and have also dipped a curious toe into the blog feed. 

The post entitled "Your (Chess) Personality" was the first one to catch my eye, since the chess style/personality topic has been one examined here as well, in "Playing Styles Deconstructed". "Ono" is an excellent writer, and has a somewhat different (and much more entertaining) take on it. I was going to leave a pithy comment on that particular post, to engage on the subject, then noticed it was from 2022 and that the last blog entry was from November 2024. It's therefore been gone long enough to qualify for the (dubious?) honor of inclusion on this list.  

Because chess improvement is an evergreen topic, I'd say that all of the blogs in the linked list are still worth perusing, even if Temposchlucker's is the only one currently active. If he can resurrect himself, however, perhaps there's hope for TheOnoZone's return.

Annotated Game #321: The supremacy of piece activity

This next tournament game follows a common pattern that has been more evident as of late, a lack of an ability (or desire?) to maximize my piece activity. The game itself is reasonably hard-fought, but after I end up with an isolated queen pawn (IQP) in the middlegame, piece activity becomes even more important to offset the long-term structural weakness, and my play is not up to the task. Structurally, I should have opted for hanging pawns, since my pieces were actually well-placed to support them. As is the case with many "lost" games, my opponent gave me opportunities to re-enter it on even terms. In particular I failed to spot the "heroic" engine defense (as I labeled it in the annotations) on move 35, which is an excellent example of the supremacy of piece activity, as opposed to an overly materialistic and sometimes passive approach.
