Annotated Game #217: Recovering in the middlegame

After my first-round victory against an Expert (Annotated Game #216), I had a short draw against an equally-rated player. My rule these days is not to take draws unless the position is in fact drawn with no real play left. Although it was still technically the middlegame, I would say it met the criteria and the engine assessment corroborates that, so I don't feel bad about the result. It also let me conserve energy for this next game, which was again against someone 300+ rating points higher.

The story of the opening into the early middlegame is unfortunately a familiar one. In an English vs. Queen's Gambit Declined (QGD) structure, I do fine for the first 10 moves of "book" and then flounder in an unfamiliar position. One of the insights I've had is that this is in fact a completely normal phenomenon. The point being, learn the ideas of the position through game analysis afterwards, so the next time it will be familiar. I believe this is one of the most powerful ways of improving your game on a practical level. It also means that frequent tournament/serious chess and post-game analysis is necessary.

Unlike in a number of previous games, I manage to recover after the rather silly 10. Na4?! and break the trend giving Black the initiative. It's interesting to see how early trends in a game often take psychological hold and a small but real advantage for one side just keeps getting (unnecessarily) larger. Here, Black has pressure in a complex position through move 13, then allows me in the next several moves to simplify and improve the relative position of my pieces. By move 17 I feel much better about the position and by move 22 things are completely level.

However, that doesn't mean that there were no more opportunities to go wrong. My opponent kept trying to create chances for me to degrade my position, for example on moves 37 and 41. The latter one is instructive, as one typical Class player error is to always take an even material exchange, in the belief that it will lead to a quicker draw. That's not what the position demanded, though, and the draw was sealed soon afterwards.

One GM comment I recall reading a while back noted that against lower-rated players, masters can often get significantly behind coming out of the opening, but then draw or win in the end after their opponents make a key error, typically close to or in the endgame. This seemed to be my opponent's thinking as well, which I can't fault him for. One of the differences in this game is that after recovering in the middlegame, I did not let up in my focus and calculation, assuming that it would be drawn; games don't magically end themselves (or if they do, it's likely because of a blunder on your part). So although my level of play in the first part was sub-par, it was good to see that I had what it took to go the full distance in the game.

On improving to the master level

An honest answer to the question:
If you happened to be at around 2000ish for a while, what do you think helped you improve past that to 2200? After being stuck for a while at 2000 I took a break for a year and I am contemplating whether to start playing in tournaments again.
Can be found here, from a newly minted master: 
The short answer: play frequent tournament games, and pay close attention to which structures and strategies work best for you. Also, don't rush when you have an advantage.

Training quote of the day #25: Artur Yusupov

GM Artur Yusupov, in Training for the Tournament Player:
What enables a chessplayer to be successful? In response to this question two essential factors are usually singled out: talent and hard work. But it is not sufficient just to be talented and hard-working. Physical condition, competitive character and the ability to concentrate during play are also very important. No less important is the ability to choose correctly the direction that such work should take and to be able to reach the required standard. Needless to say, this task is far from easy...
Of course, in order to be able to choose a direction leading to self-improvement it is necessary to have a critical understanding of one's game. The authors are totally convinced that the serious study of one's own games is an essential requirement for any chessplayer who wishes to improve. Therefore the theme 'analysing one's own games' occupies a central place.

Video completed: "Why You Should Never Give Up in Chess" by Tatev Abrahamyan

"Why You Should Never Give Up in Chess" is the fourth video in the new Chess.com series by Tatev Abrahamyan. Like the others, it is around 15 minutes and presents its main theme using some narrated game examples. She states in the intro that the point is not to play on when mate is inevitably coming (which seems to be the fashion these days in OTB tournaments at the Class level) or if you are losing all your pieces. Instead, it's to take advantage of the fact that winning a supposedly won game is not automatic. She reminds the viewer of all the times that you may have thrown away a win after you thought it was a done deal, which I think is something relatable for many of us, and an excellent motivator on the flip side for playing on.

The first of the games is Frank Marshall - Georg Marco, in which the American chess legend manages to work some endgame wizardry versus his opponent, who had an advanced, unstoppable passed pawn. Marshall plays actively to complicate the position and obtains chances when his opponent loses focus on his winning idea, forcing through the passed pawn. Although the pawn does queen, Marshall now has a brilliant tactical resource available, coordinating his rook and knight to win it. While the position is probably drawn afterwards, the psychological blow is too much for Black and he goes on to lose. This illustrates how continuing to fight back, even if objectively losing, can still give you the opportunity for real chances and change your opponent's mindset from winning to losing.

The second game, IM Anita Gara - GM Irina Krush, highlights the tricky nature of rook endgames, which means you should not give up in them. The video picks up the action on move 103 (!) with White in a winning position, having an advanced (7th rank) rook pawn that is passed, with Black's king and rook on the other side of the board. This turns into a RvP endgame that Black manages to hold, once White makes a crucial error. Exhaustion is naturally a factor, as is Krush's knowledge of tricky endgame principles.

Abrahamyan mentions in passing GM Sam Shankland - GM Anish Giri, which is infamous for Shankland resigning in a drawn position, then moves on to the final game, GM Alexander Beliavsky - GM Larry Christiansen. White is up a pawn with an excellent position, so Black has to (in Abrahamyan's words) resort to desperate measures. As in the previous game, a stalemate motif is used by the losing side, except in this case Christiansen finds it from an unexpected middlegame position.

This is another good entry in the video series, both for the psychological and the technical ideas behind using every resource on the board you may have, in order to give yourself chances to save a losing game. The flip side of that coin is the idea is of giving your opponent the most chances to go wrong.

Annotated Game #216: Starting the breakthrough

This first-round tournament game, a win as Black against an Expert, started my breakthrough in performance from Class B to Class A (see "The Long Journey to Class A"). I had to get up on a Saturday morning and force myself to drive to the tournament, which afterwards I was glad I did. I'd been playing pretty regularly for the previous four months (one tournament / month) but had rather meh results. I was not looking forward to another mediocre tournament. However, diligence appeared to pay off and my game was elevated enough to produce better results over the board.

We reach an interesting and unbalanced position in the main line Slav (with the 5...Na6!? Lasker variation) by move 10, with my opponent deliberately inviting doubled f-pawns in exchange for potential play down the g-file. At 300+ rating points above me, I could tell he was clearly looking to create winning chances in an imbalanced position. The next several moves were critical and both of us missed chances to improve on the game score. A key idea was fighting against White's idea of f4-f5 to crack open my position, which at first didn't work. After my dubious 16th move then it did, as analysis shows, however neither I nor my opponent saw this.

By move 19 I've sufficiently protected the critical f5 square and the strategic nature of the game shifts, as White runs out of ideas and I take over the initiative. I exercise the simplest (and most effective) plan of building pressure down the d-file, which was largely risk-free, although there are some interesting possibilities in the variations. I was particularly pleased to see my two knights clearly better than my opponents' two bishops, which is a rarity in the Slav.

The winning blow comes as my opponent, under pressure, tries to cover his weak f-pawn, but fails to see a naked knight sacrifice that delivers check, picking up the exchange and a dominating position for Black. After that the win was just technical, although White held out until mate; as I mentioned in an earlier post, this seems to be much more the norm these days. It was slightly ridiculous, although there was perhaps a glimmer of hope on his part that I'd overlook a mate.

While it was not a clean game, I felt reasonably good about it afterwards, both in (finally) finding a way to stymie my opponent's pressure, and then in seeing the winning tactic (25...Nc3!!) - the double exclamation points being awarded by Komodo via the Fritz interface. It's nice to see the engine give positive feedback, now and again.

Slow Chess League: August tournament signups now open

Since I moved earlier this year, I expect that playing in OTB tournaments won't be part of my future for a while, at least not on a regular basis. This was the same situation I was in when I started this blog, but I was able to find useful tournament-style games online at the Slow Chess League. Their August tournament signups are now open, I plan on participating in the 45/45 section.

In general, I find that the game quality isn't quite as good (on my part) when playing at that time control, versus the OTB longer ones that I prefer. However, it does encourage more ruthless and efficient thinking, which helps in all aspects of chess.

Training quote of the day #24: Jay Bonin

From IM Jay Bonin's Active Pieces: Practical Advice from America's Most Relentless Tournament Player
When asked about my own study habits, or - more directly - when someone asks, "Jay, how did you make it to 2400?", I don't always have a great answer. I never had a coach, and in the '70s and '80s as I was climbing the rating list, game databases, chess engines and computers in general were neither as powerful nor as ubiquitous as they are today. Taken together with the fact that the Internet had not yet created the possibility for the instantaneous and free exchange of information, this meant that as an autodidact I had little in the way of formal training other than what was available in Chess Informants and Shakmatny Byulletens when I could find them, and taking the time to thoroughly understand the critical positions in the games published there. I would try to understand not just the tactics that occurred in a game, but the missteps that led to them. Ultimately, I learned by playing stronger opposition and subjecting my own games to the same scrutiny.

Annotated Game #215: Getting away with a pawn and a win

In this final-round tournament game, after a series of draws, I was looking for a win. The Classical Caro-Kann has been a good opening in terms of scoring wins for me, so I was happy to see my opponent choose it as White. She varies from book with 12. c4, which allows Black to equalize easily. I saw an opportunity to grab White's advanced h-pawn and took it on move 14, which defined the resulting strategic struggle. White could have played more actively, with sufficient compensation for the pawn.

Over time, I am able to consolidate the pawn advantage and make sure that subsequent material exchanges were to my benefit, ending up with a winning double rook endgame. As is common these days, my opponent (a junior) played on until mate. I used to find this practice both annoying and disrespectful, but it seems to be the way competitive chess is now almost universally taught at the scholastic level. Now I just enjoy playing out a winning position (being grateful that I have one) and don't worry about trying to find the absolute quickest path to victory. An easy and safe win is just as good, and it considerably reduces the stress and annoyance factor.

Although I don't quite overdo the pawn-hunting in the opening, it's still enough of a distraction (and detraction) from my game. Seeing in the analysis how White could have taken better advantage of it is instructive. In the future, in a similar situation I would likely play more conventionally rather than chasing the pawn, also bearing in mind the lessons of "Don't Be Greedy in Chess".

Video completed: "Don't be Greedy in Chess" by Tatev Abrahamyan

"Don't be Greedy in Chess" is the third video in the new Chess.com series by Tatev Abrahamyan (under the title 'Why You Should Never Be Greedy'). Like the others, it is around 15 minutes and presents its main theme using some narrated game examples.

The first example is the miniature GM Peter Wells - GM Alexei Shirov. It's an interesting Trompowsky Opening that Shirov treats aggressively. Abrahamyan makes the first mistake I've seen in her video series, missing 6...Qxh6 (the more important reason why White doesn't take with the queen after 5...Bh6) although it doesn't change the evaluation of the position. (This is also mentioned in the comments section and one would think that a minor edit to the video would be in order. However, for some reason it seems that professional chess videos are almost never edited, even when obvious mistakes are made, a perennial complaint of mine with ChessBase products as well. This is the 21st century and digital editing tools are easily available.) In any case, Black gets greedy and grabs a rook, allowing White to develop faster and separate Black's queen from the action against his king in the center. White originally also had very limited development, so perhaps the situation did not seem urgent for Black. Abrahamyan has sufficiently long intros for the key moves for White, allowing you to do some of your own thinking about them.

The second game, an older one, focuses on the problems involved with taking too many pawns in the opening. The White side gets a huge lead in development as a result, forcing Black's king to remain in the center (sound familiar?), then some sacrifices flush the king out into the open. The third game is GM Judit Polgar - GM Ferenc Burkes. It is a more subtle example, where Black's decision to tactically win material in fact gets him in trouble. White creatively passes up taking material in favor of focusing on an h-file attack, which eventually gets her the win. This is also another example of where 'problem-like' tactics (no forced mate or win of material) are not present initially (so you can't really "solve" the position) - both accurate calculation and strategic judgment are needed. The finish involves a fully calculated h-file sacrifice that's worth seeing.

The video's lessons were all on point and Abrahamyan allowed much more time for pausing to consider key positions, a technical improvement on the first two videos.

Annotated Game #214: Why you should never rush (redux)

It often happens in chess training that the topics you are studying become immediately relevant to your game analysis. In this next tournament game, Tatev Abrahamyan's "Why You Should Never Rush" highlights the main theme, since at several points I could have exercised more patience and maneuvered to keep remorselessly squeezing my opponent, rather than simplify or release tension.

Another key idea revealed during analysis was the missed tactical opportunity on move 14. Unlike many tactical problem drills, there was no immediate mate or forced loss of material, but the sequence would have given me a far superior, even winning, position.

Strategically, the struggle revolves around the creation and then targeting of Black's isolated queen pawn (IQP) and the near-ideal circumstances for White in exploiting it. However, my opponent never gave up and in the end she did a good job of holding the endgame draw.

Chess success vs. professional success

Photo from https://drprem.com/business/astonishing-similarities-chess-business-strategies
I have to admit I'm a little leery of some (well, most) of the business books and articles that use chess as a basis for how to achieve success at work. This isn't a phenomenon limited to chess of course, as everything from Sun Tzu's Art of War to Shakespeare's speeches to "mindfulness" has been touted as a (or often the key) to professional success.

A brief internet search will pull up various things such as the article linked to the above picture, which looks very modern, stylish and professional, except that the chessboard is all one color (?) - at least the pieces are set up in the right order.  This illustrates one of the issues with the genre: most of the time, business writers aren't serious chessplayers who understand the game at any depth, nor do most professional chessplayers have a top-level business or managerial background. And even then, one can easily stretch chess metaphors too far as a writer.

All that said, having worked to grow in chess strength over the years ("The Long Journey to Class A") while also having gained professional management experience at various levels, I can say there are some very useful parallels in terms of skills and approaches that a person can use in both arenas.  I don't know if there's a book-length lesson in there, but I recently boiled the principles I consider most relevant down to around a 45-minute presentation for a group at work.  (They had found out I was a chessplayer and expressed interest in a presentation on the topic, so I said why not.)

Here's a lightly edited version of the outline.  I called it "The 4 Ps" because business presentations are all about catchy, easily remembered alliterative lists.

Preparation - take care of how you show up to each game / workday
  • Mental – focus, calmness, objectivity in assessment
  • Physical – endurance, sufficient rest and recovery, healthy distractions
  • Presence and attentiveness

Planning and evaluation - consciously make an evaluation of each position / situation
  • Learn when to apply general rules and procedures vs. using your personal judgement in specific situations
  • Pattern recognition – take advantage of this “automatic” analysis derived from experience. ("I've seen this movie before...")
  • SWOT analysis (Strengths, Weaknesses, Opportunities, Threats) of a position / situation
  • Know the “why” of what you are doing. Never decide to make a move / take an action without being able to express clearly what it will do (and not do)
  • Balance between following a plan and adjusting to new circumstances

Perspective - ask yourself what can the other side can do
  • You control only your own sphere of action. The rest either someone else controls, or it is uncontrollable
  • Thinking ahead: understand the action – reaction sequence of an initial action (calculating "X moves ahead")
  • Unless you deliberately adopt a different perspective beyond your own "side", you won’t see others' possible reactions, so can’t get ahead of the action-reaction curve

Post-match learning - understand what happened and why
  • Even when you are successful, there is always an opportunity for learning and critiques
  • If you lose / fail, understand why and identify the lessons for improvement for the next time
  • Articulate to yourself what you did well and what you need to work on. Welcome constructive feedback from others, as it will help inform you

Commentary: Women's Candidates 2019, round 9 (Gunina-Goryachkina)

This game between GM Valentina Gunina and GM Aleksandra Goryachkina during the recently-completed Women's Candidates tournament is much more exciting than my Annotated Game #212, which featured the same unusual Caro-Kann opening. Goryachkina, the eventual winner of the tournament, also uses the idea of the knight exchange on e4, but then varies with the idea of ...Qa5 followed by ...Bf5, targeting White's queen. This idea (along with Magnus Carlsen's 5...Bf5, shown in the previous game) are good opening knowledge takeaways.

The main clash of ideas comes after Gunina's early, aggressive 13. g4. Pushing the g-pawn while your king is in the center or on the kingside is one of those ideas that can be great when it works, and terrible if it doesn't, so each case has to be evaluated individually. Here White starts to get in trouble a few moves later, once Black is prodded to swing her queen to the kingside to occupy the h4 square (a hole left behind by the g-pawn's advance). After that there is a ferocious struggle, but Black calculates bravely and well and keeps the win in hand the entire time. This type of fearless, dominating play is something to emulate.

Annotated Game #213: Charting your own path

During this next tournament game, my opponent and I chart our own path early on, outside of what is covered in opening books. But it's not really new ground, once you start looking in the databases. In what is ostensibly a rather offbeat sideline of a Caro-Kann Two Knights, you can find super-GM level games by Carlsen and Topalov on the Black side, which are given below. (And the next Commentary game to be posted will feature a very recent game in the same line, from the 2019 Women's Candidates tournament.)

These days, especially with Carlsen as a model, players seem less obligated to try to duel for a theoretical advantage in main lines, although there's still a lot of opening theory that continues to evolve. I used to have an unhelpful attitude towards opening "deviations", thinking that they should always be punished. Now, I think it's more important to know the key elements of an opening position, both static and dynamic, which will then be your guide - regardless of whether the line you're in is popular or even known. Analyzing your own games when you enter unfamiliar territory is always a good learning experience, since both your knowledge base and insights should grow as a result.

In this game, the main insight for me from Carlsen's different choice on move 5 is how to take advantage of White's Qe2 blocking the standard bishop development. Later on, the queen's early sally on the kingside also offers opportunities for Black on the queenside. I decide to follow a more aggressive plan with opposite-side castling, which offered the clear idea of advancing pawns on the kingside to pressure White. This isn't done in the most effective way, and I also miss some key ideas repeatedly (...Qd5!?), which I'll remember for the future. There's a lot of back-and-forth and White was dangerous in the endgame, but I finally managed to get a draw. My opponent was rated about 100 points above me, so not a bad outcome of an interesting game.

Video completed: "How to Take Your Time in Chess" by Tatev Abrahamyan

"How to Take Your Time in Chess" by Tatev Abrahamyan, the second in her new Chess.com video series under the heading "Why You Should Never Rush", isn't about the time on your clock, but rather the idea of not rushing your play in a position. Although she doesn't actually use the word, it's another way of looking at the need for patience - even when you have obvious threats you can make on the board.
  • During an attack: don't rush, because all pieces need to be involved. Launch a premature attack, you run out of pieces. Once all pieces are developed and ready, then look for breakthroughs.The first game example featured GM Gukesh Dommarju (the 12-year-old Indian) vs. IM Dinesh Sharma. As happened a couple of times in her first video, there was some too-rapid narration the first time she suggested to pause and find a move, but that improved afterwards. 
  • Don't rush executing a threat. This second example featured Aronian-Nakamura, from this year's St. Louis Rapid and Blitz tournament. White has a dominant position, but rushes with the threat of pushing an advanced passed pawn. (Again proving Nimzovich's dictum that "The threat is stronger than the execution.") The game is also a good example of the previous video's header ("Why You Should Always Ask What Your Opponent Is Up To"), as the main problem for White is Black's counter-threat on the king, that could have been blocked.
  • Pushing too much / too far creates long-term weaknesses. The final example is Giri - Nepomnniachtchi (Tata Steel 2019). Here, White (Giri) gets into trouble by pushing pawns and creating a series of weaknesses. Another reminder of the fact that pawn moves are ones you can never take back, and they always leave behind weaknesses.
One of the things I've appreciated about the chosen examples is that the problem moves often look very reasonable and normal, not like they should provoke punishment by the opponent. This helps reinforce the idea of always checking your moves and not relying on the assumption that everything is fine. Abrahamyan in her narration also consistently does a good job of pointing out why certain moves aren't made due to different tactical consequences.

Finally, it's worth noting that the running time of the videos in the series (15-20 mins) is good for absorbing meaningful content in a single sitting, without losing focus.

New comment moderation settings and policy

Until now, I've allowed unmoderated comments on the blog, although a Google account was required to post. There's been an uptick in spam comments on the more popular posts, though, so I've switched to full moderation. However, I've also removed the Google account requirement, so it's less restrictive in that sense.

Basically I'll welcome (and respond to) any comments that aren't spam, trolling, or ass-hattery. It's always helpful to see other chessplayers' opinions on topics, whether talking about general concepts or more specific analysis (like laramonet's recent comments on a Symmetrical English variation that's worked well for him).

Video completed: Tatev Abrahamyan's "How to Think Like Your Opponent in Chess"

"How to Think Like Your Opponent in Chess": in the past, this - or more precisely, the lack of doing this - was a major hole in my thinking. This fact was exposed during the process of analyzing my own games, and led to developing a more structured thinking process, including explicitly recognizing the need to falsify your candidate moves.

In this Chess.com video, which is one of a new series (under the header "Why You Should Always Ask What Your Opponent Is Up To"), Tatev Abrahamyan first picks a game of Nimzovich's and looks at some key points. She emphasizes the fact that the process of thinking like your opponent - in other words, about what your opponent is planning to do - is not just about avoiding tactical blunders, but also about playing the most effective moves. In some cases, this will mean moving to prevent your opponent's idea first, rather than directly pursuing your own plans.

Her narration is on point, although occasionally a little too rapid. For instance, in the two places she suggests that you pause to think about what Nimzovich (Black) should do in the first game example, she then immediately tells you the move played before you can move to pause the video. In the second game example (see below), though, she gives enough time to pause if you are alert.

The second example is from IM Anna Zatonskih - GM Marie Sebag (2019 Cairns Cup). The turning point comes in a surprise tactic by White just out of the opening, a temporary knight sacrifice which wins a pawn and gives Zatonskih a positionally won game. It reinforces the idea of never assuming there are no tactics in a position, even if it looks "normal", which is another repeated personal flaw in my play that was revealed during previous game analysis.

The last example game in the video is a classic one between Alekhine and Nimzovich in a French Defense. Abrahamyan looks at a critical moment where Nimzovich should have prevented a key idea of Alekhine's and shares some specific ideas about minor piece positioning in the structure, along with a more general lesson about being able to take your time in the absence of forcing threats from your opponent. Alekhine as White establishes a complete bind and can then improve the position at his leisure. (This game is where the famous "Alekhine's Gun" formation appears.)

As with most good instructive material in chess, there's not just one lesson to be learned from the video. I found the interplay of ideas in the first Nimzovich game, particularly regarding when it is OK to move the g- and h-pawns in front of the king, and how to blockade your opponent (a classic Nimzovich theme), particularly valuable. In the last game, seeing how Alekhine applied the strategic bind and then exercised patience and seemingly small moves to win by strategic zugzwang was also enlightening.

Annotated Game #212: Deceptive symmetry

Having lost my first two tournament games, I was focused on holding the line for this next game and not losing. I was therefore pleased to see my significantly higher-rated opponent head for a drawish-looking line of the Symmetrical English. That said, symmetry can sometimes be deceptive, since one side can often quickly change the character of the game in their favor.

Here my opponent varies a little, but we still end up with a symmetrical pawn structure on move 17. However, now Black's pieces are able to come alive, while I start to get myself into a cramped position; this has been a long-term tendency of mine, particularly as White. My opponent misses a chance for a clear (if small plus) by playing the wrong pawn recapture on move 20, but I then dig myself into a positional hole with my two knights on the a-file rim. Luckily I am able to recover and then find the correct blockading strategy, being happy to take a draw in the final equal position.

I think it's important to be able to recover from an 0-2 start and not get too down on yourself. I also think it's a mistake to be playing deliberately for a draw. Here that wasn't the plan from the start, even though the opening was itself drawish. So although I wobbled a bit in my play, I was satisfied that I ultimately found the right path and played according to the needs of the position.

Annotated Game #211: Patience you must have

This second-round tournament game is an excellent illustration of how a completely level position may still require patience and your full attention, in order to avoid going astray. Here, White chooses a non-critical version of the Classical Caro-Kann and by move 14 (after playing the classic ...c5 pawn break), I am in fact quite comfortable as Black.

However, succeeding in implementing the standard opening plan here doesn't bring me any grand success on the board, just easy equality. My attention then wanders and I lack focus and a deeper understanding of the position, going for an unimaginative (and ultimately losing) strategy of delivering an unnecessary check and then simply swapping pieces. My opponent does a great job of finding the refutation of this and a pretty mate at the end.

White doesn't have an obvious aggressive plan, so makes a moderately useful move while waiting to see where Black commits the king.} Qc7 {still keeping the options open while developing to a useful diagonal.} 12. c4 O-O {after my opponent's queenside expansion, now it definitely would not make sense to castle there.} 13.

Annotated Game #210: Missing the big idea

This next OTB tournament started off rather weakly - perhaps not a surprise, as it had been about two months since I had previously played seriously. The game has two notable lessons for me:
  • First, the opening mistake on move 9. It has been a tendency for me to want to "punish" opponents who deviate from book moves in the opening. In this game, I am too eager to give up the two bishops for an essentially meaningless doubling of Black's c-pawns. As a result, he has far better piece activity and I struggle to complete my development, getting unnecessarily cramped in the process.
  • Second, missing the key positional and tactical idea of pushing e3-e4. This possibility recurs a number of times and is symptomatic of a mental tendency to sometimes consider pawn structures as fixed and focus only on piece play. It becomes amusing how many times this move would have been the best, if only I had seen it.
Another useful lesson is to never give up. Despite some serious problems and pressure on my king, I was in fact given multiple ways by my higher-rated opponent to get back to at least equality. In other words, don't panic, and you may actually be able to save yourself when defending.

Another way of looking at this is to recognize the advantage of mobilizing the extra kingside pawn in the center.} 17.
