Video completed: The 4...Nf6 Caro-Kann by Nigel Davies


I recently completed the FritzTrainer The 4...Nf6 Caro-Kann by GM Nigel Davies, which was published in 2016. It covers lines in both the Bronstein-Larsen (5...gxf6) and Tartakower (5...exf6) variations for Black, which is unusual, since Caro-Kann opening resources normally focus on one or the other, because of their major structural differences. The content description is copied below; there are also 16 quiz positions at the end, mostly from the Bronstein-Larsen side. In each of the lines, a full game is presented as the baseline, although certain sub-variations or ideas are demonstrated within it. There is also a separate, larger database of model games included in both variations.

As is reflected in my annotated games database attached to this blog, I've long played the Classical (4...Bf5) variation of the main line Caro-Kann. I have no intention of giving it up, but the 4...Nf6 variations are of interest both from a general improvement standpoint and for potentially expanding my personal repertoire. The position-types that result have some resemblance to familiar ones, but especially the Bronstein-Larsen requires a more dynamic, attacking approach from Black. The positional imbalances that result are also a useful way to deliberately (if more riskily) play for a win as Black, versus the normally more staid positions of the Classical variation.

Although this video set is one of the more comprehensive ones available on the topic, it still covers a lot of territory without much depth, particularly in the main line Bronstein-Larsen 6. c3, where Davies recommends ...h5 as Black's response, rather than the much more common ...Bf5. The database supports this choice, however, with ...h5 scoring significantly better. White has a large number of 6th move possibilities, as can be seen below, so this lack of depth is probably unavoidable.

I avoided the Tartakower variation when originally building my personal repertoire largely because of Korchnoi's defeat against Karpov in the world championship series while relying on it. That said, it's certainly solid and in fact underwent something of a renaissance several years after this video was published. I don't believe it's quite as trendy at the moment, but there are many current games with it and it scores significantly better than the Bronstein-Larsen, so it may be worth delving into further. If you are looking for an introduction to the modern (2017 and on) treatment of the Tartakower, this blog post by GM Max Illingworth on Chess.com may be of interest: https://www.chess.com/blog/Illingworth/the-modern-caro-kann-antidote-to-3-nc3

The learning cycle articulated

In Annotated Game #267 ("How openings are really learned") I highlighted the cycle for acquiring deeper understanding of openings and their early middlegame plans: play consistently, analyze your games, and you will inevitably expand your understanding of them step by step.

Separate but closely related to that, I recently ran across what I thought was a well-articulated (and simple) version of the broader learning cycle at Chessmood:


The full article addresses other things like the importance of mindset, but below is how they present the cycle. It's worth clarifying that the "Practice" step, in the sense we are talking about, does not mean reviewing your stored opening repertoire (or other knowledge) by yourself; rather, it is about using your chess knowledge (opening, middlegame, endgame) under actual combat conditions. Improvement via analyzing your own games then becomes an iterative process that yields concrete results over time, even if temporary setbacks occur.


The chess improvement formula

It’s quite simple.
Study -> Practice -> Fix -> (Repeat)

You learn something first.
You practice it; otherwise, you’ll forget it.
You fix the mistakes you make.
Then you learn new things, and the cycle continues.

Annotated Game #267: How openings are really learned

This final-round game illustrates several useful themes, including recent ones highlighted like the importance of playing an idea at the right time and the power (and necessity) of simple development. The mutual "??" moment on move 32 shows how time trouble was affecting my game, as I had a chance to turn things around, and played the correct move one tempo too late. 

This game is also a perfect example of a broader theme of how openings really get learned - namely, the hard way.

During the game it was clear that my opponent as White was out of his personal experience in the opening phase of a Panov variation of the Caro-Kann. This however did not stop him from finding the correct attacking setup and plan, which to be honest is not that hard for an experienced White player. In contrast, never having faced/studied the position starting on move 11, I struggled to adapt and ended up committing the sin of moving a piece multiple times in the opening to no good effect, which essentially handed my opponent the initiative and an excellent attack.

I did not feel too badly about missing the one tactic, since my opponent had simply outplayed me for most of the game, although it stung a bit. The main lesson for me was the need to keep playing consistently, analyze my games, and constantly expand my understanding of openings and early middlegame plans in that manner. Databases and references are great, but understanding comes from the actual fight on the board.

Annotated Game #266: The importance of playing an idea at the right time

I happened to get two Whites in a row and I was not unhappy, given the previous result, that this game paralleled Annotated Game #265's Symmetrical English until move 8. Black's asymmetric reaction in the center with ...e5 created an imbalance in the position which I could have reacted to with the idea of Bg5, looking to trade the now "bad" bishop off. However, I pass up several early opportunities, only to play it at a much worse time later in the game, which nearly gets the bishop trapped. A similar theme applies to my light-square bishop's back-and-forth maneuvers.

The game overall was more stressful than the previous one, with Black's space advantage and better piece activity keeping me on the ropes for much of the time, although I had a number of chances to equalize (and did so several times). Time trouble for both sides played a major role in the outcome, as well.

Annotated Game #265: The importance of a sense of danger

This second game from the tournament featured a Symmetrical English, which had a great deal of symmetry indeed, only varying on move 9. If one chooses to play as White in this way, then patience is the key to success, rather than an ability (or desire) to pursue an attacking, imbalanced game. It can be annoying when Black clearly has no experience with the opening, but can still get a good position simply by mimicking moves. However, sometimes the patient approach pays off, as in this game after Black gets impatient and presses too hard with his queen, at a time when a sense of danger was necessary.

Annotated Game #264: Lessons learned from an Exchange Caro-Kann

This next game started off my second "comeback" OTB tournament last year. My opponent was comparable in strength and we came out of the Exchange Caro-Kann opening in an equal but positionally dynamic situation. The variation I chose (6...g6) results in a structural imbalance, which in this case ended up with Black having an isolated queen pawn (IQP) position in favorable middlegame circumstances. That said, my planless and overly optimistic early middlegame play allowed White to gain a small advantage, but I hung close and eventually she was essentially forced into going for a three-time repetition to secure the draw.

It is always striking to me how analyzing your own games inevitably highlights significant lessons and insights into your play and how it can be improved. Even in cases like this, a relatively quiet, largely strategic and positional struggle, certain ideas can shine through clearly:

  • The strength of simple development and importance of optimal piece placement. I missed in various ways the effectiveness of just getting my bishop out with ...Bd7 and allowing the activation of the queen's rook; this did not happen until move 22. Another key positional idea was to retreat the dark-square bishop on move 14, which would have preserved the two bishops.
  • Immediately dissolving the tension on move 18, rather than searching for other improving moves. This urge to immediately swap pieces and resolve tension is a common feature (and drawback) of play at the Class level.
  • Missing good moves due to the calculation "horizon" effect - I stopped calculating too soon once I saw an "obvious" advantage for my opponent in a variation, without seeing additional tactical possibilities for myself.
I was nonetheless reasonably satisfied with my level of play, including the ability to recover after handing my opponent some advantage, and it's not a bad start to draw a similar-strength opponent at the start of a tournament.

Book completed: My Best Games by Victor Korchnoi (2011 edition)


I recently completed My Best Games (2011 edition) by Victor Korchnoi, which I originally started in late 2022. It took that long for me to go through the 110 games (half as White, half as Black) at a fairly regular pace, with around 20-30 minutes to review each with a physical board. As part of my training process, I normally have an annotated games collection in the study mix, ideally one that includes a player's own comments and considerations, which provides special firsthand insight into the thinking process.

This collection did not disappoint in that regard, as Korchnoi offers a number of valuable insights into chess thinking and performance, beyond specific game considerations and variations; you can see some of them in several previously posted training quotes of the day. I particularly have enjoyed going through Korchnoi's games here and in other collections, such as the My Life for Chess ChessBase video volumes, for several main reasons:

  • Korchnoi was never a chess prodigy and is an example of someone reaching the highest levels (#2 in the world) through "normal" training and hard work. Of course his career and abilities were far beyond average, but the main point is that it did not come automatically to him as a childhood gift.
  • Perhaps for that reason, he has perhaps unique observations and insights into chess performance, principles, and practical considerations - and can articulate them well.
  • While Korchnoi was extremely competitive - being known as "Victor the Terrible" at the height of his career - he also was candid about his mistakes and failings in annotations. He offers up a number of examples of where he passed up draws or played objectively weaker moves or opening setups out of curiosity, fighting spirit, and/or a simple desire for variety. This makes for more interesting chess.
  • Associated with that approach to chess, Korchnoi had one of the widest repertoires and knew how to play a large number of position types.
As with any games collection, when going over it a student needs to do work to understand it on a more personal level, and read it critically. Korchnoi is not particularly consistent in the level of his annotations, sometimes taking the time to give a short variation with a tactic as an explanation, other times simply noting a particular move would be tactically bad, meaning you have to figure out why for yourself. This of course is part of the learning process and why reviewing annotated games in an active way can be so helpful to advancing your chess, because you have to engage with the material and not just accept it.

There are the usual typos or incorrect information present in a few of the game scores and annotations, but I would say no more than around a half-dozen in the entire volume, which isn't bad; all the large game collections I've been through have them due to editorial oversight.

Annotated Game #263: A lucky draw

I'm not a big believer in luck in chess, although in practical terms it does apply in a sense to what your opponent decides to do, since that is out of your control. In this last-round game I was attempting to break the downward trend of this comeback tournament (win-draw-loss) and did well enough out of the opening, a Symmetrical English.

My opponent varied the symmetry on move 7 and I entered a line where after a number of exchanges the engine shows that it is a drawn game, which was a little disappointing for me. In addition, my opponent maintained a space advantage and some psychological pressure, which was compounded by my innacurate visualization and calculation of the transition into a rook endgame. I was simply lucky that my opponent did not spot the winning idea I allowed for her - but I will at least give myself credit for spotting it before she did and then shutting it down immediately when she missed her one chance to play for a win.

Annotated Game #262: An unhappy introduction to the Fantasy Variation

This next tournament game was an unhappy introduction for me to the Fantasy Variation of the Caro-Kann. I've had it in my repertoire for some time, but had never played it at the tournament level before, so was unable to solve the early problems at the board and went astray quickly. White chooses the most classical (and threatening) setup in response to 3...g6!? and while I correctly concluded 5...Qb6 was the correct response to White's bishop development, I was unwilling to go for the "poison pawn" on b2 as a follow-up - which is the only correct move, however. The rest of the game demonstrates the superiority of White's pieces in the face of solid-looking but erroneous play.

For chess improvers, this is a very pointed example of why regular tournament games, accompanied by analysis and refinement of your own play and repertoire, is a necessary and virtuous cycle. You are much more likely to recognize, remember and respond to situations on the board that are familiar firsthand as well as studied, rather than simply memorized. This is one of the reasons chessplayers typically lose more often with a new opening, but then accumulate experience and start winning more. I look forward to establishing a more effective battle rhythm.

Unfortunately this was about all I remembered about it.} 4. Nc3 Bg7 5. Be3 Qb6 {I thought for some time on this and according to the database it's the best move. Black takes advantage of the missing bishop from the queenside and pressures d4.} 6. Qd2 {unfortunately I really had no idea what to do by this point. Taking on b2 is necessary, but I eventually went for the "safer" text move.} e6 $2 {unfortunately this move in fact puts Black in considerable jeopardy.} 7. O-O-O {White already has a near-winning advantage here, which at least makes me feel less bad about the subsequent blunder on move 9. The queen is doing nothing useful anymore on b6 and Black is behind in development, with king safety starting to become a problem.} Nd7 8. h4 {my opponent clearly understands how to play this type of position, while I do not. This is a natural attacking plan, now that the king is on the opposite wing. Now comes the blunder on move 9, after a futile queen move; however, the engine already gives White a +2 advantage.} (8. Qd3) 8... Qc7 9. h5 b5 $2 {the main thinking process lesson from this move was ignoring the ability of White to change the "static" central structure, as the Black c-pawn is now positionally overloaded. I also partly hallucinated that a White Nb5 would be unprotected - in fact the Bf1 does that.} 10. exd5 $1 cxd5 {the other recapture is slightly better according to the engine, but I couldn't bring myself to open the file to my uncastled king.} 11. Nxb5 {after this and the follow-up move the game is essentially over, although I had (very small) hopes of a swindle based on pinning the Qd2 against the king, or some sort of cheapo mate on b2.} Qb6 12.

Annotated Game #261: Let's be realistic

The next tournament game following my return to OTB chess last year had me faced with a completely new response by Black (to me) in the English Four Knights (4...g6). I responded reasonably well and found (a bit late) the key to the position, which was advancing d4-d5 before Black blocked it. By move 10 I have a pleasant positional plus as a result. However, by move 22 this is gone and the game is completely level, with Black having some initiative. 

It's worth looking at how that happened in the analysis, but another main takeaway from this game is that I was properly realistic about the situation and did not foolishly try to recapture the lost advantage. Black pressed a bit at the end but had nowhere to go, so the game correctly ended in a draw. Sometimes it's easy to fool yourself into trying to win, when the position dictates otherwise. Psychologically this often happens, and we see a game trajectory where someone gets an advantage, spoils it, then either does not realize it or desperately tries to win regardless, which can easily lead instead to a loss. Accepting reality is the better way.

Nf3 Nc6 4. e3 {my opponent appeared somewhat unfamiliar with the opening, given some pauses, and now played something I hadn't faced before.} g6 5. d4 {the usual reaction for White to a move that does not pose a challenge in the center.} exd4 {choosing to liquidate then play against the center} 6. exd4 {the normal choice for White to recapture, giving him a bigger center. Unlike in a normal KID setup, Black no longer has the e-pawn to challenge it.} Bg7 7. Be2 {played without thinking enough about the position, as a "standard" move.} (7. d5 {immediately is a better idea, to seize the central space and prevent Black from occupying the square.}) 7... O-O (7... d5 8. Bg5 Ne7 $11) 8. d5 {I was a little uncertain about playing this, but saw the prospect of perhaps having to play an unenticing IQP game as being worse, if Black gets in ...d5. The engines agree it is the correct idea.} Nb8 {this seems less useful than the alternative ...Ne7} 9.

Nxf5 {this gives Black too much play and justifies the queen move. Better was to patiently increase the pressure.} (14. f3 $5 {is ugly but effective, controlling the key e4 square. It looks wrong to block the Be2 in, but it was going nowhere useful on the d1-h5 diagonal anyway. Meanwhile, Black cannot take advantage of the a7-g1 diagonal's opening.}) 14... Qxf5 $14 15.

Basically the queen needs to be kicked out of the center before anything else can be accomplished.} Qg4 {this gives me the move h3 for free.} 16. h3 Qd7 {unfortunately, now I was unsuccessful in coming up with any meaningful plan, beyond vague notions of dominating the e-file.

Kf1 Qf5 {I had missed this move, which by protecting the Re4 removes some potential tactical ideas for White. I looked at the Black queenside pawns, but decided there were too many downsides to attempted pawn snatching with either the Be3 or after Qa5. The engine agrees.} 25. Re2 {playing without a real plan, other than to continue covering squares and maybe rearrange the pieces a bit. Here, however, the lack of ambition is entirely correct.} Re5 26.

More pop culture chess imagery - imposter syndrome and getting ahead of 99% of people

I randomly ran across the below recently, which are some more good examples of pop culture chess imagery - which is often wrong or misleading, so maybe not good.

Visual by Harsh Darji - artist's Instagram

This one I originally encountered in the article 10 Powerful Visuals You Need To See Before You Enter 2024 on Medium.com. It has a superficially valid chess metaphor: the queen looking at a mirror and seeing a pawn, as an illustration of "imposter syndrome" - but it seems to me that it doesn't really work. Visually there's the fact that it depicts a White queen is looking at a Black pawn, which doesn't make much sense in a chess context - switching sides is not an option for pawn promotion. There's also the overall squishiness about the imposter syndrome concept, so its depiction isn't necessarily clear.

The next one is a stock photo used to head the Medium.com article by Alexandru Lazar entitled Ten Habits that will get you ahead of 99% of people. You can find it various places on the internet, but the imagery is clear: a White king on a bare board knocking over his counterpart, normally done when taking a piece. A powerful-looking visual intended to convey supremacy - but in fact an illegal move in a position that is a forced draw. Authors who use faulty chess imagery like this tend to lose credibility instantly, at least with chessplayers, so here's a plea for people to avoid doing that.
