Annotated Game #334: Misery loves company

This final-round tournament game was rather miserable, contributing to a rather miserable outing overall; at least I didn't lose all of the games, which was some consolation. Again I achieve an advantage out of the opening - here, as early as move 3 - but poor thinking and evaluation of my opponent's potential threats mean I am on the ropes before the middlegame even properly starts. My opponent misses several critical continuations, but in the end is able to very effectively dominate with his pieces, while mine are ineffective. Props to him for not collapsing to the early pressure and fighting back effectively.

Annotated Game #333: When to trust an attack

This third-round tournament game highlights the attacking potential of the Colle / Stonewall Attack setup, with some spectacular tactics lurking if Black does not defend properly. Unfortunately I miss seizing my chances, first with a knight sacrifice on f7, then afterwards with a rook sac on the same square - which is in fact played, but one move too late to be decisive. My calculation and visualization challenges continue, leading to an eventual loss after sacrificing too much material, although I could have had a saving perpetual on Black's king.

Part of the problem was not trusting the initial attack enough to play into it. Even in a situation where you cannot calculate everything - which inevitably occurs at all levels - one can (and should) still evaluate the likely prospects for the attack. I am still relatively new to attacking play and therefore learning my way in such situations, which in this case called for more boldness. That said, I will also draw attention to the analysis, where after the sacrifices certain more patient prepatory moves would be necessary to seize the advantage. After not seeing immediate forcing sequences, however, I discarded the original attacking ideas. Patience in the attack is also something a lot of club players need to learn.

Annotated Game #332: If it's not in the repertoire, it must be bad (?)

This second-round game taught me another opening repertoire lesson, this time in the Advance Caro-Kann. I had never seen White's move 7 before and thought it must be bad, or at least would provide me with an edge. The most direct response, 7...a5, would indeed have been excellent if it weren't for White's 8. Bb5! with an annoying pin. This is how learning and repertoire-building take place most effectively, however: by filling in repertoire holes whenever they are discovered, and taking the time in home analysis to understand the relevant ideas and comparison positions.

In the late middlegame I finally play actively enough to put my opponent under pressure, but then did not spot variations on a winning endgame idea, which involved sacrificing a pawn to get my knight into the action decisively. An interesting game, in any case, where my opponent gets props for spotting how to take advantage of some incorrect ideas and passive moves - although he then over-pressed with moves like 19. f4, giving me the better chances in the end. This is a common theme seen by Caro-Kann players, and one reason I remain very satisfied with the opening as Black.

Book completed: Peak Mind by Amishi P. Jha, PhD

    

I recently completed Peak Mind by Amishi P. Jha, PhD. For chess improvement purposes, this falls under the category of mental cross-training; you can see particularly relevant excerpts in Training quote of the day #56 and Training quote of the day #58.

The core message of the book is valuable and essentially boils down to what is on the cover: Find Your Focus, Own Your Attention, Invest 12 Minutes a Day. For chessplayers at whatever level, there is no doubt about the benefits of increasing your ability to focus and to pay full attention to everything on the board in front of you. Mind-wandering is inevitable, as the book discusses at length in a scientific fashion, but the trick is to recognize what is going on and be able to re-channel your focus back to the present moment.

For the "12 minutes a day" part, this was the minimum effective dose (MED), determined by the author via experimentation, of mindfulness training that demonstrated a measurable positive difference in performance outcome in practitioners. She offers up a menu of three types of mental training and a suggested training plan. While this may well be an effective template, other types of mental training and mindfulness practices can also be as effective - this is not a new concept and various aspects of "mindfulness" have been touched on in previous posts. There is a reason various types of focused meditation have been integrated into martial arts practices - including modern military special forces training - for millennia: it gives the practitioner a mental edge in what Jha termed "periods of high demand", be that competition over the board, in an athletic event, or on a battlefield. The ability to calmly evaluate what is happening in real time, put aside both external and internal distractions, then effectively apply your skills and training to the situation is often the key to victory. This is in contrast to instinctually attempting to overcome a problem via the increasingly desperate application of raw strength (physical or mental), which is what fear and adrenaline do to us.

I have to say that for me the writing style falls firmly into the rather formulaic self-help category, and perhaps a majority of the book ends up being rather "fluffy", as I tend to put these things. That said, the core precepts are valid (and validated), and worth paying attention to.

Annotated Game #331: Derailing in the opening

This next first-round tournament game saw me derail as White in an unfamiliar opening. I've been learning the Colle and my opponent deviated from anything I had in my new repertoire on move 4. The principles are similar to other lines - chase the light-square Black bishop and exchange it - but it was nonetheless unfamiliar and the first time facing the position over the board. Black played well and surprised me with 8...Bd6, threatening h2, which I focused on directly opposing with 9. f4? rather than countering with 9. Qb3, which is a key idea in these types of positions. The power of a significant lead in development is then demonstrated by Black, as my opponent is able to make natural moves and achieve a major positional plus, which he then accurately leverages to collapse my position. Learning an opening the hard way can be...hard.
