A Sample Coaching Game with a Student

(Part 7, final) 


Below is a transcript from an actual coaching game that shows the richness of the ongoing discussion (literally on each move) between coach and student.  A total of over 250 messages were exchanged to discuss important chess principles, key strategies and considerations, specific moves and how they all fit together, share relevant resources, etc.

The transcript is laid out in a series of blog posts, each covering a portion of the game with the relevant diagrams and discussions.  Context is re-established at the start of each part.


Legend (on how to read the discussion and follow the unfolding chess game):

[bold, larger font, cyan highlight] : the most recent move, based on the preceding discussion

[bold, dark green] : broadly valid (beyond this particular game) chess principles and related advice

white’s (coach’s) comments follow the letter “V”, while black’s (student’s) comments follow the letter “F”.

[ Continuing below after white's move 54.f5+ ]


V: The theme of 54.f5+ is a temporary pawn sacrifice in order to gain access to an important square. That theme is often seen in master-level games at the middle game phase, where pieces jockey for active positions. In the endgame, such as here, it likely leads to a zugzwang for black on the very next move. Are you familiar with zugzwang as a term and as an idea often applied in endgames (but not only)?

F: Yes, very familiar with zugzwang.

F: Ironic timing of chess.com posting this video on zugzwang. http://youtu.be/6SQKVbbtsfg

 

[54…gxf5+ 55.Kf4]

 

V: It's a common theme, especially in endgames, and it can be even more spectacular in middle games. There are a few famous games I've seen where it was masterfully used in middle games. I'll see if I can track those and send to you.

V: Check out those games with middlegame zugzwang (I knew the Nimzowitch game, but the other two are fascinating too): http://en.wikipedia.org/wiki/Immortal_Zugzwang_Game

V: Here's another recent example I remember well -- in the final position white has plenty of legal moves and the position seems superficially balanced, but indeed every move by white loses immediately. A masterful showing of Aronian: http://www.chessgames.com/perl/chessgame?gid=1556261

F: Thanks for the good game and the coaching.

V: Thank you for playing! This was, as before, a game that could have gone both ways. You held the advantage for a bit after the opening, and white only managed to turn things around with the activation of the light bishop (via h3), to which black didn't find a good response. In all honesty, I also didn't at first realize the power of this idea for the bishop activation: I did it because it was the best I could see, and I was hoping that it would stabilize the game for white, while in reality it paid off even more handsomely.

V: As far as continuing the coaching, it will depend on your goals and desire for it. I am available, and it has been a pleasure for me. It has also been a nice challenge, technically in terms of finding and explaining strong moves and ideas -- you're a relatively strong player, so this is important as part of your learning. So I wish to thank you too for the value you've provided to this experience!
