The title of this post is meant to stimulate your interest by being a bit mysterious. Let me explain...
Muller and Lamprecht's excellent Fundamental Chess Endings gives this position as 4.16:
White to move
From Loginov-Loskutov 1996
Any serious chess player will recall playing positions similar to this one and how difficult it can be to win them even though a clear piece up.
So what are my "three points?"
1. I recently did a post on "What is a "Better" Position?" At a glance, Black is obviously "much" better, but is the position "won" for him? The conclusion of this game might make you rethink this terminology.
2. The end of the game will provide a position that all of us must know 100 percent stone cold in order to avoid endless heartache and tears for the rest of our careers.
3. It's been awhile since I did one of my Homer Nods posts ("...and yet I also become annoyed whenever the great Homer nods off." Horace, Ars Poetica). Even very good chess players sometimes play very bad chess, and examples of this can serve to encourage the rest of us, to say that maybe we shouldn't beat ourselves up over our own little blunders. In this case Black was an International Master trying to post a nice upset over a Grandmaster, and an IM should probably be able to win almost 100 percent of the time from this position.
Enough talk, let's go to the record. For convenience, here is the position again:
The first few moves are obvious: 1. Kh6 Bd3 2. Kg7 Bg6 3. f4 Kb2 4. Kf6 (if 4. f5 Bxf5 5. Kxf7 Kc3 -+) Kc3 5. f5 (diagram):
and now 5. ...Bh5 wins (and working out the variations is great exercise), but even if it only drew, I think that the choices are so limited most of us would play it right away; instead, 5. ... Kd4?? 6. fxg6 fxg6 7. Kg7 1-0 because after 7. ...Ke5 8. Kxh7 Kf5 9. Kh6:
Mutual zugzwang! Whoever is to move loses. Learn it, use it, LIVE IT! When pawns are locked in an ending, plan and scheme to get this position--with the right player to move, of course.
Going back to the first diagram, is there any way you would have thought an IM playing Black would be resigning after seven moves? Don't let it happen to you!
