White to Move and Win

World Championship candidate Gelfand missed a cool win here. Can you find it?

Chess is Hard

I was going to post earlier this week about where my opponent missed a win in his pawn up endgame at the last DC Chess League match. I actually was not able to come up with any definitive conclusions, so I'm just posting the game with a few notes. I'd be interested to see any thoughts on where white may have gone wrong. Dig in:

Long Night at the Office

What is the best move for white?

Last night's DC Chess League match was a home game, so it was literally at the Office. I looked up my opponent, Andrew Samuelson, before the game and found some improvements on his previous games in the database. Unfortunately, his improvement came on move 5 and I started killing lots of clock time on mediocre moves. After I played 14... b6?, reaching the diagram above, the position became critical. Once the opponent fixed my weakness with 15. Ra6! I realized that I was going to lose the a-pawn by force because while can quickly get three pieces to the a-file.

Somewhat to my surprise, the game still had 57 moves left at this point, but I'm still in the early stages of figuring out just what was going on. Stay tuned.

I Should Make All My Classes Watch This

D'Angelo manages to teach the whole game in three minutes. I wish I could do that.

Missed This in a Blitz Game

I managed to win this one anyway, but it was a shame to have missed a nice tactic for black here. You can post a solution in the comments.

Combining Work and Pleasure

Over the winter I worked on coming up with a lot of lessons for students who had been doing chess for at least a couple of semesters already. One of these lessons was inspired by the famous game Polugaevsky-Tal, where the great world champion was undone by an inspired performance (http://www.chessgames.com/perl/chessgame?gid=1111871 ). Polugaevsky claimed afterwards that the position after move 25 of that game was on his analysis board the day before. When I turned this game into a lesson, I knew it was too long for one class period, so I found a game where black fell into the mating attack instead of almost managing to defend like Tal did.

While unwinding last night I played a blitz game on ICC against GM Suat Atalik, the number two player from Turkey. Previously my ICC record against him was +1, -7, =3, so my expectations weren't too high. He took the game into one of his tournament openings, the Semi-Tarrasch defense, the same line as my Polugaevsky-Tal lesson. I actually forgot to play one move from the opening, giving me a slightly worse version of Polugaevsky's attack. With what turned out to be one inconsequential rook move missing for each side, GM Atalik and I followed my lesson plan perfectly. He even made the same mistake that I had inserted into my lesson plan to allow a quick mate.

Next time I teach this lesson it will be my game, instead of a GM game, but otherwise it will be basically unchanged. Enjoy:

Guest Column

My Silver Knights coworker and the highest scoring member of our Amateur East team, Justin Burgess was kind enough to annotate one of his games from that event. Justin had black and his 17th move belongs in tactics books.
