• Pro Deo 2.7 Chess

I just ran across this Nezhmetdinov game where he sacrifices his queen for two minor pieces. (12.QxBf6) Apparently, it's one of those intuitive sacs where all the variations can't be figured out over the board.

Nezh even claimed that he wasn't able to calculate everything out in post-game analysis. But Nezh plays it anyway and wins the game. (The strategic basis for the sacrifice is Black's backward development and the weakness of the black squares around his king.)So I plugged the position into a few engines, including Pro Deo 1.6 Tal, to see what would happen. Of course, Rybka and Stockfish prefer the mundane 12.Qh6, but Pro Deo Tal plays the sac! (I should point out that Pro Deo Tal isn't very strong, maybe 2000 or so. One might be able to tweak the personality settings and get the strength up to around 2500, but even then it's not going to tear up other engines.

But I think it would give any normal person a good game. Also note that the evaluations for the Tal setting are way optimistic, so this can't be used for analysis - Only for fun! )Rybka 2.3.2 best move: 12.Qh6 - eval +0.11sac eval: -0.86Stockfish 1.7.1 best move: 12.Qh6 - eval +0.28sac eval: -1.53Pro Deo 1.6 (normal) best move: 12.Qh6 - eval +0.33sac eval: -0.76Pro Deo 1.6 (Tal) best move: 12.QxBf6! - eval +1.13.

Super Nezh by Alex Pishkin tells the story.This is the note after black's eleventh move:'Long ago this position was known to be drawn because White could choose between 12.Qh6 Bg7 13.Qh4 Bf6 with a repetition of moves, or 13.Qg5 Qxg5 14.Bxg5 Nxb3 15.axb3 Bxc3 with a drawn endgame.

If 12.Qg3 or 12.Qf4, black would reply 12.Qxc3!.Chernikov was sure that his opponent wanted to rest that day. Therefore he quietly strolled about in the tournament hall. Meanwhile time went on and Nezh continued to think. Everyone was puzzled 'what was Rashid Gibyatovich thinking about,' there was no avoiding a draw.

At last a boy, out of breathe, ran up to Chernikov and said: 'Dyadya, a Queen was sacrificed to you!' The game goes on to mention various improvements for black including 14.

And say that Nezh did not fear playing into these positions again. Black would have a lot to contend with in a live game.It's not necessarily sound. It's just one player's unwillingness to agree to a dull draw so early, even at the risk of losing!

Being over the board inspiration makes it ten times more admirable as well!Here is one final quote from the book:'The game produced such an impression on the many participants of the championship team that none of them presented their games to the judges for the beauty prize - it was guaranteed in advance to Nezh.' Originally posted by greenpawn34A very inspiring game. That one made a deep impression me.If only some of the other masterpieces in that book had madethe same impression I might have been a good player. 🙁Sorry for the hijack - please continue.I don't mind the hijack at all. I looked the game up. (One of these days I'll go through that book!
