Positional Move Position

White to move?
How long does it take for your chess engine to find 17. Bc4 !?
This is the only move which can give White any chances of winning, other moves 17. Nxf6 or 17. Be3 only simplifies the position to a dead draw position.

Rybka found it right away and then discarded it only to find it again at 56 seconds

Thinker found it, but we have no clue how long it took, since Thinker is mum about his thinking.

Re: Positional Move Position

Post by Dann Corbit »

Arasan was fast, but the score is not good (-1/2 pawn). I did not check carefully, but I suspect that the plan is wrong:

Re: Positional Move Position

Post by LaurenceChen »

Thanks for the replies. It took me 5 hours of analysis to find this move. The resulting position is lost for Black. Black has an uphill struggle to find a draw. Funny that the engines give a negative score, that is, the engines believe that the position is favorable for Black, but, it is not. White has a very strong pull in the resulting position after exchanges. Black is busted.
