I recall Peter Kappler a computer scientist residing in Austin, Texas USA, who was also a strong A player in the United States Chess Federation , stating that central pawn duos were evaluated separately by all evaluation functions that were worth their salt.
The following game played at the internet chess club hosted in the United States is an excellent example of why.
Pozarek decided to disconnect and forfeit rather than resign like a gentleman in the following position. He was apparently very afraid of Black's passed a pawn while not giving any value to the his own passed pawn duo at d5 and e5.
Black would probably try Bb3, clearing the a file for the advance of his a pawn, in the diagrammed position and Pozarek would play the natural Bf5 check pushing the Black King to f7 when the pawn advance d6 would be the strongest move.
Pozarek, quit by disconnection because he did not notice the drawing deflection resource Bg6 ! The Bishop is immune to capture, otherwise the d pawn will queen. Moves like this are also called attraction sacrifices in this case attracting the King away from the square of the pawn!
This article rings some bells. My son knew Lori Balkum's son who was a tall, very bright kid with a nasty edge sometimes, but this is true of most testosterone charged adolescents! Alexander played a truth seeker named Chris Land who was a self deprecating genius. Always criticizing his own thinking despite the fact the dude was 2300 USCF!!
ReplyDeleteIf I recall lawyer Jeff Gelb and Chris were adversaries who had some epic encounters. Both very good guys!!
