notyetagm: (VAR) Position after 20 ... c6-c5!:
 click for larger viewKasparov was very upset with himself after this short draw when he was shown this continuaation. The tactical point that Kasparov missed(!) is that the Black c5-pawn is taboo since the White b4-pawn must <BLOCK> the b-file. That is, 21 b4xc5?? loses to 21 ... h8-b8, <PINNING> the White b2-bishop to the b1-mating focal point along the -newly- opened b-file. (VAR) Position after 21 b4xc5?? h8-b8:
 click for larger viewSo after 20 ... c6-c5!, White would lose his b4-pawn and Kasparov would get to play the endgame with an extra(!) passed pawn. Kasparov could then play on and on and on in that position, since he would have virtually zero chance of losing and one mistake by White could cost him the full point. |
