Subject: How many programs can find the drawish move 26.h3!

Author: Jorge Pichard

In the Second game Kasparov was very upset at the board soon after playing
(diagram) 25...Qa1+. He realized a few moves later that White could force him to
take a perpetual check draw with a surprising queen sacrifice. In the press
conference he said that he thought he had a forced win with the queen check, but
that in hindsight 25...f4 would have been stronger.


Junior co-programmer Amir Ban quotes someone from Kasparov's team as saying
afterwards that 25...f4 26.h3! was also a draw. We can't be sure yet what Junior
would have played. My DJ 7 wants to play 26.Nf1, which would allow black a very
strong attack after 26...e3.



Fritz 8 and Chess Tiger 15 both changed from 26.h3! to h4?! is 26.h4?! a better
move here?
