Game 2
Crafty Wins Game 2 in Another Upset!
Crafty is leading the match 2-0.
The second game of the Frank J. Byrne Memorial Computer Chess Challenge pitting
the world's best freely available commercial computer chess program -- Chess
Tiger v14 by Christophe Theron against the world's best freely available
non-commercial computer chess program - Crafty v18.15 by Robert Hyatt, was won
by Crafty in yet another upset. Crafty again came out of the opening relatively
unscathed and played strong moves throughout the game.
Tiger played a suspect move 17. ...Ke7 that just didn't look right to this
amateur's eye. Several moves later Crafty played the freeing 23. e4. By move
24, both sides favored Crafty's position with an ~ 1.3 to 1.5. Tiger's position
deteriorated further when it forced to exchange a rook for a bishop and a pawn
to prevent further losses at move with 33. ...Rxd4. Tiger search depth is
averaging in the 15-17 ply range. Crafty had a few searches that were only in
the 11-13 ply range with the more recent searches in the 14-16 ply range.
With this win, Crafty holds a surprising 2-0 lead over Tiger. However the match
is not over yet and Tiger still has a lot of chances to make up the lost ground.
Like the days of yore, it is the first program to win 10 games and the program
must have a margin of victory of 2 games. A winning score could be 10-8 or
21-19 it all depends on how the games go. Draws do not count - it just wins
that count.
The match is being held just outside of Philadelphia. Game 3 us now underway as
both participants agreed to play two games today. --> Don't you love computers

Tiger v14 by Christophe Theron against the world's best freely available
