Game 3 Ends in a Draw!
Crafty is leading the match 2-0.
The third 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, ended in
a draw.
Tiger came out of the opening slightly better, reaching it best evaluation of
the day with +1.16 on move 40. Crafty ended the pressure with 43. …Rc1. The
balance of the game was uneventful and both sides agreed to the draw.
With this draw, Crafty maintains 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 4 will be underway
soon.
