Tiger Wins Again - Match is Tied!
Match is tied at 2-2.
The fifth 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 Tiger, winning the second game in a row to tie the match at 2-2.
The Chigorin defense opening was played evenly by both sides. The game seemed
to turn favor white after 22. h5. That move that set the stage for the white
bishop to control the long diagonal a1-h8. Black could never really maneuver
very well once that diagonal opened up.
With this win, Tiger's ties Crafty at 2-2. Crafty stunned Tiger by winning the
first two games of the match. The third game ended in a draw.
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 6 is underway.
