LG 2000 2.7 vs. YACE

[Al Levine]

Geschrieben von: / Posted by: Al Levine at 09 June 2000 19:33:10:
These games were played on a PIII 450 machine with 128mb RAM. Book on, ponder off, time control of game in 10 minutes. Final score LG:7.5 YACE:3.5, but this shows in my opinion a great deal of promise for the new engine. Games are shown below.
