Prof. Ken Chen (5 dan, GO INTELLECT) evaluates a 9x9 Go position, in which both programs passed but claimed to have won. Referee Jonathan Schaeffer (checkers: CHINOOK/ chess: PHOENIX) and Stefan Meyer-Kahlen (chess: SHREDDER) are impressed, that Go could be so sophisticated even on the small board.
Prof. Chen Zhixing with HANDTALK (pedecessor of GOEMATE). Nearly undefeated winner in the first three FOST Cup tournaments 1995, 1996 and 1997 in Japan, HANDTALK surely was one of the strongest and best known Go programs of the 20th century. Coded in assembly it plays so fast that Prof. Chen didn´t consider to implement any time controls when attending a tournament - until in the 3rd FOST-Cup Handtalk lost a game on time against DARREN, a very weak program which just did put lots of unsettled groups on the board, forcing Handtalk to do a lot of reading.
