I am very impressed by the speed of your slow PII333 Mhz,
Deep Fritz6(the first program that I tried) needed a long time to find 7...g6

It seems that your pII333 mhz is more than 30 times faster than my A1000

Crafty18.15 also needs more than 2 seconds to converge to g6
Yace another program that I tried needed few minutes(yace was slowed down bya
significant factor but it ran most of the time before finding g6 in normal
speed.

7...Ke6 is a move of a lot of chess programs(see analysis).
I did not analyze if it is losing.

Based on some analysis the losing move in the game seems to be Kb2 and black has
probably a win with another move like Qe5.
