Probably the only commercial engine which will make it into my “Hall Of Fame”. Nearly all commercial engine developers claim to have a “human like” chess engine. But what is “human like”? I’d say an engine which plays the same moves as a human. Some time ago I did some experiments and at the end I created a testsuit with 100 positions. All played by Bobby Fischer, and all commented as a (very) good move by himself. I only took positions where several moves are possible, maybe even better moves, no tactical traps, plain positional choices.
After testing some different methods with different positions (over 2000) I can say that always the same engines where on the top, so I think this test is a good method to find out which of the engines play a little like Bobby Fischer. I planned to create similar tests for other Players, but I wasn’t able to find good sources like Fischers 60 memorial games. So the “Fischer Test” will probably remain unique.
Gandalf 6 was the engine which found most of Fischer recommended moves, and it was also the engine which played most Fischer moves when I tested whole games.
69% matching moves is quite impressing. I know some guys who would now assume that Gandalf 6 is a clone of Bobby Fischer :)
