Human like chess engines? The Fischer Test

Post by Alexander Schmidt »

Which engine plays the most human like chess? This question was asked often here. 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 plays a little like Bobby Fischer.

I plan to create a similar testsuite by other players to see if the same engines are on the top or if it is possible to say engine x plays like Fischer, engine y like Karpov.

For now I can show the first results:

69% matching moves is quite impressing, remember, all positions have several posibilities with similar score.

Any ideas for other "Fischer style engines"?

Your test is worthless if we don't see your testsuit!
