Firstly what I wanted to test is: are the the results of ponder _on and ponder_off tournaments are comparable. And it's very likely to me they are. If you you look in the results in my games archive you will easily find that Crafty's outcoming in the ponder_off round is probably randomnly. There isn't any evidence that Crafty is playing stronger with ponder_off. I assume _every_ program is playing stronger with ponder_on. Secondly Crafty wasn't the only program envolved in this test. The outcoming of all other program are nearly the same in both tournaments . Maybe _all_ other authors of the other programs have implemented ponder_off time management in a similar rudimentary way as it has done in Crafty. But this seems very unlikely to me. So what to do next to test the effect of ponder_on? I don't know yet. To do another test with other engines, different time controls, more/less games seems to be the wrong way because I don't know anything about the time management in the other programs. To use special versions of the programs which are allways or never ponder are possibly the way to do such a test. Volker >I agree, there is very little data to suggest that, except Pittlik's data.
