  1. Much depends on how you tweak the parameters of the chess engine. Fritz defaults to a high contempt value while Rybka defaults to a low contempt value… which is why Fritz seems a little more tactical and Rybka a little more positional… but tweak the values and that should change. I haven’t experimented too much because I find the dichotomy useful. 🙂

    If you had to rate their default playing styles from the most tactical to the most positional, how would you arrange the list of the above engines?

    If that seems like a silly question, let me ask a slightly different one: which of these are the top 3 strong positional engines in increasing order? I was just wondering, that’s all, and I have no idea myself. But am very curious as to what you think.

    Much thanks in advance.
