There is a limit - yes. I actually forgot how large exactly (and cannot look it up at this moment) - the 30000 might well be correct, although I thought it was 10000. It can be enlarged by some obscure commands - which I cannot look up either at the moment. Perhaps you already have the limit enlarged? Didn't I give you an explanation by mail how to do it some time ago? Do you remember José Luis Jiménez? He should be able to explain it to you. IIRC I implemented it especially for him and for you. I myself have done most of my tests with learning disabled, so I never needed that many positions. I fear, that the positional learning will not help that much in practice. But it helped against the infamous Mercilious (sp?) attack on ICC, where Yace could lose very fast many games in a row against a human. Also, Mogens Larsen had reported one case agains Gandalf, where a lost variation was draw the next time, and a critical move was avoided. Both opponents had in common, that they always tried hard, to repeat a winning variation. At that time, Yace had no book learning. That should take care of such a situation, too, and in practice might be more useful. But I really have never tested carefully, how much the learning features help. Cheers, Dieter
