If so, at what depth does it find Bxh6? I ran it on a P6/200 and it finds it in ply 10, in a minute, at about +1. I left it for a couple of hours and when I came back it was failing high in ply 14 at +1.67. Perhaps it found 4. Bd3 at that point, I don't know, since I stopped it in order to answer your questions. Ferret can be a little speculative but it tends to speculate more in the center. I'm not real big on the Bxh6 thing, and perhaps I am wrong. When it wants to play a move like that it typically wins, because it finds material compensation. It won't play that move as often as it should, and setting the sac up against the program is a good way to beat it, as well. I would like to know if othe programs are really that much better at seeing through king stuff than mine is, or whether they are just flat out going for it. bruce
