The lack of knowledge is real, not apparent :))) I am well aware of it, and no I don't intend to leave it that way forever. About CCC sure, time will tell. I am a bit stressed because of the imminent release so I was not too happy not to find mcuh help when I needed it. Next week after version 1.0 is out, things will be more quiet. >Anyway, I used the CB GUI as the "arena" (pun intended) (wishing to find out if >Fruit would run there; it did, splendidly so).

Yes Fruit is not only stupid, but slow as well. It takes a lot of time to compute very little. With the eval features as they are, it should be twice as fast. I don't optimise that because I intend to change the eval a lot anyway (but not for version 1.0). Also Fruit is designed for longer time controls; maybe it gets crushed a little less in say 20 0?
