Ah, the 2400, yes. A friend of mine and me started an opening book project, a
year or so ago. Bookup style backsolving of massive pgn. The hypothesis was that
with a standard engine and a superbook, you could get a top rating. Sort of CAP,
but much more positions (I think). I said the proof is in the pudding, and I'll
make the software. And we started experimenting, for over a year which was
pretty exciting in the beginning. Jan Kaan still maintains the real superbook. I
sort of lost interest and we came to an "agreement". Still, using Crafty he has
a higher rating than normal for the hardware he is on. From those days is the
2400.

Anyway I'd love to play Amateur, going to try it rigth now :)
