I saw the evaluations.

Search depth, branching factor... Crafty's search and evaluation hasn't changed
much in the recent years.

How much improvement? 1% speedup? 2% speedup? 5% speedup? But the same search
and evaluation I guess.


>Did you test with own books and not with Fritz8.ctg?

I don't think it will matter. You use your own books to direct the engine into
positions it plays well. Against Crafty, Falcon has no problems in any kind of
position. (This is not true for Junior for example. In the last test, Falcon
beat Junior 4.5-1.5, but I don't think this difference of strength will hold
true if I test Junior using its tournament book.)
