Go up one level in this thread


I do not know whether tiger uses other learning than book.
If it does, it would not be new. Genius3 already did something (it
never repeats its games).

fritz3 did some hashtable learning which all can be cleaned
by setting the level to a certain depth (say 10 ply).

Personally i think that preventing to lose in the
same way is very smart.

double games are indeed not counted. This is something we
both agree on for this match. I find it weird that SSDF
accepted it from Rebel8 though.
