Go up one level in this thread


Thanks Vasik.  First I want to congratulate you on a really fantastic effort
with Rybka.  It is really the first engine that I think plays with some
intelligence instead of using brute strength.  I am not quite sure how you did
it but it seems that the big difference between Rybka and other engines is that
Rybka identifies the critical lines and then searches only those critical lines
extremely deeply.  This causes it to outsearch even much more powerful machines
and gives it this incredible strength.  If you remember the tournament on
Playchess where humans were allowed to use computers to choose the paths.  I
think it was evident from the loss of dramatically stronger hardware (Hydra)
that sometimes even a less than IM level chess player, can have enough chess
knowledge to guide the engines into the most promising lines.  By having the
engine probe only the critical lines and avoid the other "chatter" you have a
huge multiplying effect on the power of the hardware.  If you somehow manage to
do the same for endings (I see no reason why you shouldn't be able to) I think
the ramifications will be immense.  We might have to then do tournaments with
handicaps to make it fair ;)
