Re: understanding the knight bishop mate

There are seven winning moves four of which lead to mate in 33 and the other three lead to mate in 34. Fruit prefers Bg4, Ba4 & Be8 (mate in 34) before finally settling on Bh3 (mate in 33) after 2 mins 37 secs. My hardware is quite primitive by todays standards though. I would like to install the S...

Re: question to Prof Hyatt regarding milov vs rybka

for arguments sake, let us say that removing the f7 pawn made the game more volatile. but since removing the f7 pawn at super gm level is almost inevitably a loss for the handicapped side then if a computer can consistently draw such a position against 2700 elo players while we would have no way of ...

Re: question to Prof Hyatt regarding milov vs rybka

you said before that 14 games by hydra against humans is not enough to establish a 3000 elo rating. If Mr kaufman wanted to prove his rybka was better than the best human how many pawn handicap games would he need to draw against 2700 elp players before it could be reasonably assumed that it was.

Re: question to Prof Hyatt regarding milov vs rybka

since a pawn handicap at the super-GM level, is almost winning, does it follow that if a computer program with a pawn handicap can draw consistently against a super-GM then it can claim to have a higher elo than all humans (even if from a handicap match we do not know what the elo would be)

Re: question to Prof Hyatt regarding milov vs rybka

if you know some ones elo score you can predict percentage score against different opponents. based on tests he did with rybka he found the exchange handicap worth about 400 elo points. milov elo is about 3700, so if the match would have been a 4 4 tie then its elo level would have been 3100 as it w...

question to Prof Hyatt is Mr kaufman's method a reliable one

to see if rybka can come up with better positions than a gm http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?dln=91016;pid=98159 .. I think that there is a fairly good way to test the hypothesis that doesn't require a new interface or engine. First, we make a version of Rybka with only tiny ev...
