Re: My troubles with Linux Ubuntu 8.04

After listening to so many people and his hoopla about Linux, I decided to give it a try. So I downloaded it, installed in a partition taking only 30%v of my HD -a common sense precaution- and begun to use it. But, here comes the problem. If you are not a bloody computer geek, you does not know eve...

Re: stalemate detection in quiescence search

OK, I see. The scores are about +4, to describe the advantage of B+P, plus possible passer bonuses. It would probably sufficient to only test for stalemate (if there are no captures) in positions that have a bare King, or King + Pawns where all Pawns are blocked. Exactly. That solved it in my engin...

Re: Rybka is made out of People! (serious problem exposed)

Why do you care enough to post a reply? Do you believe that you are somehow defending Rybka, and further let us try to figure out why someone would feel that they need to defend Rybka. I think this is just human nature. I have a similar question as Bill. He asks "Who cares?" and I ask "Why care?". ...

Re: 2008 ACCA President's Compter Chess Tournament

Assuming you mean 'Western hemisphere' in stead of Eastern: The Netherlands has some Islands in the Carribean, and I have Dutch Citizenship. Does that mean I can register, or is the citizenship not enough, and does one actually have to live in that hemisphere? Your Princess is Argentinian, so you s...

Re: How many engines consider this positional sacrifice

{snip} Gee... I never expected Gaviota to solve both. I think that the mobility terms that Gaviota heavily depends on are critical in this position. Miguel You never know which program will uncork a really interesting move. I find that gaviota ans quark both have some fun moves in their arsenal and...

Re: Chess theory vs. search function !

My assertion was about chess engines only. Humans know better the chess theory but they can't search too deeply.This handicap will never be annihilated.Contrary to humans the chess engines are very fast searchers but with a very primitive evaluation function ( most of them ). Remain a lot of possib...

Re: How many engines consider this positional sacrifice

1 d5!? [d]r1bq1rk1/p3nppp/1p2p3/8/3P4/1QN2N2/PP2RPPP/R5K1 w - - 0 0[d] This position is considered in Silman's book, reassess your chess. The white d pawn is terrible and the black bishop is about to get real active. So white sacs the pawn, and in exchange gets a shletered spot for his knight on d4...
