Re: SEE on non-capture moves in main search

For the non-capturing moves after the hash move and killers, history move ordering performs better than no move ordering, as expected. But trying to refine this by using SEE values does not work. I have tried to sort the moves into two groups, first searching non-captures with SEE value zero ordere...

Re: so what is a fair GM handicap vs Rybka?

Maybe none of the above. Give the engine a time handicap and then we get a real game of Chess. I agree. The best handicap is to cut the computer’s time in 1/2 or maybe 1/4. I disagree. I am even not sure if this is a handicap for the computer because the human can think less on the computer time. r...

Re: so what is a fair GM handicap vs Rybka?

if you are 1800, rook odds is about an even match at 5 minutes per game. if you are 2000, knight or bishop sounds about right.

Re: so what is a fair GM handicap vs Rybka?

My opinion is that it is even impossible to do it without a knight and when you talk about a queen I am simply sure about it. You have seen all these predictions, or claims of the past to turn out wrong, sooner or later. It isn't logical to make another claim of the same type. I didn't claim that i...

Re: so what is a fair GM handicap vs Rybka?

it will never be possible for engines to give GMs queen-odds. Never say never. :roll: It sounds like opinions from the past, like "Chess computers will never reach club player level."
