Double-null in pawn endings only sounds reasonable to me. Did you ever test that?

Re: The near future of computer chess

I'm not "bashing" Ivanhoe. I'm simply saying that it is a reasonable position for a testing organization to refuse to test a program whose author they cannot identify. In the case of Ippolit, the use of pseudonymns made it obvious, but even if they use real names that is only useful if someone can c...

Re: Null move alterative in endgames

[quote="Uri BlassI wonder if somebody tried to replace null move pruning by random move multicat pruning(it can be used not only in endgame). The idea is simply to make a random move and search after the random move with reduced depth if the random move cause a cutoff then do the same with another r...

Re: Null move alterative in endgames

[quote="bobDo you guys do the same with null-move as I do? IE only shut 'em off when all pieces are gone? I have not (yet) tested to see what might happen with turning null-move off a bit earlier and then relying on this a little heavier. Certainly with just king and pawns, there is little opportuni...

Sorry, but I cannot imagine what you are talking about. Did I meet you in England once? If so I don't remember.
