But I really think, in this sort of endgame, one should not easily trust engines. Some arguments. Assume KQPKQ and an engine without TBs. Also, ignore for the argument the 50 moves rule. There are positions in KQPKQ, which need more than 50 moves, until a pawn will advance. Earlier in this (or in a related) thread, you argued with tactics. When 50 moves are needed (or when 30 moves are needed) until a pawn advances, tactics will be out of reach for (almost?) any chess engine. You critizised Tiger for the high eval. I did not look close enough, neither do I have the knowledge. But in general it seems possible to me, that with rather sophisticated knowledge in the engine, such a score is reasonable. I don't know, if Tiger has such sort of knowledge, or if such knowledge is even applicable here. Perhaps, Tiger was lucky, and in other situations, the same algoritms, that show +5 here will hurt. Also, as far as I read the threads, it seems not totally clear yet, if black will win. But arguing with tactics is not valid here, IMHO. Regards, Dieter
