You answered to Eduard Nemeths sentence. >(BTW -319.61 is mate in 20 from rybka, sigh...) > >Guenther I actually think I know what Chandler is trying to say, but he's being so vague and coy about it (as usual) that it is impossible to understand him. What I THINK he is complaining about with the above output from Rybka, as well as the output from AnMon (in comparison to what he praised in The King's output) is that the PV does not list all of the moves to mate. Rybka only shows up to White's 8th move, and AnMon only showed to about move 17. What Chandler doesn't realize is that many programs do not display their entire PVs, even though they have calculated all the way out to mate. The King can even exhibit this behavior of giving a mate score that results in a longer move list than can be displayed. This doesn't mean that the evaluation is wrong, but rather simply that the author has decided to artificially limit the PV output. And now I'm done defending Chandler. He's on his own from here.... :-) jm
