Re: At a glance you may think this is a draw. White wins!

tried your position, for some reason did not get your results. did you do no 50 rules move ? Yes, I did used "No 50 moves rule (Depth To Promotion)". Now I managed to get more precise results using two seeded positions: [D]8/8/8/PkP5/1P4p1/5pKp/8/8 b - - 0 1 WHITE WINS [D]8/8/PkP5/1P4p1/5pKp/8/8/8 ...

Re: At a glance you may think this is a draw. White wins!

is this the critical position you put in? [D]2Q5/8/8/P7/1P4p1/3k4/7K/5n2 w duncan No, I set this position: [D]8/8/8/PkP5/1P4p1/5pKp/8/8 b - - 0 1 But of course one should get the same result by setting that Q/N position to WHITE WINS. tried your position, for some reason did not get your results. d...

Re: At a glance you may think this is a draw. White wins!

If one sets the critical position's value to DRAW, FinalGen reports a win for 1.Ke2 and 1.Ke1. Sorry, I made a mistake in my previous post. You should read: If one sets the critical position's value to WHITE WINS, FinalGen reports a win for 1.Ke2 and 1.Ke1. is this the critical position you put in?...

Re: At a glance you may think this is a draw. White wins!

A beautiful position that illustrates the advantage that a single tempo can give. Then zugzwang and black is lost. The key to this position is looking at it yourself , before using an engine. It's very instructive! Some very strong engine(s) also struggle here. Komodo CCT after 5 min cannot see the...

Re: At a glance you may think this is a draw. White wins!

Critter needed about 8 minutes to find the winning move. I let the analysis run overnight: [D]4k3/5ppp/8/8/8/8/PPP5/3K4 w - - 0 1 Critter 1.6a x64, 4-Gb hash: 32/61 06:12 2 957 072 190 7 947 965 0,00 a4 h5 a5 Kd7 a6 Kc7 b4 h4 Ke1 Kb6 b5 g5 Kf2 g4 Kg2 g3 Kf3 Ka7 Kg2 Kb6 32/61+ 07:38 3 656 933 988 7 ...

Re: Human killer engine - a cafè-monster

Has anyone made a "Human killer engine"? I mean an engine that not always plays the best move because it will: 1) Have open and complicated positions 2) go for positions where it can perform a surprising combination 3) set a trap for the opponent. 4) more things like that . I remember playing an en...

Re: How to lose Once and again AND STILL KEEP YOUR SELF SANE

Fernando - a tip would be to check out Lucas Chess (you'll find it via search - it's shareware). I did just that some days ago and this program was a very pleasant surprise! It's possible to play against 32 personalities of different strength and get elo. The weakest players are real bad so this pr...

Re: expert understanding of computer chess

That is a good question. A score of zero would imply he is right the same number of times he is wrong and I think a GM would score negative. That is not necessary bad - a random guess would be very negative so I'm saying he would do better than random but not that much better. There are probably be...

Re: Expert understanding of computer chess.

Sorry if I did not explain myself enough clear: I understood that you propose self play, but I say that for example a GM sees a game of a top engine and if he/she can understand the typical depths for the strength of the moves played in that game, it will be a lottery to say 'depth X' blindly witho...
