an endgame and an old PC

For some amusement with chess software give this position to your 'engine', White to move it will most likely say something like = +.01. Then make whatever moves it claims are best. In just a few moves the evaluation jumps to +7.22 or +11.55 or  - you get the idea. An old version of Rybka starts out at = 0.00 but not for long!! If anyone has a really fast new engine and a couple minutes to spare I am curious what the evaluation is with better equipment

    The latest Stockfish


    0.00 =26 ply deep

    0.00 = 30 ply deep

    every ply was taking too long for it to analyse but the current computer chess champion; Stockfish is stumped by it

    Whatever engine is inside my Chessbase software (CB12)  wasn't of much help. After running it for 24 hours it was still showing 0.00. I guess the good thing is that the software won't have to worry about facing this position too often ... Smile.

    I guess I should use the "Cloud" function then I can tap into the other computers on Playchess. My program and PC combo is clearly overmatched. I am not sure, however, if the program keeps running once the PC goes in sleep mode. Maybe it didn't run the whole time. Maybe someone more knowledgeable knows ..

    It's not only that endgame the evaluation is so strange. Many endgames position even newest engines evaluates like this Laughing

    At depth 33 on StockfishDD it sees white winning with a lot of moves, takes a couple of minutes.

    Funny thing Kf2 loses for white, it looks so tempting but it just loses Undecided

    Still kinda curious as to the original position that's in the image we can't see!

  • 3 years ago


    I can't see the image either.But I have had similar responses from analysing my own games. a lot of times I notice that the computer will not even have the move that I made in the top 5 moves to be made. This happens even at 21 depth. After I make the move though I can back the move up and the engine spots it. This happens a lot while use the infinite analysis feature.

     I hope you get the image issue fixed. I wouldn't mind testing my computers speed

    Yeah, cheap-chip morons, their strategic understanding is still like a pre-K kid's.

    Look at this change of scenery, from 0.00 to +/- 1.44 after just three amazing moves by the Marauding Viking (Larsen-Donner, Beverwijk 1965)

    All this is just another great example of how the high-tech morons (that's how I call chess engines) lag far behind humans in strategic understanding of a position; they are tactical monsters, but when it comes to strategy and grasping the positional core in apparently quiet positions, they are still markedly inferior to how humans think and approach problem solving – it is not all about calculation and logic. It's about the intangibles, baby! strategic insight, intuitive thinking, imagination, creative approach, all of which is still, thank God, out of grasp for the cheap chips…
