    I reached this position as white while playing against chessmaster and settled for a draw. Is there a win for white here? Thanks in advance.
    White to play.

    To be perfectly honest, I think you might be lucky to draw this one let alone win it. I'll post an analysis later if I get the time.

    I'm pretty sure there's a win for black.

    Here's some possibilities:

    1.b4 a4 and white has to deal with the outside passed pawn. Black will be able to grab the g-pawn and then come back to support his protected passer. c4 won't work because after bxc4 both pawns are immune from capture by the white king. For instance: 1.b4 a4 2.Kc2 Ke6 3. 3.Kb2 Kf6 4.c4 bxc4 5.b5 Kxg6 6.Kc3? a3 black can stop the b-pawn easily.

    1.c4 bxc4 2.Kc3 Kc5 3.bxc4 a4 and black is winning by escorting the a-pawn. For instance: 1.c4 bxc4 2.Kc3 Kc5 3.bxc4 a4 4.Kd3 Kb4 5.c5 Kxc5 6.Kc3 Ng7 7.Kb2 Kb4 8.Ka2 a3 9.Ka1 Kb3 10.Kb1 Nf5 11.Ka1 Nd4 12.g7 Nc2+ 13.Kb1 a2+ and white is getting mated.

    That leaves king moves:

    1.Kd3 Ke5 and 2.c4 doesn't work now because of 2...b4 for instance: 2...b4 3.Kc2 Ne7 4.g7 Kf6 5.Kd3 Kxg7 and black will win.

    1.Kd3 Ke5 2.b4 is losing like above.

    1.Kd3 Ke5 2.Kc2 Kf6 and black is winning the pawn and the ending.

    1.Kc2 Ke5 2.c4 b4 3.Kd3 Ke6! (Kf6 is drawing now to c5) 4.Ke4 Kf6 now after c5 white can't jump immediately to c4 and b5 snatching black's pawns. For instance:
    4...Kf6 5.c5 Kxg6 6.Kd3 Kf7 7.Kc4 Ke6 8.Kb5 Kd5 9.c6 Nd4+ 10.Kxa5 Nxc6+ and black is winning.

    1.Kc2 Ke5 2.Kd3 Ke6! (like before, stopping Kc4-b5 after c4) 3.Ke4 a4! winning
    2...Ke6 3.c4 b4 transposing to a previous line I think
    2...Ke6 3.Kc2 Ke7(losing time, going to f6 too soon will allow c4 drawing) 4.Kd3 Nd6
    5.c4 bxc4+ 6.bxc4 Nb7 7.Kd4 a4 8.Kc3 Nc5 0-1
    5.Kd4 Kf6 6.Kd5 loses to a4
    6.Kd3 Kxg7
    6.c4 b4 7.Kd3 Kxg6 8.Kxd6 a4 0-1
    7.c5 Nb5+ 8.Kc4 Na7 9.anymove Kxg6(or g7)

    I think y'all see the ideas by now. If the white king advances to far then black can create a passer and queen. And if the white king just goes back and forth black will munch the g-pawn.

    A silly question - You played this against Chessmaster. Can't you use Chessmaster to analyze the position?

    Edit - btw, I think the other posters are right. My engine is finding nothing but losing lines for White.

    White can't possibly win with the knight blocking the g pawn. If white's king tries to go to the kingside, black plays a4 and runs the a-pawn. If you got a draw as white, you did well.

    Hi Mate,

    No White win as the Knight on g7 can hold the g-pawn and
    if the White King tries to dislodge it then the Black a-pawn will win.

    As SF says all winning chances with Black.

    Looked at a few of your games.

    Something to be learned from game Game 4565169 .

    Put position after Black's 56th move 56...Ke6 into Chess Master.
    You take Black, see how easy win is for White.

    White to play.



    Or better still you take White again and win it.

    OK, I guess I've just answered my own question.

    Besides the fact that arterios might have just preferred actual human analysis (Are ya happy, greenpawn? I know that's what you were thinking, you were just too nice to say anything ) , I just tried analyzing the position with Chessmaster, and it wasn't fun.

    It's cumbersome to set up the position and start the analysis, and the analysis features are limited. Plus, it was a lot slower getting to any reasonable ply depth compared to my other engines in Arena. In short, CM sucks at analysis. I'll stick with Arena.

    Hi Mad One.

    No I was not thinking anything like that all.

    I was wondering why one would agree a draw with a computer?

    You play on and if you are getting beat you swap sides.

    I play Grommit, it's sly, when it evaluates the position as won
    say a +4 I swap sides and find out it was lying.

    Swapping sides, good idea. As long as Grommit doesn't start saying, "I'm sorry, Geoff, I can't let you do that."

    Hey thanks for taking the effort. I knew i had screwed that one some how.
    I guess the simple 57.Rd4 wins..
