    Things look bleak for white, should he resign?

    White to move:



    This problem comes from Mihai Suba, Dynamic Chess Strategy, and Fritz 8 misses white's best move.

    Ng7+ looks very promising.

    Hiarcs 9 likes that after 10 hours of analysis. I believe it loses.

    Just had a very quick glance at work and starting looking at variations after Ng3+. Looks interesting, at least.

    I was looking at that to see if it bogs black down enough, but haven't concluded anything

    Nf3 looks ok. If h3 then Ng3+ Kg4 Ne2 and the promoting squares are both covered and should be able to be protected enough to allow white to promote his pawn.
  7. 20 Mar '06 19:04
    1.Ng7+ Kg5
    2.Nf3+ Kf4
    3.N:h4 g1D
    Maybe Draw, but small possibility!
    I think white lose anything, if opponent is good player!

    Looks good to me, what's the official answer?

    I was able to draw Fritz 8 from this position. I did not move a knight first. When Fritz had white, I was able to win. Fritz moved a knight first.

    1.) Nxh4 Kxh4
    2.) Nf3+ (can fork and prevent the promotion if the pawn promotes. any If the Black king does not capture the knight, then the same fork can be had with Nf3 again and prevent the promotion of the pawn.
    At this point, the White King can clear away the c-pawn, and prepare his own promotion strategy. Black's h-pawn is nothing to worry about, because white will promote before he ever gets there.

    Then, King can work a way to the pawn, and capture it. And, then work on the other pawn that prevents his own promotional pawn. Not too difficult. Sac a knight.

    Well, then
    1....Ke4 2.g1=Q 3.Ng7ch Kg5 4.Nf3ch wins the queen.
    If 1..Ke4 2.h3 Kf4!(threatens mate) 3.g1=Q Ng3ch, 4.Qxg3 Kxg3

    White plays 1.Kc6! After 1...g1Q 2.Nxh4 Qa1 (or any queen move; 2...Kxh4 3.Nf3+ and if there is any advantage it belongs to white) 3.Nhf3, we reach the following position:



    The black king is caged and the white pawn is protected. Black can chase the white king all over the board, but cannot deliver checkmate.

    How Long did you Leave it for?? and/or How powerful is your PC??

    I should imagine that Frtiz would have found the winning move simply by brute force evaluation....given a big Hash and time
