Position after 50. axb5: [D]8/3k4/p7/1P6/3B4/1nP5/6KP/8 b - - 0 50 Chessmaster 9000 default personality played here 50...Nxd4? and lost after 51.bxa6! I thought it's related to egtb probing but Fritz 5.32 has no problem here. Of course, after the natural 50...axb5 white has an extra pawn but black can fight for a draw with good chances, eg: 51. Be3 (51. Kf3 b4 52. Ke3 bxc3 53. Bxc3 Ke6 54. Kf4 Nc1 55. Kg5 Ne2 56. Bb2 Ng1 57. Kg4) (51. Bf2 Nd2 52. Be1 Nb3) 51... Ke6 52. Kf3 Kf5 53. h4 Na5 54. h5 Nc6 55. Ke2 ( 55. h6 Kg6 56.
