It is easy to see that the position is a draw. black can put the king at h8 and play with the king from h8 to another square and back to h8 and if there is no legal move for the king to play with the pawn. It is chessbase fault that they let their engines to resign games. computers should never resign even if the score is 10 pawns against themselves because there are fortress positions that they do not understand. In this case nimzo is not the only engine that does not see the draw. Doctor3 also evaluates the position as a clear advantage for white(+3.93) Fritz5.32 also sees a clear advantage for white Exchess2.51 also sees a clear advantage for white(+6.56 at depth 14) I think that more engines are going to resign if you add a white pawn at h4 instead of the black pawn at h7 (see fritz5.32 evaluation) It also changes from 0.00 at the start of the search to a big evaluation.
