    The OP's board is upside down. The pawn is on the a-file, moving towards the top of the board.. At least, that was my assumption. You're right, though, if the pawn were on the h-file and moving towards the bottom of the board, it would have been a trivial win for Black, and the OP would never have asked the question.

    Is this a draw? (I've tried it and I think it is)
    Yes, it's a tablebase draw. (Interestingly, regardless of whether it's from White's or Black's point of view, and regardless of whose move it is.) But what does this have to do with the OP's question?

    If board is turned from black view then its dead draw. If corner square is not the same as square of bishop then its impossible to win.

    (unless the opposing King can't reach the corner in time - there are some interesting (study) examples)

    Of course. But I did mean positions (like this one) where king is on corner.

    I misquoted indeed. I wanted to quote only the part

    "If corner square is not the same as square of bishop then its impossible to win."

    i.e. I played this in a game three years ago:



    1. Nxa6+!?

    Is this enough for a draw?

    Note: all diagrams have White's pawns moving upwards and Black's pawns moving downwards.

    I assume that would be Bh5, followed by h7

    1. Bh5 is correct, the 'seduction' of the position is
    1. Bf5? Kf7
    2. Bh7 Kf6! with 2. ... Kg5 draw, or if the Bishop moves, 2. ... Kf7 again and the King can reach the corner.

    This one looks fun. I'm guessing 1.Ke2, then 2.Kf3. Then White can either capture the a-pawn, or if Black protects the a-pawn with the bishop, then White can maneuver his king to the h1 square, securing the draw.
