    This comes from a book Amusements in Mathematics, by H E Dudeney (No 355)

    Strolling into one of the rooms of a London club, I notice a position left by two players who had gone. It is evident that White has checkmated Black. But how did he do it??

    The board looks like this:

    White has a Bishop on b1, pawns on a2, f6, g5, h4. King on g8
    Black has a pawn on h5 and his King on g6.

    Both answers are wrong. Either way, black would have been in check.
    But to be honest, I don't see the correct answer

    good point piderman... the bishop couldnt have moved to its location to put black in check, so it must have been a revealed check

    I think Mephisto was right.

    The board would have been set up as such

    6K1/5p2/6k1/4P1Pp/7P/8/P7/1B6

    Black then would advance his f pawn 2 spaces to f5 to block check.
    Then White would take the f pawn (en passent) exf6 resulting in checkmate

    Problem is, there is no piece that could have moved from the b1/h7 diagonal, except from the f6 pawn. But, stood the pawn on f5 it would already have been checkmate.

    Anyway, I think the two people in the club had set up this position to discuss this very same problem

    No, this is correct. Set up the board:

    6K1/5p2/6k1/6Pp/4P2P/8/P7/1B6

    Then:
    1. e5+ f5 2. exf6++

    Oh yeah, thanks piderman, I confused myself by forgetting to mentiion the discovered check caused by advancement of whites pawn

    Very intriguing puzzle! The thing I wonder about is .... Where was Blacks King before moving to g6?. It could NOT have been on the f5 square... example e4+ Kf5-g6 because of the B@b1.

    The best I can come up with is that the white g-pawn was at g4 and that would allow the Black King to occupy h6. If so then the e.p. solution works.... 1.g4-g5+ Kh6-g6 2.e4-e5+ f7-f5 3.e5-f6 e.p.++.

    Would the person with the solution post the answer please?
