    Featuring again our new Hero RookMan..
    This week he faces BishopGirl.

    A super study by Karl (Leonid) Kubbel.

    A look at Loose Pieces and a trip into the Hall of Horror where White
    plays two of the most natural looking moves on the board and is checkmated.

    All the games come from 2015

    Greenpawn, I have a question regarding Karl Kubbel's puzzle. On black's second move, why doesn't black continue pushing the A pawn? Bxd4 covers the A square, but C3 should stop that, right?

    White simply won't play c3 - he'll just leave the bishop attacking the queening square and then win with his two protected passed pawns at his leisure.
    e.g.

    Yeah once the Bishop covers a1 the win is straightforward.
    However there is one silly line..........



    tejus - Number 6 RHP 2015 Game 11119320


    White played 60.Kc5. Stalemate.

    I thought of another possible but implausible line after I posted. Something like this:

    Somehow I got my colors mixed. Was thinking those white pawns were blacks, for some reason. Some sort of color dyslexia?

    Hi Vivify,

    It's OK.. What is worrying is how me and DataFly are quite adept
    at finding ways to screw this study up. It's a knack we have.

    Why doesn't black simply play Kd5 after capturing the knight?

    That's the whole point of the study and what transforms it from a tricky problem where you've got to try and calculate how to stop what looks like an unstoppable pawn into a work of genius:


    Black gets his queen but is checkmated in the middle of the board! No-one saw that coming!
