    Yeah, yeah, this has been posted before. But what if
    1.Bxc6 d1=B
    or 1.Bxc6 d1=N
    ?

    Read my posts on the previous page...

    I said the following:

    If black responds with d1B
    1. Bxc6 d1B
    2. gxf8R Kd6 (black's only legal move)
    3. Qd2+ Kxc7
    4. Qd8#
    There are others move for both black and white instead of 3. Kxc7 4.Qd8#
    But all are checkmate in one move.

    If black responds with d1N
    1. Bxc6 d1N
    2. gxf8Q Nxb2+ (other moves available for black but making little difference)
    3. Qxb2 c1Q (piece promotion is black's only legal move)
    4. c8Q#

    You are correct - my apologies. That concludes the problem. I owe you the source: Peter Hofman, dedicated to Tim Krabbé, published in Schach, september 2005.
