    My favorite mate with stipulations was her reply, "Well ok, but you have to take me to dinner first." 😲

    Seems like the solution. Though I'm still trying to figure out how to counter 16 ... f4 instead of fxe4.

    EDIT: After 17. f3 your white bishop is trapped. So I guess it is not good enough 😉.

    Perhaps this is a more forcing way.
    After 12. Bxe5 there are 3 options for white.
    a)12. ... Kxa3 (see pgn 2)
    b)12. ... fxe5 (see pgn 1)
    c)12. ... f4 13. Bxf4 Kxa3 following the principle of option a again (no problems because the bishop covers the a7-g1 diagonal at all times)

    Thanks Paladin for keeping them right whilst I was away.

    The first one was quite easy. Only the 2nd White move needs thinking about.
    All of Black's moves are forced.

    1. Bh6 Ka2 2. Bc1 Ka1 3. Bd2 {the point is that you can never go to b2 with check... once you notice that this is a cake ...[text shortened]... t of that box just to try and put it back in... 😕
    I don't understand why everybody wanted to let the king out of that box just to try and put it back in... 😕

    aha... I didn't apply that to the pawn. fxe4 puts a whole new twist on the problem then. hmmm.
