Joined 17 Oct '03 Moves 64193 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 😉.

Joined 17 Oct '03 Moves 64193 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)

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

Wilfried, you moved the White king... I think it starts with this sequence, after which the white bishop can be brought in the game to mate.
