Puzzle from my latest daily game

Black to move mate in 4


That's lovely.

I know that's how it panned out in your actual game,, but it strikes me that the two rooks connected on the b-file would work just as well.

Just a thought. Well done!
Forget that. Rook wouldn't work, since White can capture your bishop with his bishop on f6.

If White tried that with your queen on b6, it would have been mate in 2:

1. ... Bb2+. 2. Bxb2 Qxb2#
Actually, with the rook and queen's positions swapped, I'm struggling to find a way for Black not to lose.

What was I thinking?!!
No. Seems Black is still in the stronger position. Anyway, great puzzle and well played. Peace, out.
