With wKc2 and wBc3: bPf4 can be saved!

This comes for the price of a pinned white bishop.
I am not convinced that this is necessarily better.

a technical point :
you can think about a mate on a8 with black reaching g5 in 2 moves :

  • knight b7->b5 would control a7
  • rook a2->b5 would disappear after 1…f7xe8
  • rook e8->b5 (with 1…fxg8) is not possible due to the bishop c5
  • bishop g8->b5 is forbidden by the pawn f7
  • f2->b5 would give check to the white king
