My chess defensive don’t always produce a win BUT:
The white king does not have great defensive position. I would use my pawns to block the bishop and attempt to get an open line to the white king with my rooks.
(of course in my tournament play I can never see the queen/bishop checkmate coming and I have no defense for it 😀)
the chess engine apparently disagree with my play below but this would be an accurate example of my current chess play.
