if he does that, white can take with the bishop. black's only real move after that is the revealed check with his pawn, but then the king moves to e1 and can capture the pawn the next turn. black can then play bishop to f3 and prevent the rook from checking him, but white is wide open to do whatever he wants at that point anyways. black could maybe stalemate? idk.   it's black's turn, you can tell because the white king is highlighted to show his last move.   actually, looking at this again, black could go pawn f7 to f6 which nullifies the white rook, then he might still have a shot.
