It can be hard to stop two passed pawns with a Bishop, as one passed pawn can be sacrificed to allow the other one to escape from the Bishop.
The solution to last Monday’s problem is that White draws with 1. g3+! Ke4 2. Bc2! Qg4+ 3.Kf2! Kf5 4. Rd4+ e4 5. Rxe4 Qxe4 6. g4+! hxg4 7. Kg3 Qxc2 and it is stalemate.
