Bf7 $1 Ng7 {perhaps the best try but Black is tied in knots as neither the N on g7 nor his king can move, e.g.} (1... axb5 2. Bxe8 {costs Black his knight to stop the d-pawn queening}) (1... Kg7 2. Bxe8 Kf8 (2... Nxe8 3. d7) 3. d7 Ke7 4. Nc3 {leaves White with an extra piece}) 2. Nc7 a5 (2... Nd7 3. a5 f4 (3... e4 4. Bd5) 4. Bd5 {the b7 pawn falls and it is all over}) 3. Nd5 Nd7 (3... Nxd5 4.
