    White (Caps)	

1)PxBP e.p. threatening P-B7 mate. Blacks last move was P(B2)-B4.
 
2)Its not possible for blacks last move to be P(Q2)-Q4 because blacks
  queens bishop was needed to be sacked in order to arrive at the pawn
  formation given. If the pawn was still on Q2, the bishop would never
  have been able to move. Whites pawns must make ten captures. Black
  has lost only 3 pawns and 7 pieces. The bishop was needed.
