Pawn can
1) move one cell forward (if that cell is empty)
or
2) attack cell which is one step diagonally forward, and occupied by opponent's pawn (which is beaten and removed after attack; player's pawn is moved to the cell of beaten one)

In that problem if player can attack with one of his pawns he must attack in that turn.

A pawn can move one field along the vertical and beat one field along the diagonal. Black pawns move from i'th row to (i-1)'th only. White pawns move from i'th row to (i+1)'th only. The row number 1 is the bottom and the row number 3 is the top.
