PAWN ENDINGS. There are a great number of these, many being complicated by the addition of Pawns to other pieces. The following example, which is a position that often occurs, should be understood by the beginner:—
Put the black King on K B square; the white King on K B 6, and a white Pawn on K 6. If it is Black’s move, White can win easily; but if it is White’s move it is impossible to win, because whether he checks or not the black King gets in front of the Pawn and either wins it or secures a stale-mate.
Put the Pawn behind the King, on K B 5, and White wins, no matter which moves first, for if Black moves he allows the white King to advance to the seventh file, which will queen the Pawn. If White moves first, and the black King keeps opposite him, the Pawn advances. If Black goes in the other direction, the white King goes to the seventh file and wins by queening the Pawn.
