Perpetual Check

If a player is able to check the opposing King continually and indicates an intention to do so the game is considered a draw. In the following position, for instance, White on the move can draw the game by giving a perpetual check on e8 and h5. Black cannot help herself as she has to go back and forth with the King on h7 and g8. Without the possibility of this perpetual check White would be lost, for he cannot prevent the Pawn a2 from queening and with two Queens against one Black would easily win as will be seen later from the discussion of elementary endings.
