Arabian Mate Puzzle One: White to move, mate in 2.


The Arabian mate is one of the oldest studies of a checkmating pattern in chess. Records show that theory and lessons involving this interaction between the Knight and Rook date back to the 1400s.

Note these interactions shown immediately below. The enemy King must be backed into a corner. The Knight must be on the long diagonal two squares away from the King. The square between the King and Knight may be empty, or contain a piece, so long as it cannot freely capture the Knight. Finally, a heavy piece (the Queen or, most commonly and illustrated here, a Rook) is brought onto one of the squares adjacent to the King which the Knight controls - both protecting the heavy piece, and preventing escape.

Basic premise of Arabian Mate

Below is a mid-game position which will end in an Arabian Mate. The board looks quite different from the example above, doesn't it?! Before reading past the board, try to guess what Black will try to do to save its Queen.
