Nxh8 Rxh8 In chess, to win an exchange means to win an opponent rook for your own minor piece (bishop or knight). To win an exchange also means to win 2 extra pawns by material because 1 rook is equal to 5 pawns and a bishop or knight is equal to 3 pawns. How to win an exchange (rook for knight) in the above position?.. The White knight may deliver fork from f7, but how to get on f7? First, White moves his knight on e5 to aim at f7 and to attack the Black rook on c4. By attacking the rook on c4, White wins 1 tempo - Black may not defend the f7-square because his rook is under attack. Being not able to defend f7, the Black rook moves on c8. After this, the White knight takes the pawn on f7 with check and fork... Having conducted this chess combination, White has won an exchange (rook for knight), or 2 extra pawns in material.Back to top ^       Solution to Puzzle 90 1. Rc8+ Kxc8 2. a8=Q+ Kc7[1. Rc8+ Kb6? 2. a8=Q] The above position is a typical position to learn how to promote the pawn... Right now, the White pawn cannot be promoted because the a8-square is occupied by the friendly rook. The White rook must clear a8, but where to move the rook? And there is the only solution... First, White moves his rook on c8 to clear a8, to sacrifice the rook and give check (if White does not give check, the White pawn will be captured)... After this, the Black king has to take the white rook (see variation 1), and the pawn will be promoted. The Black king must not move on b6 (see variation 2). As result of this chess combination, White has promoted the pawn. See other chess puzzles for beginner: • Chess Puzzles for Beginner 1-90
