White wins

The a4 pawn prevents a simple win (1.Rf4 followed by 2.Ra4#). In order to win, white will try to reach the same position but without the a4 pawn. But how does the "disappearing pawn magic trick" work?

1. Bf3! Logical try: 1. Rf4? Rd6! -+; 1. f3? Rf1! = 1... Rd4 1... Bxf3 2. Rxf3

5... Rxa5 6. Rc1# 5. Kc3! 5. Bxd7? Rxd7 6. Rxh6 Rd8 = 5... Rd1 6. Kc2 Bg4 We are back to the initial position but the a4 pawn has disappeared! 6... Rd4 7. Bxd7 Rxd7 8. Rf4! +-

The a4 pawn has disappeared!

7. Rf4! Rd6 8. Ra4#
