White has lots of ways to win this game, but the fastest involves winning the black queen!

1.Ne6+








1...Qxe6

Forced.  Here are the alternatives:

  1. 1...Kc8 Loses immediately to 2.Qf8 mate.

  2. 1...fxe6 demonstrates the interference theme - the pawn at e6 interferes with the black queen's protection of the e7-knight, and that opens the door to doom: 2.Qf8+ Kc7









Analysis Diagram: after 2...Kc7

Here you can clearly see the interference at work: compare the diagram above with the starting position, and you'll see that the e6-pawn (that's the pawn that just captured White's knight) interferes with the black queen's protection of the knight at e7.

3.Qxe7+ Kb8 (3...Kc8 4.Rh8+ Rg8 5.Rxg8#) 4.Rh8+ Bc8 5.Rxc8+ Kxc8 6.Ba6+ Kb8 7.Qb7 mate.

2.fxe6

Black has no hope playing on a queen down, so best to resign this position, and start setting up the pieces for the next game!
