White to move.

Always consider attacking opportunities where the power of double-check can be used.

Very nice. Tough to spot if you hadn't said it was a double check problem.

When capturing, it helps to remove the pieces from the board...

1.Qxh7+,Kxh7 2.Ne4xf6++,Kh8 3.Ng6#

Anyway Rag is right,if you didn't talk about double checks it would have been much harder to spot.

1. Nxg6 is an impossible move.

Bowmann, if these are lessons opposed to just plain aul tactics problems, shouldn't you explain what to look out for, signs that the double check might be on, etc?

If you meant Nxf6, then that's met with gxf6 and the h7 square is covered by the queen.

I don't believe so. They're about pattern recognition. In this example, we have two things: recognizing the opportunity for checkmate, coupled with the double-checking motif.

However, if lower-rated players wish to ask questions here, or even PM me, I shall try to help further.

1. Qxh7+ Kxh7
2. Nxf6+ (the double-check) Kh8
3. Ng6 mate.


Double-checks are powerful because two of the three options for your opponent to escape from check are automatically removed...
