White to Move and Mate in 4, as before No Computers and please don't ruin the problem for others by posting the solution. Just PM if you need the answer or wait and I will post the answer later in the day.

Clue: Once you find the key move the rest should be easy. Wink2

I promise you, it's a forced mate in four! Profile

Finding Whites 1st move was hard for me. It's just not the type of move I would normally play. (Clue! Clue!)

?? g6? How is that forced? After g4 Bxd7 screws that whole answer up.

Because if g4 Bxd7 then White has Qh5 CheckMate. (Which is Mate in 2 Moves) If instead g4 Kxg5, Qh5+ Kf6, then Rf7 CheckMate. (Which is Mate in 3 Moves) Profile

Black can only hold out the longest with the given solution, it's the best defense that Black has to offer:

1. g4! g6
2. h4 Rh8
3. Qh7 Rxh7
4. Rxh7 #

Yes!! You are correct, and it's a pretty good series (Power Play) by Daniel King. I have volumes 1-3 so far and plan to buy the rest of the series. bow bow bow
