Default Sharpen Your Tactics, problem 77. (Analyze)

Dear Group,

This one stumps me too.

Black: [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected] a6, b7, f7, g7, and h7.

White: [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], c2, c3, e4, f5 and h2.

White to move.

Why isn't my solution just as valid?

My solution: Qh5, Qxh5, Rxg7+, Kh8, Rg1++.

Book: Qh3! Qh3, Rg7,Kh8,Rf7,Kg8,Rg7 Kh8, Rg8++

Tushar

Ps. Thanks.

Something's wrong with the position. I suspect Black Kg8 instead of
Kg7 and Pg7 instead of Pg6 and White Bb3 instead of Bc3.

1. Qh3 is better than 1. Qh5 because Black can draw out the matter
with 1. Qf6.

1. Qh3 Qf6 2. Qg3 g6 3. Bxf6 Nxf6 4. gxf6 and Black is dead.
Where 1. Qh5 Qf6 2. Bxf6 Nxf6 3. Qh6 Ne8 4. f6 g6 5. Rxg6+ hxg6 6.
Qxg6+ Kh8 7. Bxf7 Rxf7 8. Qxf7 just gives a won endgame.

If Black takes the bait it makes no difference but 1. Qh5 Qxh5 2.
Rxg7+ Kh8 3. Rg1+?? f6 and Black escapes and wins. Removing the f7
pawn to give the double check is essential. 3. Rxf7+ Kg8 4. Rg7+ Kh8
5. Rg1+?? Nf6. Therefore the double check when Black can't put
something in the way. 5. Rg8 mate.
