White to move. How should White proceed?
Exchange rooks with check and follow with Qh8, which threatens mate. After black queens white plays Kh2-Kh3, and finally g2-g3 to guard black checks.
1- Re8+, RxRe8 2- Qh8+, Kf7 (if KxQ then Rxe8#) 3-)Qxe8+, Kf6 4- Qe5+, Kf7 5-Qg7#
Right?
No need for 3.Qxe8+ Qg7 is a checkmate.
Quick and easy:
1. Re8! Re8
2. Qh8
The hard move to spot, but the real purpose behind white’s first move- clear the line to h8:
2. …..Kh8 (Kf7 3.Qg7#)
3. Re8#
1. Re8+ Rxe8
2. Qh8+! Kf7 *
3. Qg7#
* or if 2… Kxh8
3. Rxe8#
aside: what will be the result of Anand-Carlsen in the first 12 rounds? rank your choices! http://goo.gl/Szd0y
Re8+ Rxe8
Qh8+ Kf7
Qg7#
Or if the King takes on h8, Rxe8#
1. Re8+ R:e8
2. Qh8+ K:h8
3. R:e8#
If
1 … Kf7
2 Qg7#
Re8+ followed by Qh8+ wins
1. Re8+ Rxe8 2. Qh8+! Kxh8 (2. … Kf7 3. Qg7#) 3. Rxe8#
1.Re8+ Rxe8 2.Qh8+! kf7 3.Qxe8+ kf6 4.Qe5+ kf7 5.Rf1+ kg8 5.Qe8#
Re8+ Rxe8 (forced; Kf7 followed by Qg7#)
Rxe8+ Kf7
Qh8 to be foollowed by Qf8# (nothing can prevent this as far as I can see).
Good you didn’t write Mate in XX 🙂
1. Re8+! Rxe8
(If 1. … Kf7 2. Qg7+ checkmate)
2. Qh8+!! Kxh8
(If 2. … Kf7 3. Qg7+ checkmate)
3. Rxe8+ checkmate

the chess community keeps getting it right!
My previous `solution’ was wrong…the promotion of the black b pawn was missed.
So, let me know try the following:
Re8+ Rxe8 (forced)
Qh8+ Kxe8 (forced;…Kf7 followed by Qg7#)
Rxe8#
I think there is no lacuna here?!
The first temptation is to try
1.Re8+ Rxe8
2.Rxe8+ but after Kf7 and Qg7+ the BK escapes.
Then appears the ‘boxed in’ idea:
1.Re8+ Rxe8
2.Qh8+!
if 2….Kxh8 3.Rxe8#
if 2….Kf7 3.Qg7#
0-0-0
-0-0-
1. Re8+! Rxe8 (Kf7 Qg7#)
2. Qh8+! Kf7 (Kxh8 Rxe8#)
3. Qg7#
Funny.
1. Re8+
1. … Kf7
2. Qg7#
1. … Rxe8
2. Qh8+
2. … Kf7
3. Qf8#
2. … Kxh8
3. Rxe8#
1. Re8 Rxe8
2. Qh8 Kxh8
3. Rxe8#
or
1. Re8 Rxe8
2. Qh8 Kf7
3. Qg7#
1. Re8 R*e8
2. Qh8! and forced mate
