White to move. How should white proceed?
Source: ChessToday.net
Given the threat of Qh1, white must act with forcing moves, I think. This suggests Re8+ as a possible move, even if you can’t see immediately that this wins (which I can’t without working through it):
1. Re8 Ke8
2. Qg8 Bf8
If Kd7, white takes at g7 with check and will mate in another 1 or 2 moves since the black king can’t get through c6 or d6. Continuing:
3. Nc7 Kd7 (Kd8 4.Qf8 Kd7 5.Qe7)
4. Qf7
Important to keep checking here. Continuing:
4. …..Kd6
5. Rd1 Kc5 (Ke5 6.Rd5#)
6. Qd5 Kb6 (Kb4 7.Qb5#)
7. Qb7 Ka5/c5
8. Qb5#
1 Re8+ ..
2 Qg8+ ..
3 Qf7+ ..
4 Qe8#
1. Re7! Bg6
2. Nc7 and I feel white is doing good. I can’t see any good defence for black.
Re8 followed by qg8 appears to win across all variations
Re8+ Ke8
Qg+ and mate soon
1. Re8+, Kxe8
2. Qg8+, Kd7
3. Qf7, Kd8
4. Qe7+, Kc8
5. Qc7#
1. Re8+ Kxe8 2. Qg8+ does the trick, although there are a lot of sub-variations.
2. .. Bf8 (2. .. Kd7 3. Qf7+ Kd8 4. Qe7+ Kc8 5. Qc7#)
.3. Nc7+ Kd7 (3. .. Kd8 4. Qxf8+ Kd7 5. Qe7+ Kc8 6. Qe8#)
4. Qf7+ Kxd6
(4. .. Kc8 5. Qe8#) (4. .. Be7 5. Qxe7+ Kc8 6. Qe8#)
5. Rd1+ Kc5
(5. .. Ke5 6.Rd5#)
(5. .. Bd3+ 6. Rxd3+ Kc5 (6. .. Ke5 7. Rd5#) 7. Qd5+ Kb6
(7. .. Kb4 8. Qb5#) 8. Qxb7+ Ka5 9. Qb5#)
6. Qd5+ Kb6 (6. .. Kb4 7. Qb5#) 7. Qb5+ Kxc7 8. Qxb7#
there is definitely a way to checkmate. i think we should start with
1. Re8+ Kxe8
2. Qg8+ Kd7
3. Qf7+ Kd8 (Kc8, 4. Qc7#)
4. Qe7+ Kc8
5. Qc7#
if
2. … Bf8, then
3. Nc7+ Kd8
4. Qxf8+ Kd7
5. Qe7+ Kc8
6. Qe8#
if
3. … Kd7, then
4. Qf7+ Be7
5. Qxe7+ Kc8
6. Qe8#
if
4. … Kd8 (Kc8, 5. Qe8#), then
5. Qe7+ Kc8
6. Qe8#
if
4. … Kxd6, then
5. Rd1+ Kc5 (Ke5, 6. Rd5#)
Bd3 is useless
6. Qd5+ Kb6 (Kb4, 7. Qb5#)
7. Nxa8+ Ka6
8. Be2+ Bd3
9. Bxd3+ b5
10.Qxb5#
i hope i didn’t complicate matters more than necessary. greets, jan
Re8+Ke8 Qg8Kd7 Qg7Ke6 Re1
What about Re8+?
The King can be hunted down.
1.Re8+ Kxe8
2.Qg8+ Bf8
(2…Kd7 3.Qxg7+ Kd8 4.Qe7+ Kc8 5.Qc7#)
3.Nc7+ Kd7
(3…Kd8 4.Qxf8+ Kd7 5.Qe7+ Kc8 6.Qe8#)
4.Qf7+ Kxd6
5.Rd1+ Bd3+
(5…Ke5 6.Rd5#)
(5…Kc5 6.Qd5+ Kb6 7.Nxa8+ Ka6 8.Qxb7+ Ka5 9.Rd5+ Ka4 10.Qb5#)
6.Rxd3+ Kc5
7.Qd5+ Kb6
(7…Kb4 8.Rd4#)
8.Nxa8+ Ka6
9.Qxb7+ Ka5
10.Rd5+ Bc5
11.Rxc5+ Ka4
12.Qb5#
1. Re8+… 2. Qg8…

wNb5 to C7 for taking the Rook.
Te8+!
I ‘got’ this this morning but because from a game then I looked around and found it here:
http://kevinspraggett.blogspot.co.uk/2012/08/sants-tournament-rd-3.html
(Scroll down to play through game.)
The puzzle is white to play 26th move but it’s white’s 24th that is
most brilliant!
0-0-0
-0-0-
I might actually like:
1. Bxb7 Qh1+
2. Ke2 Re6+
3. Kd2/Kd1 Rxe1
4. Rxe1
with Bxa8 to follow.
Or
1. … Re6
2. Rxe6 Qh1+
3. Ke2 Qxa1
4. Re7 Bg7
5. Bxa8
also looks nice.
Couldn’t figure out what is wrong with this…
1. Re8+! Kxe8
2. d7+
Black must take d7 (either with bishop or with king). For example, if 2…Kd8, then 3. Qg8+ forcing black to take on d7.
If 2…Kxd7 then
3. Qf7+ Kd8
(If 3…Kc8, then 4. Qc7#)
4. Qc7+ Ke8
5. Re1+ Re6
6. Nd6+ Kf8
7. Qd8+ Re8
8. Qxe8#
If 2…Bxd7 then
3. Qg8+
If 3…Bf8 then
4. Re1+ Re6
5. Nc7+ Kd8
(If 5…Ke7 then 6.Qg5+. If 6…Kf7 then 7. Bh5+ forcing 7…Qh5 8. Qxh5+. If 6…Kd6 then 7.Nb5#.)
6. Nxe6+ Bxe6
7. Qxf8+ Kc7
8. Qe7+ Nd7
9. Rc1+ Kb6
10. Qd6+
At which point, the white Q, R and B can corner the king into a mate.
Nearly everyone got this one correct. It could play out like this:
1. Re8+!! Kxe8
2. Qg8+ Bf8
3. Nc7+ Kd7
4. Qf7+ Kxd6
5. Rd1+ Bd3+
6. Rxd3+ Kc5
7. Qxf8+ Rd6
8. Qxd6+ Kc4
9. Rd4# or Rc3#
1. Re7 also can win, but it is a longer haul to actual checkmate:
1. Re7 Rf6
2. Nc7 Nc6
3. Bxc6 bxc6
4. f3 Qh5
5. Rae1 Rxd6
6. Nxa8
Black should resign.
1. Re7 Bg6 also can win as suggested by Haridaran:
2. Nc7 Bf6
3. Rae1 Qh1+
4. Ke2 Qh4
5. Kd1 Bxe7
6. dxe7+ Qxe7
7. Rxe7 Kxe7
Black should resign.
I notice that one of my two answers from yesterday has failed somehow.
What I said in my first post was:
“I certainly guess it goes
1. Re8+ Kxe8
2. Qg8+ Bf8
but it’s too hard for me to find a mate from there.”
Impressive that so many of you found a mate from there!
I’m certainly not good at lengthy king hunts in open landscape!
(deep knights is much more fun:-)
