White to move. How should white proceed?
Source: ChessToday.net
Qh4
Yeah, see this pattern a lot- white would love to play Qg6 and threaten mate in three different ways (forcing black to give up the queen for the knight), so the very first move to catch my eye is Rxe6:
1. Re6 fe6 (alternative no better)
2. Qg6
And white is threatening Qh7#, Qh6#, and Qg8 mate if black guards h7 with a move like Qd7. There is no defense but to take the knight:
2. …..Qf6
3. Qf6, and white will win the bishop at f2, as well.
Black can’t do much better than fxe6 since white is also threatening Re8. I don’t see any way to avoid losing the queen for a rook at minimum.

1. Rxe6!!
{ 1. … Rg5 2. Qe4! ( threatening mate on h7 )
(2… Rg7 3. Re8+ Qxe8 4. Qxe8+ Rg8 5. Qxg8#)
(2… Qxf6 3. Rxf6 +-)
( 2… Qd5 3. Re8+! Kg7 4. Nxd5 +-)
(2… Rg6 3. Re8+ Qxe8 4. Qxe8+ Kg7 5. Nh5+! Kh7
6. Qxf7+ Kh8 7. Qxg6 Bd4 8. Qe8+ Kh7 9. Qe4+ Kg8
10. Qxd4 +-) }
{ 1. … fxe6 2. Qg6!
(2… Qxf6 3. Qxf6+ Kh7 4. Qxf2 +-)
(2… Rd7 3. Qxh6+ Rh7 4. Qxh7#)
(2… Qe7 3. Qg8#) }
{ 1. … h5 2. Qe4!
{2… Qg8 3. Re8! Rd8 ( 3… Qxe8 4. Qh7#) 4. Qh7#}
( 2… Kg7 3. Qh7+ Kf8 4. Qg8#)
( 2… Qxf6 3. Rxf6 Rd2 4. Qe8+ Kh7 5. Qxf7+ Kh8 6. Rh6#) }

1. Nxd5 isn’t good enough after 1. .. Bxe1 (1. .. Qxd5+? 2. Kxf2) 2. Qd4+ f6! 3. Qxf6+ Qxf6 4. Nxf6
The winning move is 1. Rxe6
If 1. .. fxe6 2. Qg6
If 1. .. Rg5 or Bxg3 or h5 or Bc5 then 2. Qe4
If 1. .. Rd2 2. Re8+ Qxe8 3. Nxe8 Bd4+ 4. Kh3
If 1. .. Bd4 2. Re8+ Qxe8 3. Nxe8 Rd8 4. Qe2
White’s N looks dangerous for h7 + g8 but is attacked by black’s Q and also Bf2 attacking Re1.
1.Rxe6 overcomes both.
if 1…fxe6 2.Qg6 hitting h7,g8,h6.
if 1…h5 2.Qe4
if 1…Rd4 2.Qf5
if 1…Qf8 2.Re8 Qxe8 3.Nxe8
0-0-0
-0-0-
1.Rxe6 fxe6
2.Qg6 wins
if
2….Re7
3.Qxh6 Rh7
4.Qxh7#
if
2….Be3
3.Qh7#
if
2….Qxf6
3.Qxf6+ Kh7
4.Kxf2
wins less quickly
Rxe6 as after fxe Qg6 threatens mate on g7 and via h6.
RxE6 FxE6
Q-G6 threatening both QH7# and QxH6#.
RxE6 FxE6
Q-G6 threatening both QH7# and QxH6#.
1. R:e6 fe 2. Qg6 leads to unstoppable mate threats on g8, h7, and h6. So Black must acquiesce to 1….Bd4 2. Re8+ or the like.
