White to move. How should White proceed?
r1bn1k1r/bpp2ppp/3p3n/p1qNp1N1/4P2Q/1BPP3P/PPK3P1/5R2 w – – 0 1
White Knight X pawn, check.
The rest is just systematic.

1. Nxh7+
if 1. … Rxh7 then Qxd8++
if 1. … Ke8 then Qe7++
Square f7 is easily spotted as the focus of the attack. In addition to that, the white queen threatens d8, which allows
1. Nxf7!! immediately. Black must protect square d8.
1. … Nc6 Nf7 cannot be taken:
1. … Nhxf7 2. Qxd8#
1. … Ndxf7 2. Qd8#
Other moves
1. … g6
2. Nxe5+ Kg7
3. Qf6+ Kg8 Ne7# or
1. … Bd7
2. Qe7+ Kg8
3. Nxh6+ gxh6
4. Nf6#
2. Nxe5+! Ke8
2. … Ke8 3. Ne7#
3. Nxc6 With the double threat of Qd8# and Qe7#. Black cannot prevent both moves at once, but only delay with Qf2+ and g5.
1 – 0

Nh7+ is tempting, but 1.Ne6+ is more appropriate after 1… Nxe6 (if 1…Bxe6 fails to 3. Qe7+ kg8 4. Qe8++, or 1…kg8 2. Qxd8++ or 1…ke8 2.Qe7++)
2.Qe7+ Kg8 3. Qe8+ Nf8 4.Ne7++.
I think my eyes are getting sharper than they were, because now it took me only 5 seconds to see the fabulous move:
1. Nxf7!!
1. … Nhxf7?? 2. Qxd8#
1. … Ndxf7?? 2. Qd8#
1. … Rg8?? 2. Qxd8#/Qe7#
1. … Kg8?? 2. Qxd8#
1. … Ke8?? 2. Qe7#
Slightly longer lasting moves for black are:
1. … Be6?
2. Nxd8+! Kg8?
3. Ne7#
2. … Ke8?
3. Qe7#
2. … Nf7
3. Nxe6+!
gives one of the above mates in next move.
Trying to improve black’s defense:
1. Nxf7 g5 (getting a hole on g7)
2. Qxg5 Bd7?
3. Nxd8+ Nf7 (Kg8/Kg7 Ne7/Qf6)
4. Qe7+ Kg8
5. Qxf7#
1. Nxf7 g5 (looks enforced)
2. Qxg5 Bf5 (looks enforced)
And here I suspect there are still hidden quick mates, but simpler is to gain material with Qxh6+ and Nxh8 before Rxf5.

1.Ne6+ Nxe6 (1…Bxe6 2.Qe7+ Kg8 3.Qe8#; 1…Ke8 2.Qe7#; 1…Kg8 2.Ne7#)2.Qe7+ Kg8 3.Qe8+ Nf8 4.Ne7#.
Sharp eye says Ne6 !
1. Ne6+ Nxe6 (1. … Bxe6 2. Qe7+ Kg8 3. Qe8#) 2. Qe7+ Kg8 3. Qe8+ Nf8 4. Ne7#
A variety that I forgot to look at in my first post is:
1. Nxf7 Bf5
This “counter sack” my look like the only reasonable thing black could try here, but:
2. Qe7+! Kg8
3. Nxh6+ gxh6
4. Nf6#
The best for black I think has to be:
1. … g5
2. Qxg5 (what else) Bf5
This is where you feel there should still be a quick mate, but there are so many different lines…
1.Ne6+ Ne6
2.Qe7+ Kg8
3.Qe8+ Nf8
4.Ne7 mate
1.Ne6+ Ne6
2.Qe7+ Kg8
3.Qe8+ Nf8
4.Ne7 mate
1. Ne6+ threatening the Black Queen as well.
If 1….Bxe6
2. Qxd8 mate
If 1…Nxe6
2. Qe7+ Kg8
3. Qe8+ Nf8
4. Ne7 mate
1.Ne6+! is forced mate
1.-Nd8xe6 2.Qh4-e7+ Kf8-g8 3.Qe7-e8+ Ne6-f8 4.Nd5-e7#
1.-Bc8xe6 2.Qh4-e7+ Kf8-g8 3.Qe7-e8#
1.-Kf8-g8 2.Qh4xd8#
1.-Kf8-e8 2.Qh4xd8#
1)Rf1-f5 Nh6xf5
2)Ng5xh7+ Kf8-g8
3)e4xf5 Bc8xf5
4)Nd5-e7#
A forced variation is
1.Ne6+ Nxe6 (1.-Bxe6 2.Qe7+ Kg8 3.Qe8++, 1.-Kg8 2.Ne7++) 2.Qe7+ Kg8 3.Qe8+ Nf8 4.Ne7++
