That's a pretty one. Black can choose to lose three different ways:

1. Rh7+ Kxh7 2. Qe7+ Rf7 3. Qxf7+ Kh8 4. Qg7#
1. Rh7+ Kxh7 2. Qe7+ Kg8 3. Qg7#
1. Rh7+ Kxh7 2. Qe7+ Kh8 3. Qg7#

Computer Analysis:
1. Rh7+ Kxh7 2. Qd7+ Rf7 3. Qxf7+ Kh8 4. Qg7#

There's also a fourth way (Kg6) for Black to lose.

Black deserves what's coming for allowing that aggressively-posted
knight.

1. Qb8+ Qxb8 2. Nxd7+ Ke7 3. Nxb8
1. Qb8+ Kf7 2. Qxc7 Kxf6
1. Qb8+ Qc8 2. Nxd7+ Kf7 3. Qxc8

With best play Black loses a bishop. Inferior responses will cost him a
Queen.

Computer Analysis:
1. Qb8+ Qxb8. 2. Nxd7+ Kg7 3. Nxb8

Well, 1. Ne7+ is a great start. There are many continuations, but using
checks it's pretty easy to get white's knight into a good position and
snatch a pawn:

1. Ne7+ Kh6 2. Nf5+ Kg6 3. Rd6+ 4. Kf7 Rxb6

Computer Analysis:
1. f5+ Kg5 2. Rxc7 Kf4!?
1. f5+ Kg5 2. Rxc7 Nxc7 3. Kg3 b4 4. h4#

White can win a rook by threatening mate! And I settled for a pawn.

This one is hard to visualize.

1. g6 Qe2 2. Bxh3 gxh3 3. Nf3+ Kh1 4. Qh4 with Qxh3# coming soon?

Computer Analysis:

My solution fails to score a win if White plays 3. Kg2, it only scores
a draw.

1. Nf3+ gxh3 2. g6 fxe4 3. gxh5 exf5

Winning the Queen! These are the same moves I suggested, but in a
different order, which makes the attack much more devastating.

1. Nf5+ King can go to... Kf3, Kf1, Kg1 Too many branches for me to
solve in advance.

Computer Analysis:
1. Nc2+ Kf3 2. Ne1+ Kf4 3. Nd3+ Kf3 4. Re3#

Nice. Nf5+ doesn't score.
