# A Mind-bending Mate in 3

I spent an entire day trying to solve this puzzle in 2014 before giving up and looking up the solution. Can you solve it?

No. 1-5

The key move is the second one. Alena gave the key line above when black plays 1. ...Qf4- 2.Kb6 is the only solution after that point.

Looks like 1. Rh4 threatening 2. Nf2 dbl ch and mate does the trick.

- Rh4 Qxh4
- Qxb2

and White is going to make with 3. Qb4 or 3. Qxe5

It is an amazing move- the second one- it opens the white king to 7 different checks on black's second move, and all 7 are answered with mate. Unfortunately for me, I never really focused on 1.Rh4, and never really gave myself a good chance to find the solution.

Another 15 minutes

V-2

1.Rh4! Qxh4

2.Qxb2 Qxh6

3.Qxe5#

V-3

1.Rh4! Qxh4

2.Qxb2 Qxg4

3.Qb4#

At first I have found mate in 4. Then I guessed how to mate in 3.

I'm very surprised but it took me 30 minutes. At first I got stuck on Qb1.

1.Rh4! Qf4

2.Qb1 b5

3.Rd1+ Nd3

4.Qxd3#

After that I corrected my solution and got mate in 3.

1.Rh4! Qf4

2.Kxb6 g2

3.Nf2#
