White to move. How should white proceed?
1. Qb8+ Rd8 *
2. Qb5+ Ke7
3. Qxc5+ Ke8 **
4. Qc6+ Ke7
5. Qc7+ Kf6
6. Nf3+ e5
7. Qxe5#
*
if 1. Qb8+ Qe7, 2. Nc6#
**
if 3… Kf6 (instead of 3… Ke8)
4. Nd7#
1. Qb8+ Rd8
2. Qb5+ Ke7
3. Qb7+ Kf6
4. Qxf7+ Kg5
5. Nf3+ Kh5
6. g4+ Kxg4
7. Qe6+ Kf4
8. Qe5+ Kg4
9. Qg5+ Kh3
10. Qg3#
Am sure there is a much shorter variation.
I could get the initial moves right but took some time for the subsequent moves. White is under the threat of Qd1 and must move quickly
1.Qb8+ Rd8
(1…Ke7 2.Nc6#)
2.Qb5+ Ke7
3.Qb7+ Kf6
(3…Ke8 4.Qxf7#
4.Qxf7+ Kg5
5.Nf3+ Kh5
(5…Kg4 6.Qxe6+ Kh5 7.g4+ Kh6 8.g5+ Kh5 9.Qh3#
(5…Kh6 6.Qf4+ Kh5 7.Qh4#)
6.g4+ Kxg4
(6…Kh6 7.Qf4+ g5 8.Qxg5#)
7.Qxe6+ Kf4
8.Be5+ Kxe4
9.Bxh8+ Kf4
10.Qe5+ Kg4
11.Qg5+ Kh3
12.Qh4+ Kg2
13.Qg3#
I think I posted the solution of this to the other blog
