Hi again Leonid!

It took my program 45 minutes ... phewwwwwww!
Here's the line, a mate in 12:

1. Qxa7+ Qxa7 2. Qxa7+ Kxa7 3. Qeb6+ Ka8 4. Qgxb7+ Qdxb7 5. Qxb8+ Qxb8
6. Qxb8+ Qxb8 7. Q6a5+ Na6 8. Qaxa6+ Qa7 9. Qg8+ Bf8 10. Qxf8+ Qe8+
11. Qfxe8+ Qc8 12. Qxc8x

I think I'm going to skip your next problem, that will be too difficult
for me ;)
