Here is the solution for the first puzzle. The first move is obvious. The rest requires precise moves.
1…Ne5+
2. Rh2+ Kg3
3. Rg2+ Kf3
4. Rg5 Ra1+
5. Rg1 Rxa7
6. Rf1+ Kg3
7. Rg1+ Kf2
8. Rg2+ Kf3
9. Rg8 Ng4
10. Rf8+ Kg3
11. Kg1 Ra1+
12. Rf1 Ra8
13. Rc1 Nh2
14. Rc3+ Nf3+
15. Kf1 Ra2
16. Rc2 Nd2+
17. Ke1 Rxc2
18. Ke2 Rb2
Of course I understand that it isn’t efficient but this my understanding of the play.
At a glance, the biggest inaccuracies I see are at move 7 for black where 7. ….Kh3 shortens things considerably, and later at 9. ….Ng4 where it is better to play almost any rook move on the 7th rank that doesn’t go to or cross the e-file (i.e. Rb7-c7-d7). However, I think your line is winning at all points, but you should check it with the Nalimov tablebase in detail. However, here is the link to the previous time this puzzle was posted here: Link.
Here is the solution for the second puzzle. The problem is amazing. At first I was fixated on Rd4. I had to think outside the box to find the first move. I spent one hour to find it. After that I had difficulty in finding the second move.
1…Kg7
2. Kc3 h5
3. Rg5 exf4
4. gxf4 Rxf4
5. Ra5 Rxh4
6. Kd3 Rh3+
7. Ke4 Ra3
8. Kf4 a3
9. Kg5 Kf7
10. Kf4 a3
11. Kf3 a2
12. Kg2 Ke6
13. Kf2 h4
14. Kg2 h3+
15. Kh2 Kf6
16. c3 g5
17. Ra6+ Kf5
18. Ra8 g4
19. c4 g3+
20. Kxh3 Rh1
21. Kxg3 a1+Q
22. Rxa1 Rxa1
It’s a winning posion for black.
Well done! I had a lot trouble with this puzzle the first time, too. Tried everything else for all intents and purposes before I began investigating the moves to prevent white from playing fe5 with check.

The puzzle had been posted once before on April 8th, 2008 on Susan’s site, but I had not yet become more than an occasional reader at that time and missed it. Everyone struggled with it both times.
Here is the solution for the third puzzle. It was a very easy puzzle.
1. Kc3 Bf7
2. Rd8+ Kb7
3. Rd7+ Kc6
4. Rxf7 Kd5
5. Re7 Kd6
6. Re4 Kd5
7. Kd3 Kc5
8. Rd4 Kb5
9. Rc4 Kb6
10. Kc3 Ka5
11. Rb4 Ka6
12. Kc4 Ka5
13. Kc5 Ka6
14. Rb5 Ka7
15. Kc6 Ka6
16. Rc5 Ka7
17. Kc7 Ka6
18. Rd5 Ka7
19. Ra5#
I also found this one easy at the time. The bishop has no quick path back to his king’s protection after 1.Kc3.
Here is the solution for the fourth puzzle.
