Could you or somebody else please post convincing analysis that 15...Nf3+ wins?
I've analyzed it a little with various programs but haven't found a clear win in
all variations. I have to leave now, but this is what I have so far:
15...Nf3+ 16. gxf3 Qh4 17. fxg4
[17. Re3 f4 18. Re5 Bh3 19. Nd2 Bxe5 -+]
17... Qxh2+ 18. Kf1 f4 19. f3
[19. Nd2 Qh1+
(19... f3 20. Nxf3 Qh3+ 21. Kg1 Qxg4+ 22. Kf1 Qh3+ =)
20. Ke2 Rae8+ 21. Ne4 Rxe4+ 22. Be3 Qg2 23. Kd3
(23. Kd1 fxe3 24. fxe3 Qxg4+ =+)
23... fxe3 24. Rxe3 Rxg4 =+
(24... Rxf2 25. Qxf2 Rxd4+ 26. cxd4 Qxf2 =)
(24... Ref4 25. f3 Qh3 =)]
19... Qh1+ 20. Kf2 =
[20. Ke2 Rae8+ 21. Qe4 Rxe4+ 22. fxe4 Qxe4+ 23. Kd1 Qg2 24. Bc2 Qxg4+
25. Kd2 Qg2+ 26. Kd1 f3 27. Bd3 f2 28. Rf1 Rf3 29. Be2 -/+]
