The next (my liked) great study seems to be in troubles.
Evgeny Somov-Nassimovitsch
“64” 1939
 (= 7+4 )
draw
solution:
1.Re7 Qxe5 2.f8Q+ Kg1 3.c3 Qe1+ 4.Bb1 Qxc3 5.Rg7+ Bxg7 6.Qf1+ Kxf1 7.Bd3+ Ke1 8.bxc3 Kd2 9.Bc2 Kc1 10.Bb3 Bxb3 stalemate
After 1…Bd5 there are possible:
a) 2.Rd7 Bf3 3.Re7 (3.Rd3 Kf2 4.Rd2+ Kg1 -+) Ke2 4.Re8 Bd5 5.b3(c4) Bxf7 6.Bxf7 Kd2 -+
b) 2.Re8 Ke2 3.b3(c4) Bxf7 4.Bxf7 Kd2 -+
and my proposition to save it
c) 2.c4 Bxc4 3.Re8 Bxf7 4.Bxf7 with a complex position and I would like to believe that White can gain a draw here.
Maybe somebody can help me.

The study is correct. Sadly I lent the book to someone where there is talked about this but I try to get the analysis from him.
For now I don't see how black wins after 1...Bd5 2.Rd7 Bf3 3.Rd3 Kf2 4.Rd2+ Kg3 5.Rd3 Kg4 6.Bh5+ Kxh5 7.Rxf3 Qf8 8.Rf1.
 (= 6+3 )
You give 4...Kg1 instead, but I'm not sure if that wins either: 5.c3 Qf8 6.Rd3! or 5...Qh6 6.Rd3! gives black a hard time, even though the bishop can't be taken yet - how should he improve his position? (for example after Bxe5 7.Kb1)
 (= 6+4 )
Of course, common sense tells us this must be won for black - but is it?

Maybe, if the black Queen would be a queen not the Terminator
As I mentioned above, after the two possible moves (1…Bd5) 2.Rd7 and 2.Re8, Black wins.
The move 2.c4 (Bxf7 3.Bxf7) gives a practical chance to get a draw.
An analyze, by moves (after 2.c4), could be very difficult and unnecessary.
A computer software is not of use for that too.
The following crucial position is won for Black.
 (= 4+3 )
no matter who moves
WB is captured after each move.
If it is impossible to avoid this position, Black will win. How can White keep Black back? I don’t see.

Ok, then the position given by me (you) also is won for black.
