Funny.
In this position (I didn't try the other one) my engine says:

Still two good moves ??
OK, add a black pawn on h5 to prevent B(-c2-d1)-g4:
05 00:00:00 - 0.97 G1-F2 C8-B7 D5-D3 F4-F3 G2xF3
06 00:00:00 - 0.97 G1-F2 F4-F3 G2xF3 C8-B7 D5-D3 A8-F8

00:00:00 - 1.15 C2-D1 C8-A6 D1-F3 A6xC4 D5-D2 A8-E8 F3-C6 D7xC6 E1xE8
00:00:01 - 1.14 D5-D2 C8-B7 D2-E2 A8-H8 E2-E7 F7xE7 D6xE7
08 00:00:02 - 0.84 D5-D2 C8-A6 C2-E4 A8-H8 E4-D5 F7-F6 E1-E7 D7xD6 D2-E2
09 00:00:06 - 0.91 D5-D2 C8-B7 D2-E2 D7xD6 E2-E6 D6-D7 E6xB6 B7-C6 C2-E4
A8-C8
10 00:00:19 - 1.14 D5-D2 C8-B7 D2-E2 B7-C6 E2-E7 F7xE7 E1xE7 D7xD6 E7xH7
F4-F3 G2xF3 D6-E5 C2xG6 C6xA4 G6xH5
00:00:51 - 0.70 C2xG6 H7xG6 E1-E7 F7xE7 D6xE7 D7xE7 D5-D8 E7xD8 H6-H7
G6-G5 H7-H8D D8-C7 H8xH5 C8-B7 G1-F2 A8-D8 H5xG5
11 00:01:06 - 0.29 C2xG6 H7xG6 E1-E7 F7xE7 D6xE7 D7xE7 D5-D8 E7xD8 H6-H7
G6-G5 H7-H8D D8-C7 H8-E5 C7-B7 E5xG5 C8-D7 G5-E7 B7-C7
Now Bxg6 is the one and only move, I guess.
I don't know if it wins ;)
