1-Bh7 Kh8 2-Bc2 Kg8 3- Rg2 Bxg2 4-Bh7 Kh8 5-Bg6 Kg8 6-Qh7 Kf8 7-Qf7++
cute but kinda obvious:
Bh7+ Kh8
Bc2+ Kg8
Rg2+ Bxg2
Bh7+ kh8
Bg6+ Kg8Qxf7 mate
1. Bh7+ Kh8
2. Bc2+ Kg8
3. Rg2+ B:g2
All this to get the B off the a2-f7 diagonal!
4. Bh7+ Kh8
5. Bg6+ Kg8
6. Qh7+ Kf8
7. Qf7#
1. Bh7+ Kh8
2. Bc2+ Kg8
3. Rg2+ Bxg2
4. Bh7+ Kh8
5. Bg6+ Kg8
6. Qh7+ Kf8
7. Qxf7#
There is an easy perpetual check with Bh7+ Kh8 Bf5+ etc.
Trying 1. Bh7+ Kh8 2. Bc2+ doesn’t seem to help since the bishop and queen control g2 and we can’t get the white rook there.
Best way to play for a win seems to be
1. Bh7+ Kh8 2. Bc2+ Kg8 3. Qh7+ Kf8 4. Qh8+ Ke7 5. Re2+ etc.
1Bh7ch kh8 2Bc2ch kg8 3Rg2ch bxr 4Bh7ch kh8 8Bg6ch kg8 9Qh7ch kf8 10 Kf7 mate
need to block the black rook and black bishop so I’d try:
1. B-h7+ K-h8
2. B-c2 K-h7
so we’ve blocked the rook from interfering when we give check
3. R-g2 Bxg2
now Black’s Bishop is unable to protect
f7
4. B-h7+ K-h8
5. B-g6+ K-g8
6. Q-h7+ K-f8
7. Qxf7 mate
This one is easy once you get the idea of deblocking the R. So Bh7+, Kh8, Bc2+ and now the rest is simple.
White can draw with Bh7+ and make repetition of moves there after for a draw.
I tried looking for a win here but I am not a GM failed to see one
Bh7+ / Bc2+ / Rg2+ / Bh7+ / Bg6+ / Qh7+ / Qf7# (black has always just one move)
I don’t see the correct solution yet, but I guess I’m close when I see:
1. Bh7+ Kh8
2. Bc2+ Kg8
3. Rg2+ Bxg2
4. Bh7+ Kh8
5. Bd4+ Kg8
6. Bxa8 Bxa8+
This gained queen for rook and bishop, alas this isn’t enough to save the game for white, so there must be an improvement somewhere, a winning line for white.

2. ♗c2+ ♚g8
3. ♖g2+ ♝xg2
4. ♗h7+ ♚h8
5. ♗g6+ ♚g8

1. Bh7+ Kh8 2. Bc2+ Kg8 3. Rg2+ Bxg2 4. Bh7 Kh8 5. Bg6+ Kg8 6. Qh7+ Kf8 7. Qxf7#
Bh7+ kh8
Bg6+ kg8
and white forces draw by repetition of positions.

Bh7+ and then Bc2, Rg2 to deflect black’s bishop.

Well, if only that Black bishop weren’t protecting f7, then 1. Bh7+ Kh8 2. Bg6+ Kg8 3. Qh7+ Kf8 4. Qxf7#. And if only that Black rook and bishop weren’t where they are, then White could play 1. Rg2#. Combining these 2 ideas, deflecting the Black bishop from protection of f7, and interfering with the Black rook’s attack on g2:
1. Bh7+ Kh8 2. Bc2+! Kg8 3. Rg2+ Bxg2 4. Bh7+ Kh8 5. Bg6+ Kg8 6. Qh7+ Kf8 7. Qxf8#

Wow what a cool position. White can do better than a perpetual check and indeed can mate the black king.
1.Bh7+ Kh8
2.Bc2! this move interferes with the pin on the d2 rook
2… Kg8
3.Rg2+ Bxg2 which not only frees up the c2 bishop but also leaves its protection duties on f7 and this allows
4.Bh7+ Kh8
5.Bg6+ Kg8
6.Qh7+ Kf8
