This one’s relatively straightforward.
1 Bg7+
if Bxg7 then 2 Qxg7 mate
if Kg8 then 2 Bxf6++ followed by 3 Qg8 mate.
Me? I’m just a patzer
Well, Bg6 should provide white with an advantage:
1. Bg7 Kg8
2. Bf6 Rg4
3. Rg4 Kf8
4. Bd8 and white is up an exchange and pawn (winning a rook with this tactic).
1. Bg7+ (a) Bxg7
2. Qxg7#
1. … (b) Kg8
2. Bxf6+ Kf8
3. Bxd8 we can stop now

Doesn’t Bg7+ win?
1. Bg7+, Kg8 (Bxg7, Qxg7#)
2. Bxf6++, Rxg4
3. Rxg4+, Kf8
4. Bxd8, Rc8
5. Bg5, Nxd3
And Black cannot win against the White’s attack with two rooks and the bishop
Well, white is down two pieces with just a pawn to show for it (and a good position). He can always draw the game by 1. Qg7+ Bxg7 2. Bxg7+ Kg8 3. Bh6+ Kg8 with a perpetual. So the question is, can he win from here?
Suppose he plays:
1. Bg7+ Kg8 (1… Bxg7 2. Gxg7#)
2. Bxf6+ Rxg4
3. Rxg4+ Kf8
4. Bxd8 Rc8
I don’t like 4… Rd7 for two reasons:
1. It cuts off the black king’s escape route – eg: 4… Rd7 5. Bf6 Nxd3 6. Rg7 Re7 (6… Rc7? 7. Rxh7 Ke8 8. Rh8+ Kd7 9. Rd8#) and black is about to lose more material, and
2. It retains control of the c-file which is black’s only hope of a counterattack – play Nxd3, Rc2 with a good attack along the second rank
5. Bh4
This last move pre-empts black’s plan of such a counterattack. Now he has no answer to 5… Nxd3 6. Rd4 (if it were not for the bishop, he had 6… Nf2+). Now he has pretty much run out of steam, and is an exchange down (from being two pieces up 🙂
1. Bg7+ Kg8
(1. .. Bxg7 2. Qxg7#)
2. Bxf6+ Rxg4
(2. .. Kf8 3. Qg8#)
3. Rxg4+ Kf8 4. Bxd8
