White to move. How should White proceed?
2rq2k1/4br1p/1p4p1/p2p1p2/1n6/1BR2Q1P/1P1B1PP1/4R1K1 w – – 0 1
My guess:
1.Rc8 Qc8
2.Re7 Re7
3.Bb4 ab
4.Qd5+ Kg7
5.Qd4+ Kh6
6.Qh4+ Kg7
7.Qe7+ +-
probably not forced though 😉
White wins the exchange, e.g.,
1. Rxc8 Qxc8
2. Rc1 Qd7
3. Bxb4 Bxb4
4. Qxd5
1.Rc8 Qc8
2.Re7 Re7
3.Bb4 ab
4.Qd5+
Heh. That’s the first line I looked at, too. But 4…Kh8 gets Black out of the jam (5.Qd4+ Rg7).
White wins the exchange, e.g.,
1. Rxc8 Qxc8
2. Rc1 Qd7
3. Bxb4 Bxb4
4. Qxd5
Yes, that wins the exchange — for a pawn. Good enough to win?
What doesn’t work for Black is 2…Bc5 (instead of 2…Qd7) 3.Bxb4 Bxf2+ 4.Kxf2 Qxc1 5.Qxd5.
1. Rxc8 Qxc8
2. Bxb4 axb4
3. Bxd5
3..Qf8
4. Qe3 Kh8 and after exchanges White is a Rook up.
4….kg7
5. Bxf7 Kxf7
6. Qe6+ Ke8
7. Rc1 and wins
3… ..Qd8
4. Qb3 Qe8
5. Qe3 Kf8
6. Qe6 Kg7 ( 6… Kg8 7. Qxe7 Qxe7 8. Rxe7 )
7. Qe5+ Kf8
8. Qh8#
7… Kh6 8. Bxf7
7… Rf6 8. Qxe7+ Qxe7 9. Rxe7+
Kh6 , White is a Rook up
3… Qe8
4. Qe3 Kf8
5. Qe6 Rg7
6. h4 h5 ( 6… Qd8 7. Ra1 wins)
7. f4 b5
8. b3 Qf7
9. Qe5 Bf6 ( 9… Qe8 10. Ra1 wins)
10. Qb8+
9. Qc8+ Qe8
10. Qb7 Rh7
11. Rc1 Kg7 ( 11… Qd8 12. Rc8 ) 12. Rc8
egaion, after bxb4 black should reply with Bxb4 so that white’s Re1 is hanging and any exchange that white may win can be taken back. So I dont thin line you mentioned is good one. I think
1.Rc8 Qc8
2.Bxb4 BxB4
3.Rc1 Q—
4.Bxd5 may be the best winning exchange, its kind of same position that probably comes what anon 11:38 suggested. But even in his line one has to play Rc1. If not best this is good shot at win.
I think 1.Bd5, Nd5 2.Rxc8, Qxc8 3.Qd5 is also good.
If 1…Rc3 then 2.Bf7+,Kf7 3. Bc3 and White has won the exchange AND a pawn.

I think 1.Bd5, Nd5 2.Rxc8, Qxc8 3.Qd5 is also good.
Where’s White’s advantage after 3…Qd8? Black’s a healthy pawn up, his bishop is protected, and his rook, although momentarily pinned, is safe from White’s (now missing) light square bishop.
So far nobody’s mentioned my choice:
1.Rxc8 Qxc8
2.Bxb4 Bxb4
3.Qxd5
… which probably means I’ve left a rook hanging somewhere 🙁
1. Rxc8 Qxc8
2. Bxb4 Bxb4
3. Qxd5!
3…….Bxe1??
4. Qxf7+ Kh8
5. Qf6#
3……Qf8
4. Re6!
4……Kg7
If the King stays on g8, 5.Rf6 follows. If 4..Be7, 5.Qe5 wins.
5. Qe5+ Rf6
What else? 5…Kh6 loses to 6. Re8
6. Re8
6……..Bd6
7. Qe2 wins
6……..Qc5
7. Rg8+ Kh6
8. Qxf6 and White is a Rook up and has a mating attack that is impossible to stop( 9. Qh4# is a threat).
Egaion –
1. Rxc8 Qxc8
2. Bxb4 Bxb4
3. Qxd5!
3…….Bxe1??
4. Qxf7+ Kh8
5. Qf6#
3……Qf8
4. Re6!
4.Rd1 looks better, but I don’t see a clear win.
4……Kg7
If the King stays on g8, 5.Rf6 follows. If 4..Be7, 5.Qe5 wins.
5. Qe5+ Rf6
What else? 5…Kh6 loses to 6. Re8
Why does it lose? If anybody’s winning here, Black is, after 6…Re7.
6. Re8
6……..Bd6
7. Qe2 wins
6……..Qc5
6…Qd6, anyone?
7. Rg8+ Kh6
8. Qxf6 and White is a Rook up and has a mating attack that is impossible to stop( 9. Qh4# is a threat).
I think the sequence you want is:
8.Qf4+ Kh5 9.Bd1#

We’re on the same wavelength through 3…Qf8, in any event.
1. Rxc8 Qxc8
2. Rxe7! Rxe7
3. Bxb4 axb4
4. Qxd5+ …
i).
4. … Kf8
5. Qg8++ mate
ii).
4. … Rf7
5. Qxf7+ Kh8
6. Qf6++ mate
iii).
4. … Kg7
5. Qd4+ Kh6
6. Qh4+ Kg7
7. Qxe7+ white is a bishop up
Hm, I just realized anon@11:12 (see first comment) came up with the same analysis already (I really should read everybody else’s comments first, hehe). But yeah, I think this is the best line for white.
Uh, never mind, hehe … I should’ve seen
4. Qxd5+ Kh8!
5. Qd4+ Rg7 and black saves his neck.
This puzzle doesn’t have a clear win.
1. Re5 Rc5
2. Re3 Rb5

Anon, you’ve got an ambiguous move in there — “2.Re3”. Do you mean 2.Rce3 or 2.Ree3?
Assuming you mean 2.Rce3, some of your suggested moves for both sides don’t look like the best moves. To start with, take a look at 1…Bc5 (instead of 1…Rc5).
