White to move. How should White proceed?
Source: ChessToday.net
1. a6 and if 1… b6 then 2. bxc5
ba6 3. bxb6 ab 4. rxb6 bxc4 5. qa1 qa7 6. qxa7 kxa7 7. rb7 ka8 8. rxe7 +-
I tend to 1.Bxc5 dxc5 2.d6, attacking the black queen while simultaneously adding pressure to b7 by the white bishop. Did not calculate any further but looks pretty much winning to me.

but deviations are possible of course (3… bd7, 4… qc8) it is not that clear. i need pieces or to calculate this 🙁
Hang on, 1.a6 seems to be even stronger than my previous suggestion. On 1…b6 white would sac 2.Bxc5 and black is lost. Thus, black must play 1…Rd7 but that move looks so ugly – and even then 2.Bxc5 looks strong. I actually prefer that over my earlier suggestion…

How about
1. Rxc5 dxc5
2. d6 Qxd6
3. Rxb7 Bxb7
4. Bxb7+ Kb8
5. Ba6+ Kc7
6. Qb7#
Does anyone see any flaws in the above sequence?
What about 2…R:d6
I think about 1.Rb6, but I still can not find the solution.
Good point. Was trying to lure the Queen away from c7. Perhaps we can combine the last two ideas:
1.Rxc5 dxc5
2.a6
Creating a discovery check threat if 2.. b6
If 2.. Rd7 then 3.d6
There are too many ways to a win.
In a game I would immediately play 1. a6 and a line like given by Anon1
I am not sure that Anon1’s solution is a clear win yet. Black could play 4..Qa7 instead of 4..Bxc4:
1.a6 b6
2.Bxc5 Ba6
3.Bxb6 axb6
4.RxB6 Qa7 (pinning the rook)
5.Kh1 Bxc4
and white has just traded a bishop for two pawns. Doesn’t seem like a clear win to me.
to 5:06:00
why play 5. kh1? 5. ra2 and 6. r2xa6 +-
______________________
i dislike rxc5 because it reduces the number of the attackers of b7 pawn. for example 1. rxc5 bc 2. a6 (2.d6 rxd6 -+) rd6 and the pawn is well protected (3. ab bxb7 and now waht?)
________________________
1. rb6 is a nice trap for a 1+0 game (1… ab??), but what threat does it exactly create? black can now increase the number of the defenders of the frigging pawn: 1… rh7 (2 bxc5?? qxc5+ -+)
___________________________
bottom line: i do not see “many ways to win”. 1. a6 probably wins (if nobody finds a refutation) and 1. bxc5 should be good to: black cannot capture and white creates other threats (bb6, bf2 and c4-c5)
I like this line:
1.Bxc5,dxc5
2.d6, Rxd6
3.Bxb7+ and win.
1.Bxc5 dxc5 2.a6!
1. Bxc5 dxc5
2. d6 Rxd6
3. Rxb7 Bxb7
4. Qxb7 Rxb7
and W wins.
