The original puzzle stated that Bxc5 is draw and Bf8 is winning.

For me Bxc5 is draw because : 1. Bxc5 Bc7 2. Bb6 Bd6 3. Ba5 Be7 4. Be1 Bd6 5. Bc3 Bb8 6. Bb4 Bc7 7. Ba5 Bd6 8. Kc4 Bb8 9. Bb4 Bc7 10. d6 Bb6 11. Kd5 Bd4 12. Ba3 Ba1 *
I think Bxc5 is winning. Stockfish just does not find the win each time (at equal depth).

Did you actually try to play out a win found by Stockfish? If you go back and forth often enough you will probably be able to let Stockfish lose track of the win, but if you just play against it (by yourself or with the help of another Stockfish instance that does not see the win (yet)) when it is giving a +128 score and don't do takebacks then I doubt that you can keep a draw.
I found the position here (not a lof of details), position number 3 : http://rybkaforum.net/cgi-bin/rybkaforu ... ?tid=26814

After a bit more analyze, I tend to follow Ronald de Man opinon : Bxc5 seems winning too.
I saw the same phenomenon with Komodo 9.2 too, sometimes the score go from +250 to +10, then rise up to +250.
But I've no final conclusion yet.

My private (weak) engine has very similar problems.
Since showing a "mate" score where there is no win is in principle a bug, I strongly suspect the position is winning. (I say "in principle". Unlucky hash collisions can never be excluded and they are not really bugs. But if that were the case here, it should not affect multiple engines.)

I think the win can also be easily proven. It does not seem to take too many moves to break through.

So let's play. I follow your line until move 7 where I play 7.d6.

This is quite interesting, and it seems you're right here.
After forcing 7. d6, score almost immediately rises back to winning.

IIRC, there was no LMR done on advanced pawn pushes as being part of the definition as dangerous, but that was dropped some time ago.
I will try this and report later.

I think Bxc5 is winning.
I agree after a long analysis using texel. Bf8 is a forced mate in 207 moves or less and Bxc5 is a forced mate in 223 moves or less. (If texel could probe 6 men DTM TBs those numbers would most likely be much smaller.)

I have the same "bouncing scores" problem in texel too. It seems there are quite a lot of zugzwang positions deep in the search tree for this position, which makes it hard for engines to solve.

I was about to post that the current vanilla SF backs up Joerg's findings in MultiPV=2 mode up to d=75/95 when a massive fail-high occurred. Three hours later it now looks like this:

It took SF 349342 MN to change the eval on 1.Bxc5 from 0.76 to 128.23. 1.Bxc5 must be a win as well then.

Thank you for the score, Herbert. Wish we had someone of Blackburne's caliber on this board...

After posting the MultiPV=2 analysis (see my previous post) I switched to MultiPV=1, turned off TBs, forced 1.Bxc5 and after 4 hours still got only +128.28 @ d=79/128 (alternating with +128.27 on every odd ply). Should have cleared the hash, dammit!

Now crawling back with a 16-gig hash from a spot towards the end of the PV (which ended in the 6-men TB territory) on Let's Check, currently on White's 16th and #29. As usual, SF periodically discards the PV moves and picks something else <sigh>. With luck I might be done in an hour and a half.

Chessbase's Let's Check gives access to 6-men DTM TBs. That is of considerable help, although getting SF match the mate counts and keep them consistent when backsliding to the initial position is a huge headache. Nevertheless, with a hash big enough (at least 16 GB) and a lot of patience it can be done.

[d]1b6/3kB3/8/1KpPp2p/4Pp1P/5P2/8/8 w - - 0 1

1.Bf8 is mate in 43 (or 42)
1.Bxc5 is mate in 50


Below are the sequences used for backsolving, each followed by a multi-hour analysis of the initial position without clearing the hash
(11 cores and threads / 32 GB hash / TBs off)
