Waiting already 6 minutes in depth 33 now without solution, don't know, how long I'll let it run.
Stopped after 20 minutes without solution.

At least McCain is rather good in Backwarding the lines after the Queen-sac, which isn't so for all engines, even modern ones, neither. E.g. komodo does better with switched off nullmove. There's much Zugzwang in several lines. Accordingly McCain does better with switched off nullmove here too.

Here's McCain with Analysis Contempt and nullmove switched off after Backward to the original position before the sac:



Analysis by McCain v10.1:

24.Qxe5 fxe5 25.Rf1 Rc7 26.Bd1 b5 27.Bb3 Rc4 28.a4 a6 29.Ba2 Qe7 30.b4 Qa7+ 31.Kg2 Qg7 32.Bxc4 bxc4 33.Bxg7 Kxg7 34.Rf7+ Kh6 35.a5 Re8 36.e7 Kh5 37.Rxh7+ Kg4 38.Rf7 Kh5
+- (7.19 ++) Depth: 44/77 00:05:10 8760MN

24 threads of 12x3GHz, 32G hash.
Won't be surprised if NN-MCTS engines like Lc0 gets this puzzle quickly. Most of its exciting won games involved trapped pieces against AB engines.
Lc0 would detect the trapped pieces on this position and the useless Q of black since it just passively defends f8 square.
I told my wife that a husband is like a fine wine; he gets better with age. The next day, she locked me in the cellar.

Code written by Günther Demetz ( pb00068 on Github ) and Michael Stembera (mstembera on Github) in a collaborative effort by these two extremely talented and valued Stockfish programmers led to to this latest improvement in McCain.

First I knew it was getting close when McCain was able to solve a precursor position :
I ran it twice and it was solved both times, although the first run was quite a bit shorter
All of the runs below were straight runs, clean starts and no back and forth on a 2010 MacPro with 12 cores and 16 GB hash. 23 threads were used for each run.

Latest McCain Code is available on Github for McCain 10.1 , exe's will be available within a few days.

https://github.com/MichaelB7/Stockfish

The master branch has the code - as a reminder , from the one source, you can build McCain, McCain w Mate finder, Stockfish with features ( Cerebellum book, play by elo , Stockfish with Matefinder and straight dev-stockfis. The various makefile examples are also on Github and include the bench nodes for each version. The Matefinder code is directly from Joe Ellis' Matefinder fork but it does not include all of his Matefinder patches. All changes from dev-Stockfish code are marked with "#ifdef xxxx" and source attributed.

Also there were few bug fixes as well, none by the SF team, these were all my doing.

Vondele found a bug in the use of VALUE_MATE_IN _MAX_PLY when having tablebases on board. Looks like not really a fault of vanilla Stockfish code but more of the later added tablebase code in Stockfish in my opinion. But Mikes version probably does not have the bugfix, Stockfish Dev does, as of today. Congrats for finding this to Vondele!
Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

Oh, I missed that, sorry, I saw 'tbhits' and assumed that means they are installed, but doesn't have to be of course. Shredder GUI in its output only mentions them if there are actually tbhits that's probably what confused me. I am curious if simple mates + finding shortest matepath + tablebases now go a bit better after the bugfix but that probably is not changed by this bugfix. I never use them although on this old system I do have Shredderbases that the GUI could use and Scorpio's bitbase too stil, for old Toga.

Waiting already 6 minutes in depth 33 now without solution, don't know, how long I'll let it run.
Stopped after 20 minutes without solution.

At least McCain is rather good in Backwarding the lines after the Queen-sac, which isn't so for all engines, even modern ones, neither. E.g. komodo does better with switched off nullmove. There's much Zugzwang in several lines. Accordingly McCain does better with switched off nullmove here too.

Here's McCain with Analysis Contempt and nullmove switched off after Backward to the original position before the sac:

Won't be surprised if NN-MCTS engines like Lc0 gets this puzzle quickly. Most of its exciting won games involved trapped pieces against AB engines.
Lc0 would detect the trapped pieces on this position and the useless Q of black since it just passively defends f8 square.

Waiting already 6 minutes in depth 33 now without solution, don't know, how long I'll let it run.
Stopped after 20 minutes without solution.

At least McCain is rather good in Backwarding the lines after the Queen-sac, which isn't so for all engines, even modern ones, neither. E.g. komodo does better with switched off nullmove. There's much Zugzwang in several lines. Accordingly McCain does better with switched off nullmove here too.

Here's McCain with Analysis Contempt and nullmove switched off after Backward to the original position before the sac:



Analysis by McCain v10.1:

+- (7.19 ++) Depth: 44/77 00:05:10 8760MN

24 threads of 12x3GHz, 32G hash.
Won't be surprised if NN-MCTS engines like Lc0 gets this puzzle quickly. Most of its exciting won games involved trapped pieces against AB engines.
Lc0 would detect the trapped pieces on this position and the useless Q of black since it just passively defends f8 square.

Waiting already 6 minutes in depth 33 now without solution, don't know, how long I'll let it run.
Stopped after 20 minutes without solution.

At least McCain is rather good in Backwarding the lines after the Queen-sac, which isn't so for all engines, even modern ones, neither. E.g. komodo does better with switched off nullmove. There's much Zugzwang in several lines. Accordingly McCain does better with switched off nullmove here too.

Here's McCain with Analysis Contempt and nullmove switched off after Backward to the original position before the sac:

Won't be surprised if NN-MCTS engines like Lc0 gets this puzzle quickly. Most of its exciting won games involved trapped pieces against AB engines.
Lc0 would detect the trapped pieces on this position and the useless Q of black since it just passively defends f8 square.
