Sorry, silly me. That line I gave was just a quick glance at the diagram without engine assistance and without much thought.
Didn't anaylize this position deeply even before. I just joined at Page 14, but if you click on Page 6 of this thread,
your Ne3 line was already answered there by the author of this thread.

p.s. MikeB and I are not the same person, MikeB is a powerful programmer.

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.

I think I am doing more here in answering you, George, but as you asked with 4 months apart...
Well giving you 4 months for finding a move is not too short isn't it? :D

So do you have a specific move that wins for white in this position?
[d]1r3rk1/5p2/2b1pPpR/q2pP1N1/p1pP4/npP5/1P2BB1P/3R3K w - - 2 27

I really hoped this position to be a good testposition(white to win) but i'm afraid it is just a draw, but perhaps you know better, that's why i'm asking.
Which position should I consider first, this one, or the one with Louis and Smyslov?

As you rightly say, there are innumerable lines.

Obvious first moves for white you might want to consider are Rg1 (which I think is no good), Rh3, and Be1 (which I preferred initially).

Besides, it is possible that lfirst moves like Rh7 and Bh5 are also in store for some surprise.

As soon as I have a breath of fresh air, and in case you do not find the solution, I will tell you what to play.

In the meantime, why do not you be so kind to do a fair share of the work and refute all of the above suggested moves?

Easy task, is not it? :D

Eagerly waiting for your analysis, once you refute all of them, I will tell you the answer.
This position is an easy win for White - as my new engine , named McCain, a close McBrain relative, dedicated to the late Senator John S McCain, a true American hero and former POW held for 5 -1/2 years by the North Vietnamese during the Vietnam war after he was shot down on a bombing mission, finds it in 49 seconds on a Mac Pro.

This is Mate in 38 moves. Maybe a little bit shorter, but the distance to Mate was not entirely stable. I am fairly certain it is not much shorter, maybe a M37. After 1. Bg1 Qxc3 Kaissa now gives

I was hoping to get confirmation of a M38 at depth 96, but with 512 Mb it was not entirely stable and there was a 800 min delay between depth 95 and 96. This is not exactly the official Kaissa Iv in case anyone wants to verify :) (it is a one thread result, so deterministic. There is a slight difference in the code from Kaissa IV though). But the difference is not very large.
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.

Using the back and forth method, i.e., playing out the position and various lines until mate is found, and then backing up the original position, I am now seeing a mate-in-35. It would take much longer from a clean start :

I was hoping to get confirmation of a M38 at depth 96, but with 512 Mb it was not entirely stable and there was a 800 min delay between depth 95 and 96. This is not exactly the official Kaissa Iv in case anyone wants to verify :) (it is a one thread result, so deterministic. There is a slight difference in the code from Kaissa IV though). But the difference is not very large.
I think this is one of the positions being discussed in this thread. So far the best Cfish can do (direct search) is mate-in-37.

Hi Mike and Louis,

Thanks for the feedback and added analysis, it goes a bit quicker on your machines than with one thread on mine :) I think the Mc Cain version of Brainfish (Off topic this reminds me a bit of Michael Caine, which is not the actor's real name but inspired by "The Caine Mutiny" a good film with Humphrey Bogart. So there we are back to Caines in the Navy again) is right that it is Mate in 33, at least I can confirm that the PV after 11 moves from Mike B. indeed is M22 now:

But a direct search has problems finding the shortest Mate, even in a direct search it seems with the Mc Cain and even at your depths Louis. It must be because of LMR but at this depth you would not expect this much of an effect of LMR horizon problems. Quiet moves like 12. Be1 are hard here like 1. Bg1 in the original diagram pos.

Thanks guys!
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.

Well, it needs no proof that Stockfish is a great program, and reaches incredible depths. But. There's a but.
It prunes massively, and treating it like a god or oracle of chess is completely crazy, as this example proves (as would looking at the source code).
Just how much Stockfish misses in getting to the depths it does, may (or may not) be shown by NN engines at some point, although we're not there yet (if ever). It's really, imo, the only interesting aspect left in computer chess: just how many holes are there in the current fast AB programs. And proving the "chess is all tactics" and "Stockfish is god" brigade to have been completely wrong. It may be that Stockfish developers can continue improving, or it may end up being shown that testing against self and similar brothers and sisters is climbing up the wrong hill.

Yes, a pair of good points. I wonder often if, on modern high-end hardware and LTC, the amount of pruning/reducing is actually too much. And, of course, this is related to your second point---Stockfish development is tested by self-play at very short time controls. But how else to do statistically meaningful testing?
