Post by Hobacle »

[pgn][Date "2023.07.29"] [SetUp "1"] [FEN "k7/3PBB1R/1QR1P1NQ/3NP1KR/1RQ4R/5r2/8/8 b - - 0 1"] [PlyCount "1"] 1... Rf5+ [/pgn]

And wRc6->wPc6 may be a #213.

So far depth 70 is promising.
The original position key move is verified and there is a high score.
But intermediate positions have a draw score.

I think ply 80 is going to take a while.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

These 40 are probably the most interesting.
These are the positions where the computer move is different than the suggested pv move:

Quite a bit of improvement from the ply 80 run.

Re: White mates in 205?

It is a funny puzzle. Not so much "how does white win in 205" but "how does black lose in 205".

Or maybe a combination of both. I don't think it will be easy to show that 205 is optimal...

Re: White mates in 205?

Post by Eelco de Groot »

trying to verify the solution from Hobacle, going backwards from Move 205, my computer does not have large enough memory I think but also Crystal 6 had some problems remembering what it had just found.

Here it goes wrong in three best moves Multi PV, the solution is lost:

[d]k7/7R/2R1P3/8/1R6/8/5r2/5K2 w - - Engine: Crystal 6 PMT (512 MB)

92 7:29 0.00 197.Kxf2 (702.750.992) 1563

It is/was not uncommon in the past with Stockfish that solutions or best moves got lost going backwards, because Stockfish does not follow hash entry in the PV nodes without doing a new analysis of anything it finds in the hash table, here (going backwards) that can be a drawback.

Trying 'Incognito',new Stockfish modification from Eduard and Ivan, it does not have exactly this problem, at least not so far (have not gone up in the solution).

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.

Re: White mates in 205?

The issue is that the solution is currently beyond the scope of the engine. With a stack & ply limit of 246, one has a max search depth of 123 full moves. Generally, this isn't much of an issue, but in this case...

There isn't much to be done regarding max depth without reworking the TT a bit, which I don't really want to get into right now. But extending the stack and PV size is doable, and to that end a modified version of Crystal dev *appears* to hit the solution at a depth of 144 with SD of 408, 32GB, 1-thread, failing high up to +90.90.

Running a further modified version now to see if it can actually resolve the mate.
