Re: tcec practical hard mate test

Here are 9000 TCEC checmates or easy wins for Black, collected via the following query:

select t.Epd + ' ' +
dbo.opcode_format('bm', bm) +
dbo.opcode_format('c0', Engine) +
dbo.opcode_format('ce', ce) +
dbo.opcode_format('acd', acd)
, * from Tcec t where ce between 10000 and 32758 and dbo.ChessmanCount(Epd) > 9 and Epd like '% b %' and result = '0-1' order by ce desc



I chose to limit mate depth to filter out the super easy ones and also require ten chessmen so that there is not a simple tablebase lookup
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.

I cannot find this game:

with this Epd r7/5pkP/1n3Np1/3P2P1/2n1PK2/1R6/p7/2R5 w - - 0 1 bm Ra1 dm 18

Could I get the PGN for that game?

I did not find that exact position in the game, but it was very similar to these two:

You are right
It seemd that I went forward and backward in analysis and gave the wrong position.

I gave more time for slowchess and slowchess found that Ra1 is mate in 18

Here is the analysis with 2 options after Ra1 and after some hours

7R/2k1p2P/r2rP3/8/3p1R2/8/2P2p2/2K5 w - - 0 1 bm Rc8+ dm 26
Ran this with HOUDIDIT with Nalimov tables for 9 hours. 6 threads, 16G Hash. Other technical info in signature.

FEN: 7R/2k1p2P/r2rP3/8/3p1R2/8/2P2p2/2K5 w - - 0 1

Found a Mate in 24. I ran it as PV=1. After this run, I changed to PV=2 (to check for duals) and so far the best 2nd move is Rb8 = M31 @41ply.

I thought I read in another post that Chest had this as M14 ?? If so, then why isn't that indicated as the real "dm" value?
