Cfish is best for me here too, tried it only with Forward-Backward. Xiphos has a very fine mating- search too and was second best of a few engines I tried backwarding this.
I don't see, how NNUE should help here, it simply slows down the same kind fo search, doesn't it?

As a matter of fact I don't see much sense in "test postions" like these.
Way to mate isn't of any special interest obviously, just the number of moves. One could as well take any 7some position with long mating lines to see, which engine would take how long without tbs to get the right length of lines.

Solution with winning eval is to be "found" by any engine at once here too, so what?
Peter.

Cfish is best for me here too, tried it only with Forward-Backward. Xiphos has a very fine mating- search too and was second best of a few engines I tried backwarding this.
I don't see, how NNUE should help here, it simply slows down the same kind fo search, doesn't it?

As a matter of fact I don't see much sense in "test postions" like these.
Way to mate isn't of any special interest obviously, just the number of moves. One could as well take any 7some position with long mating lines to see, which engine would take how long without tbs to get the right length of lines.

Solution with winning eval is to be "found" by any engine at once here too, so what?
Why do some people enjoy Formula 1 and some like drag racing? Different strokes for different folks.
I think there is something to gain from these positions. Why, for example are they so darn difficult? Nice deep zugzwangs that keep the engines confused? Hell, on some positions, engines avoid the correct move from the get go and think for ages before finally figuring out their mistake. These type of positions are usually hailed as "good tests". Overall, all this might provide some insight on how to make the tree searches more efficient.

I agree that finding the correct move in a nice quiet position is probably closer to what engines spend most of their time doing, but gotta love tactical problems.

I think it was Has Berliner (Bob might recall...sorry if it was you, Bob) was when asked if engine evals get smart enough, then why bother to search the tree. The response was....just in case it is wrong. (paraphrasing). point is, there is always room to make things better.

Pesky FEN of the Day #2

[d]4r3/2k1p2q/pp1nR1p1/2pP1pP1/2P2P2/1P6/P1K3B1/4Q3 w - - 0 1

I was unable to locate the origin of this position, but it is either published wrong or a real pain. I had it annotated as a mate in 24 but all of the hour long searches, using many engines, only a few could get to M25. The first few moves seem easy, starting with a Rook sac. It needs more threads and RAM than I have available.

It is ECM.258 (258th position of ECM98 test suite):

I could not find if it is from a current game, a study or what.

It comes from this book:

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.
