There exist statistics for distance to mate, but I don't think it exists for distance to promotion. You should be careful there anyway: not all promotions are winning. You should calculate until the first move with the promoted piece. It think it is sufficient to check that the promoted piece canno...

is -45Elo for Minic ...

Does this happened to someone else ?
Any countermeasure (apart from falling back to gcc9)?

Add - O3 to the compiler flags. (Hopefully this is a stupid suggestion.)

There is no any new announcement there.

Some people are interested in technical details. You are not one of them, but I am not writing for you alone.

Now it search only to 13 plies depth, not enough. Whole bench takes 2,5 seconds. Better change either depth to about 18 or movetime to about 500ms and You get automatically usable result!

Usable how?

Did you try LazySMP? Easy as falling off of a log and seems to work really well. It's insane that seemingly small tweaks to what was considered the worst-scaling algorithm (shared hash table) somehow produces the best one. I don't think the small tweaks made the difference. In the old days testing ...

Not long ago, it was believed by many, myself included, that making use of Hyperthreads for engine play was sub-optimal. At one point Fishtest's wikis contained guidance to Users to not use Hyper-threads. Similarly, Houdini once came with such a disclaimer. The use of hyperthreads for fishtest is a...

Because SF prefers 0.00 over -0.01.

With the standard contempt of 24, that would be preferring 0.00 over -0.25, no?

It would be preferring -0.24 over -0.25. If a draw is evaluated as -0.24, then moves leading to a -0.23 evaluation would be preferred over moves leading to a draw.

If you think that some move should be different then you should give a position and say what move stockfish played and what it should play based on your opinion. I am just asking those who know how engines are coded why a top engine like stockfish "accepts" to get into a position where the opponent...

If SF always search for opponent's possible checks to its king's in say next n moves we can then assume that when a 3 repetition by forced checks occurs SF is never taken by surprise then ? Yes. Stockfish knows that this will be draw through repetition. In particular, checks are extended in search ...
