1. https://github.com/official-stockfish/Stockfish/issues/4000 is not related here, this issue is about movestogo time control. 2. Your Move Overhead value of 900 is far too big. 900 means that it will take...

Not sure if it is worth to switch to C++20 but I will give it a try. First step (and not last hopefully) will be to check if all platforms...

Speed comparison of master vs. 0935b7ae19ed0282925456cb2568875910b9ffce of branch c++20 on BMI2 Intel CPU running Linux. Every version was measured three times using Stockfish perf test: `sudo perf stat -r 5...

After fixing pullLsb in bc22873a0d484a4adbe8773490abebacfb18f3ad this looks better now. Well, not for Clang. This testing is on AVX2 AMD Ryzen 3700x running Linux and using more recent comnpilers. Version|GCC-13.2 |...

ToDo: 1. Mate isn't resolved if mating line enters TB position. 1r4rk/4Nq2/7K/8/8/6R1/b5Q1/6R1 w - - 0 1 2. Improve (disable?) pruning and reductions when aspiration window sees mate.

There are several (almost all) workers at OpenBench using gcc 8 or 9 which don't understand -std=c++20 and suggest using -std=c++2a. Not working in OB is a 'no go' merging...

[s26sw_230live.log](https://github.com/Matthies/RubiChess/files/14169268/s26sw_230live.log) Logfile suggests that it is just a cosmetic problem. Rubi searching for mate, didn't finish current iteration and reports current fail low score instead of TB win score.

Let w1-b1-w2-b2-w3-b3-w4-... be the pv with SF playing move w1 and lets assume a repetition of the current position after move b3. You suggest that we should cut the first...
