From the start of video it looks to me like the King is on H8, so from with this position and couple second analysis in engine I do get Nxh6 as best move.
Of course ! That's where I was wrong.

Re: Minic version 2

That's 2 different things here. 1°) To use a syzygyPath with pre-build Minic, just use the command line (this is not a GUI option yet) minic -uci -syzygyPath /your/path/to/syzygy/ 2°)To compile Minic by yourself (I don't recommend this for testing, only if you want to develop in it), you will need t...

Re: Minic version 2

If you put Fathom directory inside Minic then from Minic root directory g++ -IFathom/src -ISource Source/*.cpp -lpthread (and whatever other options you want) Shall be good.

Minic version 2

Minic is now too far from one of its original ambition, being a small code size. With around 5000 lines today, it is maybe time to make Minic less ugly and go for a better multi files repository. This shall take some time, but I think i'm gonna go this way, splitting Minic in some files and comment...

Re: Minic raw speed

Back on the same subject ... In fact Minic has less cache misses and less branch prediction misses than stockfish ... Perft 6 of start pos in 4.7sec, so move gen + copy make at 25Mnps .... probably not the issue It depends on the speed of your CPU. Perft 6 from the starting position runs at 4.4 sec...
