Re: On-line engine blitz tourney March

LczTinker with LC0 on a 2080ti took first place, ArasanX did very well and ended above Belfish (a Stockfish derivative). Belfish and rofChade ended both on third place. This time there were a few problems: atomBaron didn't want to move so Lisebeth had to forfeit it, she also removed Bliep to keep th...

Re: On-line engine blitz tourney March

Re: msleep

If you want to have sub microsecond accuracy on Windows you can use QueryPerformanceFrequency() and QueryPerformanceCounter().
