Stockfish ? Leorik 2.4 is already a much too strong opponent...In the sample below, Relaxchess9.8 plays on 4CPUs (by default it uses the full power of the PC). The match took place on Arena 3.5.1 GUI. QRelaxChess GUI is quite interesting !

movetime 1 second, Stockfish default settings (level 20), and QRelaxChess playing BLACK this time. Not only winning but much faster than Stockfish!.
QRelaxChess uses processor power and not your memory. RelaxChess engine is unique not a copy as the most, and is very fast in standard mode.

One remark : the games are played on Ubuntu 22.10 not on Windows.

[Richard1964]

I have played a match against RelaxChess10 and Stockfish 15.1 engine (50 games).
Environment
1) QRelaxChess game
2) OS Ubuntu 22.10
3) Stockfish default settings (Skill Level 20, max.), RelaxChess advanced mode
3) movetime 1 second, it is embeded if RelaxChess engine plays in advanced mode.

Result
relaxchess (white) / stockfish (black) : 12 : 13
relaxchess (black) / stockfish (white) : 13 : 12
Total score 25:25

This is only playing fast chess, with longer movetime settings, stockfish wins at this moment.
