Woot, I was anxious to play K2 after I saw the update post. Congrats to Mayhem too.

Btw, these engines work like a charm in Chessbase & Fritz 17 using InBetween and ssh to my Pi 4.

Wow so you use your pi4 as remote chess engine in Fritz 17 ? nice ! Now you can easily setup 100 games matches between the 4 cores rpi4 version of an engine against the 1 core version of the same engine in windows machine to see elo difference ^

Yup do you have a time control in mind or specific engines? I'm kind of hooked, tempted to pick up a 2nd pi maybe only 2gig ram just for chess.

Any engine, stockfish Last dev comes to mind of course to see what max elo pi4 can achieve (or another engine that makes use of 4 pi4 cores)
Taking 2 of ccrl timings (quickest and slowest).
Default Bench time for ccrl with stockfish 10 = 2054 ms (1 core)

Here is a game I just played in Fritz 17 using lc0 w/ a gtx 1650 vs K2 on the Pi4 via InBetween+ssh
15 0 TC
Considering top engine on better hardware and K2 only uses 1 core on the Pi4, it held its own pretty well.
