It seems that version 20 is very good. I play live on PlayChess with only one core (!) and only 2200 kns (hard-test) in the starting position. Still unbeaten after 63 games. Settings: MCTS = single, learning OFF, the rest standard. I will publish all the games later after the test (minimum 100 games).

Engine has to play a lot of difficult openings, like C65 with black and white, and closed English variants. The engine also had to play Caro-Kann, French and Kings Indian. And all against opponents with up to 64 cores!! With a core against 64! It's incredible how well ShashChess plays.

Looks live "Live Book" feature doesn't work for ShashChess. It works for BrainLearn strangely. Also feels like experience file doesn't work too.
If you have one can you upload it ? My experience file might be outdated. Thanks.

Livebook is exactly the same as BrainLearn.
Theb Learning hasn't changed since 20.1 and it worked.
I don't have a free big experience bin file.
Sorry.

Sorry my bad looks like "Live Book Timeout" value was too small.

ShashChess has the peculiarity to be very good in study solving AND to be very close to the top in playing strength.
It's he only engine I know that can do that !

ShashChess 20.2 - Powerful and strong!

After 140 games with setting MCTS 1Thread + Tal, on PlayChess currently +9 =131 -0. That is very good (TOP) on Ryzen 3900X (22 Threads), with my Shortbook "Black&White.ctg" only.

[Black "SolistaChess, ShashChess 20.2"]
[Result "0-1"]
[ECO "C54"]
[WhiteElo "2737"]
[BlackElo "2741"]
[Annotator "?ev?;0.03"]
[PlyCount "222"]
