If you like chess this game is quite good and allows use of 2d picture pieces on board, 3d 'standard' pieces or 3d animated battle pieces.
I was asked to install a wine file. This 'froze' the Steam Deck. After a restart I ran Steam app from desktop and installed the file. Went back to Steam [out of desktop] and all worked fine.
The game has a square / piece selector - circle - that you move around. The game board rotates and this can mean the selector moves on diagonals only. Simple fix is to rotate the game board for alignment.
The game works really well on Steam deck but the controls take a little while to get used to.
Had to use Steam Linux Runtime (but still means native Linux of course) otherwise the game wouldn't start.
Utilisation de Proton 5.13-3
The native version of the game would not launch, however the game launched fine on the latest official version of Proton (5.0-8). Only had to set this launch option "PROTON_USE_WINED3D11=1 %command%" to get the game to run.
Works
Works out of the box using proton version 5.0-5.
