Tabletop Sim’s Chess has an upside and a downside.
The upside is that as a physics sandbox, you can heavily modify the setting, introduce timers or other quality of life changes that you want.
On the other hand, as a physics sandbox the rules are only what you implement/can police yourself, the game doesn’t stop you from just moving pieces out of turn or making illegal moves, though the rewind feature can help to fix these things.
