Although open-air chess boards with large pieces have been mapped as leisure=pitch, as have outdoor table tennis tables, I think these are allowable exceptions: further extension to things such as this will result in every consumer of leisure=pitch needing to check the sports tag to see if it is something which might be described as a pitch. I think such extension of the semantics of a widely used tag to map a small number of things is poor practice.

Far better to develop a separate tag for things like this (including perhaps table-tennis tables). Board games are usually described as a pastime or hobby rather than a sport too. In fact there are already 11 instances of leisure=board_game: I haven’t checked what they refer to (there are also 36 amenity=cafe + cafe=board_game for board game cafes, and there may be some overlap). You could certainly use this tag, although something slightly broader may enable other cases to be handled too (off the top of my head, something like: leisure=pastime, pastime=board_game, board_game=*).
