I am not sure what to write about Bryght Labs - I can write about ChessUp. Very good board. I like that fields are brightly lighted when moves are evaluated. I like that it is possible to control board without phone as well. That is a very very good advantage against other boards - which is strange why others have not thought about it. Perhaps there could be next stage of development when the lighted fields can send some info, I.e., when board for some reason got messed up (that happens when accidentally few pieces are moved and not placed back when played against ai - then board loses control what is going on and stalls). For example the board is messed up but you want to recover the game to continue from last location - then fields could show what to place where - say fields would have small symbols of knights, pawns etc so that one could place fields to location accordingly and restart. You probably could do it if you use app - but beauty would be to avoid phone altogether.
