The target is for humans who want to play in chess.com or lichess.org against other humans but to play with the same pieces that they play in games for fide rating and in conditions that are as close as possible to OTB games because it is better preperation for OTB games relative to playing in a different way.
I found the following link
https://squareoffnow.com/storeI see that there are 2 options:
1)Grand Kingdom Set
2)Square Off Pro
1 is more expensive but if I understand correctly only 2 can give you
precisely dimensioned tournament size chessboard and professional chess pieces.(I see it when I go down in the page and look at a table for Required in the last line of
Tournament size pieces & board)
The main disadvantage of 2 is that it does not have automated movements meaning
that when your opponent make a move you need to make it on the board and the board does not do it automatically
I wonder if there is a third option that give you both advantages or maybe I do not understand and option 1 allow you to use chessboard and proffesional pieces but this is only an option and you can use also different boards with smaller size.
