Guess what?They will say the board is a "reference" tool and a new round of endless "discussion" will start.
Recalling games (in your mind) played in the past is also a reference tool. Recalling how to move your knight is also a reference tool. According to this logic everyone is cheating.

I only read page one.
I think the rules must be changed, if you are not allowed to testmove on a board when playing livechess.
Because it is not possible to control, and all should have equal rights to tools.
I would never use such board, because my goal is to improve otb, for that reason I need to train my brain to visualize without bordmovingassitance.
