Piece Tracking Assistant
In RBC, the board you see does not, in general, reflect the true state of the game. Its accuracy is limited by the information you have received. You may use no assistant and move your opponent's pieces manually on the visually presented board to reflect your current hypothesis, for example, or you may play with a piece-tracking assistant which follows all possibilities.
