If you mean the engine evaluations (for watched games), then: https://support.chess.com/customer/en/portal/articles/1444875-what-do-the-computer-evaluation-numbers-mean-like-2-25-
If you mean on your own games (though it also shows when watching) then the time taken for each move by each player.
Hi,
Simple question, I think. What information do the lines/numbers in the box in the right hand corner of the display during live chess games mean to convey? They change in response to each pair of moves.
Thanks.
