Pragma Chess points out what can help, when it can help: a balloon on the control, the first time. It appears once per run at most, and Don't show this again in the balloon puts it away for good.

• Explain is pointed out after a move you make on the board that looks like a trial: one the engine judges an error — with the analysis on, or when it already knows both positions — or one off the moves the Opening Tree offers, out of the openings the book knows. Not in training, which has its tutor, nor while playing online, nor while Explain is already on.
