Does playing correspondence mean I can't use analysis with the engine on?

@Rusheel_Mishra it is not allowed even in correspondence games.

@MM1993 normally, you wont be flagged. Just make sure you dont use 2 tabs at the same time. For example dont have an open tab with a correspondence game while analyzing on of your games, or having a game going, while analyzing a correspondence . Just dont use 2 tabs at the same time and you will be fine

#12 How does the system differentiate? It's cheating, though unintentional, but it is.

As i said, dont have an analysis tab open while playing a game in another tab. Or playing two games at once. If you play the same opening in two games, nothing should happen, as #14 mentioned, openings can be memorized easily.
