Hey guy's i am currently starting a habit of playing correspondence games.
However as this games can last for a very long time and i use the Lichess-Analysis board frequently to analyze my own games or work on my opening repetoir i am quite paranoid about accidentaly oversteping the fair play guidelines.
For example: i am currently reading Mark Essermans Book "Mayhem in the Morra" and use the Analysis board to replay the lines from the book. In one of my correspondence games however i am playing a line of a declined Morra Gambit. (1. e4 c5 2. d4 cxd4 3. c3 d5)
I think, that the resulting positions are quite different but i am still afraid of using the analysis board to study the book, while playing this game.
For me it would be very relieving to know some explicit guidelines how close the analyzed positions are allowed to be during a correspondence game, as this games can last a very long time and i can't completely renounce from doing other analyzis during this periods.
You're not going to set off cheat detection by evaluating an opening that you played in an ongoing game.
After about 10 plies when you head towards the mid-game - take care not to analyze those positions.
