@Panagrellus >>#30, "And I don't consider it as an advantage at all. "

I wish (-:
I sure am not gifted at all in that compartment, I can't play blind, not even a few moves. My point is that at least in rapid games, by phisically moving pieces on a chessboard you lose in time terms all the advantage you can obtain in analysis depth and accuracy. Maybe you can examine accurately a few variants to a deep extent that you couldn't reach in your mind only, but it costs a lot of time that you could have spent thinking strategically or examining shorter variants in larger numbers. You will lose by clock eventually, and what is worst is that your imagination will never improve and you will be always dependent on a secondary chessboard. So, you think it's an advantage, but in the end it is not. My opinion.
@somethingpretentious > Imagine if you were sitting opposite your opponent in a game
I already did, I wrote about it a few posts back. That would be utterly absurd because it affects your opponent thinking. It'd be an intolerable disturbance.
> Lichess considers it cheating to play out variations on a physical board during a timed game
That's a free interpretation of this text: "We define [cheating] as using any external assistance to strengthen your knowledge and, or, calculation ability to gain an unfair advantage over your opponent. Some examples would include computer engine assistance, opening books (except for correspondence games), endgame tablebases, and asking another player for help".
You can see by the examples that "external assistance" is intended as external *knowledge* and/or *ability*. Extending that definition to include use of a physical board is a personal interpretation of the ToS text.
> It is allowed in correspondence and this is why the analysis board is provided from the correspondence game view
This I can't understand. I never played correspondence, but I wonder: through the analysis board we do have access to Lichess engine, have we? Now, *that* is explicitly prohibited by the ToS.
