If you go a long time without playing on a 3d board, and do a lot of work on 2d board, then I think it can affect your play until you get used to it again. It may only take a few days to get used to it again... or maybe a month... just depending on how experienced you are and how long your break was from 3d.
I also speculate that the stronger the player is, the less the switch would affect them... because calculation is done in the head anyway, and the board becomes more of an intermittent reference point.
Is playing 2D chess ( like playing chess online, solve tactics puzzles on a book ) affects our play on real board--3D ( probably tournament )???
cause i THINK i tend to have a better visualization ( easier to spot tactics ) when i play 2D chess, cause the whole board is flat, all the pieces,weak squares are clearly shown....
so DOES playing 2D chess for a long time affect our tournament play?? should i have to place a REAL BOARD infront me so that i can follow and think the move on a real board when playing live chess in chess.com??
