What is better: 2d computer chess or 3d (like an actual board and pieces)?
A48: Many pros don’t use the real chess boards at all (even Carlsen once said he doesn’t). The times when you had to take a chess set with you during travels are long gone. However, at training sessions it’s very convenient and useful to employ a real board. It helps you feel the position much better and memorize the main ideas by playing them out with your hands. Moving pieces on the computer screen is convenient and fast, but less efficient in terms of memorization. Therefore, I usually use both a computer and a chess board.
