I prefer a real board.
Can you see the pieces better on a board or computer screen?
I have the same problem.
i see pieces better on the board, i don't know why though, i also play better when i see my opponent, it gives me more tention..
These days I'm happy either way but after a long break (17 years) from any kind of chess I started playing on line. Since I'd read my share of chess books the 2D view wasn't a problem.
After a few years of Internet chess I joined a club. I certainly made some blunders at first due to the no-longer-familiar view of the board but it didn't take too long to get used to it again.
But I made a classic on-line/OTB blunder on my second night. I pushed a pawn to the eighth rank. I can't say I queened it; I didn't. I just sat there waiting for a prompt before clicking on the Q.
After a bit my opponent replaced it with a queen and I realised what I'd done.
Believe it or not as you like, but it really happened.
I felt like an idiot!
On certain occasions (playing online), when I’m in a dilemma of “what do I do next,” I make the best of both worlds by using the board & pieces, instead of staring endlessly into the glare of my CRT.
