Here is the situation. I have a friend with whom I very much like to discuss chess (our games, other games etc.). We are not living in the same country, so we discuss chess on-line. During our on-line discussions, we often, of course, need a chessboard. Usually, we use our wooden chessboards (which we see through our computer cameras), but this is inconvenient, as it causes synchronization difficulties.
My question is: Is there a site or a chess program with a chessboard which both my distant friend and me could see and alter, in such a way that every change in position is simultaneously shown to him and to me. In other words, something like a "live analysis board". If we were at the same place, we would have a chessboard on which we would analyze a game. He could alter the position, and I would see it, and vice versa. Now, I need the same thing, just on-line. Does anybody use something similar and/or has a suggestion?
I hope my description above is enough to understand what I mean. Obviously, my English is far from perfect, but I hope it will do.
Finally, I would like to stress that I am NOT asking for a suggestion for a site for PLAYING chess, but for ANALYZING games and discussing different positions.
Any suggestion would be appreciated. Thanks!
