Since phpChess is also pure html output (ie no java, java script)
1) I was wondering if you solved the drag, drop restriction in html?
2) Also are you offering real-time games? phpChess does, but with a workaround (we send the move time in an envelope, so the server can make sure no-one losses time, but it has some side effects (like your time can run out, and then you get two secounds back.
Nice look and feel
kind regards
