This is a new variant I suggest you add. First you specify a time interval (say, 10 seconds), and each player has that much time to make a move. If they fail to make a move in that time, then the move goes over to their opponent, who can now make another move in a row.
Say, for example, that a game starts 1. e4 e5 2. Nf3 and black doesn't respond in 10 seconds, then white can continue and play 3. Nxe5.
