The Chess beta site now has a cool replayer, to allow Chess games/positions to be described, rendered and walked through. It's been around for a couple of months now.
We've been asking for this for some time. We already have a nice go renderer, and basic card-linking functionality for magic-the-gathering, both of which have been great. Now that something has been written for chess, our 6th most popular game, could we please have the same functionality enabled here?
