To follow-up on Dylan’s post about Comet games in more detail, the folks at chess.com have launched live.chess.com running on the Jetty implementation of Cometd with the Dojo client and an ext.js UI. This site does exactly what it says on the tin! This has only been available for a few days, yet already you will typically find several hundred players online watching or participating in 50 to 100 games. Most of the games are run under tight time limits, so the action comes fast and furious (Ok, it’s not world of warcraft, but fast and furious for chess!). The user interface allows you to watch/participate in multiple games at once and to customize the appearance of the the boards and pieces.
