Rock My Chess World

This site is fragging amazing! Yes, I'm a chess nerd, and perhaps I'm easily impressed, but that doesn't make chessgames.com any less noteworthy. First of all, they have an online, searchable database of about a third of a million games, dating back to the 1800's. Second, the database is searchable by ECO code (among other things). If you know, for example, you're playing the Four Pawn Attack against the King's Indian Defense, you can find its ECO code, E76, and then search for all the other games that opened the same way. Nifty
The part that is irrationally cool is the Chess Opening Explorer. Once you've looked up an ECO code on the main site, you can launch the Chess Opening Explorer for that opening. You then click through the follow-up moves, with each step showing you win/draw/loss statistics from their database for that continuation. Go try it!
Perhaps this technology is nothing new. It sounds like Fritz may do something similar, but just getting started playing research-augmented chess, this site blew me away.
