I found the realtime cga analysis board really impressive from a 1982 perspective. One might say "pfft..." to it today, but back in the day, that would have been some really flash tech.
More than that, actually getting a glimpse of the GM's faces in real time is very rewarding. There are a multitude of entertaining analysis videos of chess games on Youtube in which they show the moves and the important variations, often with inciteful commentay. But it can't quite compare to watching film of a real-life dude actually lighting a smoke, scratching his bum, belching, then reaching foward to play e4.
The real-time element was fantastic as well. In reading through the moves of a famous game, you generally get absolutely no idea about - let's say - move 24: black is getting into serious time trouble. The temporarial (if that's not a real word, I've just coined it) aspect of the game is usually lacking in most game analyses - unless it's only to say "move 67 white loses on time." Getting a genuine insight into to the length of time top-notch players spend between moves was enlightening.
I'll be the first to say that at 1600 (a grade which I've gained primararily through getting a kick out of pantsing 1300s) I'm really in no position to judge the quality of analysis of any chess game. But I must say I found the dialogue a little dull and/or indecipherable in the vids. I'm not saying I could do better, but I know I could be more entertaining. And hell, entertaining is what it's all about, for a rank amateur like myself. I play chess to have fun, nothing more, nothing less. A bit of escapism. I love it. Now, the commentators in these vids sound like they're debating an alimony agreement. C'mon dude, you're getting paid to do commentary to two of the greatest minds in the world in a sport that you love. Either sound like you're enjoying it or piss off.
Commentary rant aside, I'll reiterate that I loved the vids. Two guys played a game. I saw them at it, it was great. More please. I understand that occurences of television coverage of chess are few and far between but I'll be keen for anything you can link my way.
