Yasser Seirawan provides engine-free commentary on many of the top events. It is rare that you can follow his commentary free, but the dollar or two that each game costs is well worth the price. Even he, however, will mention engine analysis that his viewers feed him through comments.
Seirawan is not the only one. There is plenty of master commentary available. But, engines are cheap and usually reliable for sorting through the tactics. Engines are not always correct, however, and as you point out, engine users ofetn misunderstand the difference between even and drawn.
In game 7 of Anand-Kramnik, WCC 2008 the engines could see a clear advantage for Anand, but even I (a B Class player at the time) knew the engines were wrong. See my blog for "live" commentary produced during the game.
So I've been watching the "NH Chess 2010 Rising Stars Tournament". Before that, the "Ulaanbaatar Tournament". The internet is soooo wonderful for allowing us to watch the Grandmasters, IMs, CMs, and NMs play chess, live, without having to be there, or wait until next month or so to review the games in some chess magazine.
But the bloody comments from peeps watching the games online, are usually very annoying. These people just look at what 'Stockfish' evaluates, or their own engines they're running, and comment "Draw", if the engine has the position roughly even. Or, they just start criticizing the player whose position is evaluated dubious, by their engine. I don't know much about chess or birds, but I know when a parrot is watching a game and uses his/her engine to make comments on positions they know nothing about. They just mimmick the engines evaluation as if Hou Yifan and Konera Humpy for instance, are machines. "Looks like a draw", has got to be the most annoying, and empty comment of all. Move 21, and it looks like a draw to 75% of the people who comment! Ridiculous.
But I do have a question in all this. It is probably for those with more experience following chess than myself.
Do you think the chess engine is reducing Master commentary on chess games in progress? I know there must have been a time when chess master's commentary during a master game of chess, made it more exciting with the suprise factor. But with the reliability on the chess engine, the suprise factor, the brilliant combination, the unpredictable, doesn't seem to be there when some 1100 can sit there and say, "Giri just blundered horribly! What was he thinking?"
