Neither do I.
They always know the moves you should have played, the moves your opponent could have played, and they're never shy about sharing all of that.
There is a world of difference between kibitzing and annotating, despite their allegedly similar goals.
I mention all this because after Welton Vaz ("Gandybh" at Chess.com) completed his Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) treatment of the Semi-Italian Opening (1.e4 e5 2.Nf3 Nc6 3.Bc4 h6) (see "Italian Game Anti-Fried Liver Defense Part 1"), he submitted it for analysis to the computer at Chess.com.
The result was surely educational, but it was also relentless. I chuckled my way through the game – it was a fun, exciting, typical Semi-Italian Jerome Gambit – because of the computer's notes. A computerized kibitzer – what will they think of next?

(I prefer to play something like 4.0-0 and wait for 4...Bc5 before sacrificing my Bishop, but Gandybh is a braver man than I am. Still, we have seen 4.Bxf7+ on this blog before: perrypawnpusher - marapr, blitz FICS, 2007 and Fuller - Vallance-Gallant, Women's Open Championship of Canada ICCF, 2008 – Rick)

The computer's comments remind me of something a friend would say whenever we finished a chess game: "I was winning, you know" and I would reply "Yes, you were winning – right up to the point where you had to resign."
