user1758: Is there an online analysis engine that allows you to enter a PGN and get a game analysis, showing where suboptimal moves were made?
I know there are programs for download/purchase that do this, but I specifically want an online one. The ones I've found (e.g.) can analyze positions, but not entire games.

user15365: I recently found that chess.com also has a free option to analyze an entire game (by pasting a PGN), although paid accounts can analyze in more detail.

The analysis process will intercalate comments idicating better moves if necessary. In the end, you will see a summary like this:
Strength        White   Black
-----------------------------
Excellent          41   38
Good               13   13
Inaccuracy (?!)     1    5
Mistake (?)         2    0
Blunder (??)        0    0
Forced              0    0
Best Move       66.7%    50.9%
Avg. Diff        0.14    0.19

Its analysis shows wrong and right moves and percentage statistics of mistakes for both sides.
