As some have discovered, a new tool has recently been released to help annotate games played on the site. It is not a requirement that the game be your own – you are free to annotate any game.
When viewing a board from the "game history" page you can use the "Annotations for this game" link to view any annotations that may exist for a game.
You may review other’s published annotations for that game, or you create a new one. Your own annotated games can remain private, or be published to share with the community, who then may add further comments to each of your annotations when using the “flat view”.
PGNs can be copied and pasted from the interactive viewer and inserted into the forums using the normal [ pgn ][ /pgn ] tags or a link to a published annotated game can be achieved by using [ annotationid ] [/ annotationid ]
If you would just like to see all current published annotated games, use the "Annotated games" option from the "community" menu.
edit : examples added.
Thanks Toe Tagger Joe, I used your annotated game for the examples.
