It would be really great if it was possible to link to a specific point in a game. That is, give a url to a game, but with the url including a move number or a variation point.
A simple use-case is being able to make reviews in Reviews requests - Online Go Forum without including a gazillion screenshots in every post. In my last post in that subforum I included 13 screenshots of the game I was reviewing.
In another review thread I included 28 screenshots in my review, and had to split my review over two posts because the forum wouldn’t let me upload that many screenshots in a single post.
Screenshots are a wasteful way to show a position. I’d rather include a text diagram or a link to the game.
Yes, I only added support for move number from the game main line. It would be a nice enhancement to add support for variations, I’d imagine a url structure something like gameid/45/v/1/5/v/2/7/v/2 which means at move at 45 take variation 1 then on move 5 of that variation take variation 2 etc. But that might be a pain to add to the allowed url structure so maybe as a query parameter. To make this usable the link to game dialog would need to generate it for you, which isn’t so necessary for just one move but would be nice to help people discover this feature.
