I'm a new blogger and could use a little help from experienced bloggers with Blogging 101.  I've posted a couple of games with a ton of variations and analysis, but I suspect nobody will bother to look because it's all buried in the move list.

I've noticed that experienced posters can take a single game and break it up into sections so that the first 10 moves or so are in one diagram, the next 10 in another, etc.  WIM Engergia does this all the time in her excellent endgame articles.

Could somebody tell me the secret to doing this without having to repost the entire game each time?  I'm sure it's obvious once you know 

If any Good Samaratians have time to look at my first two blogs and suggest other formatting improvements, I'd be grateful!

Thanks!  E.P.

For example, if you want to show only the middle section of a game, there doesn't seem to be an easy way to do that.  If you import the pgn for the game, then the game starts on move 1 - not in the middle.  If you begin instead by recreating the middle-game position by hand, then there doesn't seem to be a way to import the pgn only for the moves for that section -- instead I find myself putting all the moves in by hand.

Obviously, I don't know what I'm doing here.   Somebody reading this is surely thinking "doesn't he know that he can simply...."  I'd really appreciate hearing from that person.
