Based on previous experience I'd say that the best method for sharing HH is absolutely to use PokerTracker.

It's fairly straightforward to go and pull out a session or two to text file and send them off.
Then the other person can import them and go through them with a replayer.

You can go to the trouble of sending seperate PT databases back and forth (e.g. http://forumserver.twoplustwo.com/sh...t=1&PHPSESSID=)
but I don't think it's necessary.

There was more in Pelion's old HH-swap thread.

A seperate file with comments is good (include a HH ID number, which is easy to look up in PT or do a "find" in a text editor).

Of course if you don't have PT it's a pain (but really, you are wanting to analyse sessions but haven't bothered to even download the trial version of PT?) and if you're on a non-PT site that could be an issue.
