Hey is anybody up for a session review?
We both send each other around 200 hand sessions that we played and review every hand of the other player and write it on notepad/evernote (any kind of note taking program).
Then we send each other the notes about the session and read what the other player has written about our session.
I think the biggest value is when both players play a similar limit. Also they should both take responsibility of reviewing the other players session and not only waiting for theirs to be reviewed.
