Keeping track of too many hands (let alone stats etc') is hard, not effective and will prevent you from playing the next hand well. So yes, just take note of hands that you think are interesting, on your phone, using text editor of your preference. Most of the hands are standard so it's really about 2-3 "interesting" hands every 10 hours or so. Then after you look at those 2-3 hands "offline" after the session you will find out that some of those hands are in fact standard as well. Then post the remaining hand on 2p2. During run bad times, more hands will appear "interesting" than during "run good" period because during "run bad" period you will seek more "reassurance" from your poker buddies / authorities that you keep making right decisions. That's ok I think because it happens to me all the time
P.S. all hands that I posted so far where I took a bad / fishy line were a fruit of my imagination. They never happened. I didn't know that GM and OTR have a similar syndrom
