The thing is, I've played long enough (card rooms, etc) to know that I'll make mistakes if I play in long sessions. So I try to compensate by using a "hit and run" strategy. Short term luck vs long sessions.

And sometimes I leave because I just don't to get stuck playing 10+ hour sessions, which I have known to do before.

If I win 95% of my session, that must be a good thing, rather than quiting because of a losing session, right?
