So far I was just sitting in at a new tables and playing with whoever joins.
I am also going to start using SpadeEye for a better table selection. I've already started datamining games, since my Bankroll Management is a bit too aggressive and I want to make sure I start grinding the weakest available games.
Hopefully, it won't take me more then 10 days to reach NL 50. The last two days weren't too great, but I still made some progress.
