Started out really good, until I managed to drop 3.5k on my first stab at 600NL yesterday. Some beats, some poor play (table sheriff), can't win a flip to save my life, etc. I'm proud to say that I didn't tilt, so I kept at it, practised some better table/seat selection and eventually got back a few buyins.

Total; 39k hands, 2.7ptBB/100 spread from 200NL to 600NL, 8k profit excluding rb.
