Sailing with ease through NL2, but crushed in NL5?
I'm playing zoom on stars, and on my last 70k hands I've steadily won at a rate of 10 bb/100 on NL2.
Now that my bankroll got to 200$, I decided to try some nl5. Played pretty much the same way, but didn't go at all as I planned. I only played 4-500 hands, but went down 12$. Reviewed some hands where i lost 100bbs+ one was just a cooler, and the other was when villain calls down Q high board (i had AQ) just to hit a jack on the river (had QJ).
I decided to stop after that hand, and now I ask you people at cardschat. Do I really need to improve my game for NL5? And, if there are any, what are the major differences to Nl2?
