NL50 up and down

Played the last weeks very successful on NL20. So i decided to go one level up and started to play with the big stack strategy on NL50. Unfortuantely, my downswing started at the same time or i am really to bad for this level right now. Lost nearly one third of my bankroll with top full house against quads and all such bad things. So i started with NL20 again and since today i am back to a bankroll of $520 at mansin poker. So i will give it a new try ;)
