I moved up to the $200 buyin table on PartyPoker last week. I played three sessions. Up $250, down $400, down $650. Now, that is only a loss of 4 buy ins, which is not really that big of a loss. Losing 4 buyins in NL is not that big of a deal, but I was not ready for that big of a loss to my bankroll. I do not think I moved up prematurely, I still believe I can beat the $200 buyin, however, I think it is in my best interest to move back down where I am comfortable playing at.
I think this is one of the main reasons I have been successful in online poker. I do not take too many risks. I played the $25 buyin for nearly a year before I moved up! I learned so much in that years time. I stayed at the $50 buyin very briefly before finding a sweet spot at the $100 buyin. I still think I need more time at the $100 buyin to build my confidence before moving into the $200 buyin.
I was just not mentally ready to lose $800 in a span of a week in about 10 poker playing hours. When I am ready, I will move up. Until then, you can find me at the $100 buyin table on PartyPoker.com
