Hey guys, FAQ on LHE part of forum says :

What kind of bankroll do I need to play X limit?
If you play recreationally and are willing to move down if you hit a bad patch, you should have 300-500 big bets. If you are playing for a living, you should have at least 800-1000 big bets plus six months living expenses.

I have some NL experience, but am a newbie to LHE. If I want to be on a very conservative and secure bankroll management, is 1000 BB enough ?

Thanks
