Oh man.. talk about dumb.. I'm sorry man but people playing with 1500$ at the 1000 NL tables is why I made so much money when I played there with a 25k$ bankroll; you become too attached to your money, and its just too easy to go bust. I can bluff you off a hand even when you have the near nuts because your too afraid. At that level bluffing is very important and you need to able to part with your whole stack and not be afraid to move it all in the middle.

Play at the most 200 NL (youd still be underbankrolled for that, but it wouldnt be as bad). Espicially playing only 1 table, your not going to win, most people at that level are grinders that can be very patient because they play 5+ tables at once. Thats why at the high stakes the players are so ridicously tight, they never get bored because there are on so many tables (like me!). GL.
