if only the jump from 600 NL to 1000 NL was as easy as the jump from 50 to 100. When you get up to 1000 NL you start getting this pressure, i dont know how to describe it other than you realize how much money your "playing" with and if your not careful it can really get to you. 1000 NL is intense no other way to describe it. And I played 600 for a long time.
