I hope I'm not the only player who has cringed reading some of these "shortrun" and "shortminded" posts. I don't mean to say that in a negative, condescneding way, but only as definitive.

Rule #1 (based on soupie's lessons)
Exercise bankroll management.

EXERCISE BANKROLL MANAGEMENT.

You do not risk more than 10% in ring or SNG, or 5% in MTT on a daily basis.

Iwind. With 1k, you can be playing 4 25nl tables at most or 2 50nl tables at most. Anything more than that and you are putting yourself in danger in the longrun. Sure in the shortrun you may have a great day at 50 or 100nl but variance (esp in NL) will catch up and catch up quickly. There aren't any exceptions and if you want to endure over the longrun as a player you won't practice anything else like prematurely move up in stakes like other players here have. You'll notice that most of them have either played for a very short time or have even come out and said "I'm not a very good player."

However, the previous paragraph was more directed for the other players who have advised that its not so bad, etc. Moving up in stakes is simply a level of comfortability that depends upon your preference. The one thing I would like to refute is looking at each stake as matter of $100 loss in a hand or $50 loss in a hand. I don't think you should be placing monetarial views on moving up in stakes. Its simply a matter of how many buyins can i lose before I violate BR management and how many buyins I can risk at one time. The ability to disassociate yourself from money values and focus on BR and buyin values will make you a better player and probably less effected by losing hands. Let's face it, losing $25 and losing $1000 should have the same effect on a player from 25nl and 1000nl. You lost a buyin. Any different reaction and you're not comfortable where you're playing and you're either viewing the loss from a different perspective (and I would argue incorrect perspective) or you're not managing your bankroll properly.

Ignore the quick money players who play multiple 100nl tables with a 1k BR because "it's not much harder than 25nl." I guarantee you that if nothing in their play or BR management changes, they will not be posting here 6 months from now. It's a statistical fact that variance will kick in and there will be huge downswings. A 100nl player with a 1k BR will be gone faster than the time it took to read my post.

The bottom line is that you sound like a solid player with a solid foundation who is starting to prepare himself for the "what's next" step. Stick to what has done you well so far, stay within your means, and you'll be here a year from now.
