I got a pm, I thought I would answer questions here. I think some people will be interested and if anyone else wants to comment that would be useful for everyone.

Just wanted to ask how it's going at NL100. How has it been so far? How many hands do you have? How's the play compared to NL50?
I only have 3k hands, and it's not going well at all. I was up 3 buy-ins after 2k hands, I've dropped 7 in the last 1k. 2 were terrible tilty calls, the other 5 I feel is mostly "variance" with a little bit of bad play.

100NL is definitely different than 50NL, although I don't think it's harder. 50NL is ...
1) much more passive post-flop, allowing me to play drawing hands
2) much less aggressive pre-flop, so I don't get pushed off of thin raises pre-flop

There are more people who float the flop at 100NL, more turn and river bluffs. 50NL is mostly straightforward play. I don't have the experience yet to tell what's what at 100NL.

Also, what made you decide to move up? Are you glad you did it? What has to happen before you start playing NL100 exclusively?
I decided to move up because I wanted to make more money. I am beating 50NL very soundly and it makes sense that I could make more $/hr at 100NL. My bankroll was right at 2k so I was properly rolled for 100NL. I am glad I tried but since it has started so poorly I need to play more 50NL and build a buffer first.

Before I'll permanently move to 100NL I need more $$. I'll probably build my roll to 2.5k then take another serious shot. I need $$ for RL (real life) so it may not be until the end of the January. If I do decently well any time soon (I played a little 100NL last night, dropped another buy-in with bad luck vs shorties ) then I would easily stay. Even a pittance of 2.5BB/100 would be sufficient for me to get by.

Obviously I'm asking you these things because I'm wondering when I should be moving up and what I should be expecting. I'm not gonna move up anytime soon, but I'm trying to decide what type of goals I should be making for myself.
GL, I'm not sure I can be much help here. I played 100NL a couple times just for fun; I had a great day at 50NL, I wanted to play but all the 50NL tables were crap, etc. I know I'm better than the 50NL players so I know it's time to move on, now I just need the BR.
