What Renton said:

Tighten up a little and limp less from EP/MP
Raise more from LP (i still battle with this one)
45% is too loose from the small blind. Playing poor hands OOP sucks.
10k is not enough to have much idea of your win rate.

Take that for what it's worth though... I run at 14/7 these day's and I've always been a tight player. I've seen players at 25NL with really weird preflop stats, but who still seem to be winners in the game. As Bill said, it's a postflop game.

Where did u play these hands. Party?
