I'm getting more serious about playing online for money, so I have some questions...

I'm six-tabling (10-max) $2/$4 on PP. PT has me as a UA, but I want to know how I can improve my game even more. Should I examine my hands that are losers for me and consider not playing them as much even though I know that overall it's +EV to play them? I've really restricted what hands I play. I typically won't play QJo, KJo, or A-rag suited in early or middle positions, and I tend to dump most PP if I'm not in a late position. I feel like sometimes I miss a bet on the river here and there.

Here are some of my stats over 3073 hands. I'd appreciate feedback. If requested I can post other stats. There are so many and for some reason PT doesn't like to print to PDF.
