A few hands from my 10NL session

[RollTide77]

Hand 1: Bet more on the flop. There's a FD out there. Also, once UTG called MP was getting 4-1 on his money. Anything can happen so don't slow play.

Hand 2: Fold. Any A, K, or Q gets paired and you're beat.

Hand 3: Check this. Don't CB into multiway pots.

Hand 4: I probably would have folded PF simply b/c I'm 2nd to act next street with a low pair that will need a 4 to hit. I wouldn't feel comfortable with the odds of that happening to the odds of me losing $0.80. Again, another FD is on the board so I'm leading the flop.

Most of these you are just getting outdrawn so a little better play will help minimize the chances of that.
