Getting bet off top pair too much

[sean c]

Why did you check the flop in hand one? Were you sure the CO would bet if checked to and you planned on check/raising?
I would have bet.

In hand two i would have raised pre flop and as played i would have 3-bet the flop you have top pair and two nice backdoor draws. I think this is to much of a hand to be folding and cold calling may encourage people behind you to join in.
