Two HH's here.
I'm a newbie and not very comfortable with post flop. Let me know of anything I am doing wrong or right from these 2 hands.
tbale is fairly loose, but not very much PFR's.

first hand looks good although i would bet a little more on the turn with 2 flush draws out.

second hand not crazy about the pf call but since this post is about post-flop, if you're going to raise the flop, raise a decent amount, dont minraise it.

hand 1: A bit more agression. Bump it up a bit more on the flop and bet the turn a bit harder. One of the great things about raising in position is that even one bet can threaten an opponent's entire stack, regardless of your intentions the rest of the hand. In this situation, you have the nuts, and is one of the times where you should be looking to get that entire stack in...

hand 2: just muck this garbage preflop...

On the flop, make a real raise. I like the check behind on the turn, use that position.

I totally agree with whats been said.

The thing to remember about SCs 54 and below is you will almost always have the lowest possible straight or flush. Although flush over flush and straigh over straight is rare, any serious action when you hit could mean your behind.

First hand may be wrong but you dont give him odds and at this level most don't worry about that and therefore size of bet is all they take into account.

Hand 2 agree totally with lukie, either muck straight up or raise decently to mskr him severly pay for the draw.
