Does representing the draw that hit, work?

Like you raise preflop and an Ace of flop.
You bet flop.
And are HU'
Turn brings a flush card that also pairs the board
Villain leads out.

Raise to represent AA boating up, Smooth call to Represent and take on Turn, or fold and stick to value betting?

In general...too

At the level you're currently playing, I'd be a lot more likely to play purely for value.

True dat. People at .25 don't care what you represent. Once you get above 100max, you can start running naked ace bluffs, etc, but at this level, ABC is the way to go.

like zach and bdc said.

however, there is a lot to be said for the flop texture on continuation bets. say you raise 5678ds in the CO and only the BB calls. i'd be much more likely to continuation bet a flop like A83 rainbow than a flop like 9TJ or 78Q with a suit.

with a flop like A83 rainbow, a villain is going to have a hard time playing with you if he doesn't already have a hand, and if he does play with you then he probably has it. with the other hands (even though they hit your hand more) there's going to be a lot of hands in the BBs range that are going to play w/ you, and you'll have way more difficult decisions later on in the hand if you over-inflate the pot. with the latter examples, i'd be more likely to wait 'til i was checked to on the turn before betting.

goodluck.

edit: i kind of misread the op. since your just playing one table, i would recommend giving a lot of attention to the way opponents play different types of hands. some check/call straight draws, but check/raise flush draws, and lead made hands. (i've found opponents that will seriously play each type of hand the a different way every single time). when you really get a feel for how villains play certain types of hands, the fun begins, and the plays like you mentioned in the op have more merit.)

I agree with above posts.

Representing doesn't work at this level.

Also milking bets on river is just loss of value. Bet hard even with nuts on river , you will be surprised how many calls you are getting everytime.
