Smallpot vs. nit

I'm learning to think in ranges and shit so I just want to check this. FWIW I bet with the intention of betting turn if he called.

Villain (ajrenni) was 0/0/0 over 28 hands.

Pre-flop: ($0.75, 6 players) Hero is BTN :9d: :9s:
2 folds, ajrenni raises to $2, Hero calls $2, 1 fold, Galthran calls $1.50

Flop: :3s: :3c: :ah: ($6.25, 3 players)
Galthran checks, ajrenni checks, Hero bets $4.50

Easy flop bet against opponents who aren't going to check/raise you very often (ABC TAggs who bet 99% of their good stuff for value.) Although when I'm not continuation betting, I usually bet closer to the size of the pot because I'm repping a stronger range.

Firing again on the turn might be a bit too spewy. Since we have showdown value and a couple outs to suck-out against Ax I would just shut it down and usually fold (sometimes call) a river bet.

this is fine. dont fire a second barrel though.

I like a second barrel if we had less showdown value though.
