Table has been kinda passive preflop. I have been a bit LAG I think (at least compared to my usual style), taking away lots of pots post flop. No real read on the villain.

Preflop: Hero is UTG with 9, A. SB posts a blind of $0.10.
Hero calls $0.25, 5 folds, Button calls $0.25, 1 fold, BB checks.

Flop: ($0.85) 7, T, 5 (3 players)
BB checks, Hero bets $0.5, Button calls $0.50, BB folds. <-- tried to semi bluff it, putting him on either a lower flush draw or AT/similar.

Turn: ($1.85) 6 (2 players)
Hero bets $0.9, Button calls $0.90. <-- hit my flush, decided to lead half pot to set up a larger bet on the river. Putting him on either a made flush or a (imho badly played) set.
River: ($3.65) 9 (2 players)
Hero bets $2.5, Button raises to $5, Hero?? <-- ok, he minraises me after I've lead out on all streets. He's got something he likes, it's payday. But how much to bet to extract most value?
