FT 25NL 6max - Two Pair in the BB - Bet Sizing

[shoxbb6]

Villain is 30/19/1 over 150ish hands, most of them datamined.
Hero got his stack before villain sat down, and hasn't played any decent sized pots.
Villain got his stack when he called pre-flop with a suited connector, called a psb on flop with a gutshot in position, called another psb on turn after improving to an oesd, then shoved river after hitting the straight.

flop bet is a little large, not terrible though

bit more on turn and more on river, are you really worried villain is still in ther with a 5? I'd only be worried if he was very passive (calling down with 85/J5)

[Tickner]

Bet $5 on the turn, and $12 on the river.

As played, bet $10 on the river.
