I think I could have gotten alot more value?

$0.9 on flop
$2.1 on turn (into $2.5)
jam river

edit: that seems close to pot on river. if you dont' want an SPR of ~1 on the river you could probably overbet the turn because his calling range will be a lot of pair+draw or two pair hands which won't fold and it sets up an easier river shove. i'd just do the $0.9, $2.1, jam though
