what should i be thinking on the turn? i figured i was v.likely ahead but didnt want a c/r on the turn. he could be drawing but since i have an OESD i dont mind too much about giving the free card. + i can keep the pot small if i dont improve. would b/f be better?

rivers an easy shove right? he only has $12 left

any help appreciated, thanks!

Looks good to me.
That said, since he has less than a minraise left, I minraise the river.
Even though it's the same effective bet either way, it looks less threatening imo.

if we were OOP i much rather b/f the turn but i like a check behind here for pot control. River looks standard, if he has AJ cooler.
