UTG 25/18/7 over 320 hands
On the river we gotta call 55.

OTT I will raise sometimes, decided not to this time.

So on the river I was thinking about a couple of things. When he checks after repping pretty strong with his sizings either I don't really expect him to be strong(sets,straight), or he's planning to ch/raise me(flush, or some blocker), which I'm not sure about, since I will check back a lot of things that might pay his 3rd barrell off.
The other thing is my sizing. It's hard for me to find too many bluffs so I dont wanna make it big probably.
Any thoughts?
