It's only the third hand I've seen at this table. I don't know raiser.

I didn't like his call on flop. I guess I bet the turn hoping guy would fold thinking I had flush.

Do you call on river? What do you do with an overpair out of position vs unknown raiser?

Comments/corrections appreciated.

id check fold the turn cuz his pattern looks A LOT like a flush.

if he had a big hand like 2 pr, a straight, or a set ... dont you think he would 3bet the flop so u dont draw to a flush?

also his initial flop bet is so small that that leads me to also believe he has a flush draw ...

this guy obviously isnt afraid of the flush and is in fact welcoming that turn card.

I raise pf, or limp reraise if I limped in.

On the flop I probably go ahead and lead. He'll have to like his hand to stay here.

One the turn I'm done with the hand.
