Tough to fold with this price. Villain might just go with his 2pair hand here, because he will be pot comitting himself anyways.

he should raise 2pairs OTF often..

I would bf OTT :) specially since he plays short stack then probably he is a recreational player -> in general a lot more flush combos here

Against this type of player, i think : Bet/fold > bet/call>c/c>c/f

commited with this size on turn ... when we bet we call.. wp imo vs 18.70$ stack guy.

If we gonna bet fold .. betting like 4.50$ max on turn is better

I think it's pretty safe to assume that villain has a flush here. I would fold.

dont you guys think that recration player might call some sets/2pair OTF, and OTT he's scared and just shoving it?

Your range is very strong here when you lead into 3 people. Also you gonna have a ton of flushdraws since you got such an amazing price on your complete in BB. So on the turn you will have alot of flushes in this scenario and if the CO understands this I think he will almost never bluff you here and shipping a set would just be bad.

Also I think if you bet you can make big mistakes and get it in really bad.

If you check he is more likely to make mistakes.

I think if you check he is gonna play his hand somewhat faceup. If it goes c/c you can valuebet the river. If he bets twice you can fold the river.
