Hi, guys, this is suwasup

I used to fold my medium packet pair when facing 3bet and im OOP. but now i know it is +EV to call with them, and it is too tight to fold them, however, i dont understand why?

This is a classic hand. I would do the same thing if im the 3bettor. but i dont know how to react when im the caller

it is very good board for 3bettor to cbet, according to Peter Clarke, it is a unselective board for 3bettor to cbet 1/3 of the pot. and of course, with packet 8, easy call for me.

and the turn card is a Queen, he bet quite big. I know it is very likely a bluff because i would do the same. but what should i do here? if i call, and he keep betting on river, should i bluff catch, or should i raise and represent full house/set?

i face this situation so many times when i call 3bet oop with packet pair. and i just dont know how to play them, any advice?
