This is my first hand of the tournament as I entered late.
Villain calls flop and turn bets quickly but pauses for about 10sec before betting river. Without any reads is this always a fold? or does villain bluff missed draws/ value bet worse often enough to call? Most people will give up bottom pair to the turn bet so I shouldn't be concerned with him showing up with trip 7s? More likely his value range is straights and full house right?
