newb here but my thoughts would be..;
he's a big stack so hasn't much reason to blind steal so a raise preflop suggests a range of <20% or perhaps even tighter, i'm not sure i would even call preflop, what is the game SnG or MTT?
when the flop comes you have 12 outs (odds of winning 4:1) but the bet he offers you is 2:1 odds, so this would be a bad call to make, unless he has shown attempts before to steal?
Even then, he may have 2 over cards at best and you are OOP, which give him the favourite, your implied odds are high but unless you're a big stack and in position it looks better than it is.
Don't take my word for it i am new to the theory, would love to hear what others have to say
