so it's a large field MTT in which you need a ton of chips in to make the final table right?
Since this is a freeroll(it's a freeroll right?) i would persoanlly just dump the chips in the middle preflop. Which might seem reckless but i really don't like to jsut call preflop and let him bet on the flop and take us off our hand. So i would just 4bet jam and go with it. However if the tournament means so much to you, then i think folding is probably going to be better than just calling here with our stack size, since he is likely 3betting with a decent range but not super tight means he might be 3betting with worse Ax pairs broadways, not sure about how wide typical
freerolls are, he might also call alot of those
hands. But he will have similar cards to us meaning we hit the flop a little less often, and we only hit a pair 1/3 of the time meaning 2/3 of the time we have hit nothing. Now since we're suited it adds a little more value to the hand since we can flop really good flush draws, but overall we're going to be flopping nothing the majority of the time and he has position, making our hand really hard to play if we miss.
So as played i would jsut fold the flop, but i would almost always just shove this in over his 3bet considering he will likely get it in with worse since this is early in a freeroll and we cannot be busted out of the tournament and we will be left with a decent chip stack if we call and lose. But if it means a ton to you, then i would think folding is a better option than calling to a flop, but i also think 4bet shoving is by far, the best play availiable here.
