So I was playing a small MTT on UB tonight.  My stack was about 4300 at 75/150 blinds.  I open to 333 with AK utg.  Utg + 3 makes it 1250 and it folds around to me.  I have been playing with this guy for about an hour.  I don't have HUD and don't know his exact stats but he wasn't getting too out of line and this was his FIRST 3 bet pre flop.  I HATE just flatting and having to check/fold if I miss my ace or king and I think just 4 bet shoving here is really high variance giving the fact that I think he is hardly ever light here. I am pretty much ranging him on 10's to Aces.  So I decide to just fold and save my 26ish BB stack for another spot.  Now, even though the tourney is only a small $6 buyin, some people might say just shove it.  BUT you can't be biased on the buyin level.  Should be making the correct plays on any buyin level.  I know they're very good players at there who just don't ever fold AK to single action.  What do you guys think though?
