Seat 5 = MP2??

I'm ok with your line, I'll do that sometimes, I more often play faster 5 handed on the flop in a tournament here (go for the C/R if table dynamics are right, cap it), especially in a horseament, but other times I even fold, it's a very read based.
Don't just assume you're up against KK in an MTT, and don't ignore the other two cards in your hand which give you a nut gut shot and act as a blocker to wraps.
