Well honestly it could be anything if it's a fish. People do some really stupid shit. But do you realize the read you have to have to fold this? Your read has to be so strong to even consider a fold, and it has to be over a large enough sample to know that the read even means something. That kind of read is impossible in a small stakes MTT. You can't fold. It's just absurd to fold.

Don't get me wrong, I'm a little sad when the guy raises NAI. Not because I know he has AA, but because his raise narrows his range and yup AA is still in it. But that doesn't mean we can fold KK preflop with 15bb after 3-betting.

You said "late stage" in tourney. If we're talking a final table ICM spot with stack sizes and payouts that matter, then I'm willing to listen. But this wasn't that.
