Cold min 4-bet from the blinds

[Alpine021]

Early in the tournament so no reads.

I didnt know what to do here. My 3 bet was only a small one as I was IP.

But the BBs min 4 bet OOP just screams monster. Should I have just folded pre? Are players these days ever doing this as a bluff? I can see it being effective.

This is AA almost every time, certainly often enough to make folding here easy.

Don't like the 3bet sizing, I think flatting behind here is best unless they're derpy but if you think they're awful 3betting to 370 or so is better.

Folding to the small 4bet
