AK TPTK vs All-in flop

I would break my mouse calling given his stack size.

This is why I like playing normal tables, any info or reads makes all the difference in these spots

Hey. I would 4bet to 1.80 to collect dead money from MP. I’d stack off vs BB (not a full stack) and consider fold vs jam from MP (limp-jam is nutty line). As played, Bb line looks like aces or kings. IME overbet like this is rarely a bluff.
He had aces didn’t he?

You cannot fold OTF. Cannot. I repeat: you cannot fold. No.
AK is very close to the top of your range. You don't have AA or KK.
Stop being results oriented.
Edit: 4betting preflop is a very decent play and my favorite.

Snap call

Pre-flop you should 4-bet and go broke if there is a shove. With an exception if you 4-bet , BB shoves, MP does not fold but re-shoves or flat calls. If flat calls proceed with caution on flop

Sets or aces are possible, so is A7, A5, and pretty much any other two cards you can name.
You have an ace, so there is only 3 others out there.

zetozinho has it nailed.
