This is a discussion on $2 NLHE 6-max: Hero w/ AK 3-bet 15BBs -- Faces 4-bet shove for 123BBs within the online poker forums, in the Cash Game Hand Analysis section; NO INFORMATION ON VILLAIN
hero holds blockers to AA/KK
hero thinks its weird that villain from the SB would limp the UTG open raise, then
Flat/4bet shove out of the sb is a weird line for sure. I can't fault the call, but I think I'm folding. Too many times I run into AA or KK here. You are flipping against all other pp's and are only 65% against unsuited, unconnected cards. You're going to have better spots against this villain. Call may be positive ev though.

For starters its a $0.02 game on the Winning Network. No one playing there is in danger of winning the World Series of Poker Hero is behind AA & KK, flipping with all other pairs, 60/40 favorite over other suited connectors and dominating other Ax hands.
It increase variance, but I slam it in too, expecting to see QQ.

Pretty standard call IMO, given the action. Smells like a small pair, 88-JJ type stuff. Kinda shocked to see KK (hide the results next time).
Make a note, move on.

Its such a small pair spot,
In that spot its one of two things someone who thought they might try and be tricky by flatting with a big pair or people who just cant fold small pair..
Always going in.

This kind of backraise CAN be AA sometimes. But the positions here are pretty telling. Unless SB has some reason to specifically expect you to 3bet a large amount of the time, which he shouldn't, since you said there's no info.
I expect someone to flat a single raise with AA or KK MUCH more often when it's EP vs EP or even MP vs MP rather than SB vs UTG. I realize you are 5-handed but I'd be discounting KK+ a lot.
I expect to see mid pairs QUITE often (which we are fine against) and occasionally an AJ-AK type hand. I gladly call it off and make a note as others have stated.
