Calling tight AA heavy 4-bets 100bb deep


Until shown otherwise assume people are only 3betting AA and strong KK unless they are being spewmonkeys over a larger sample and you have strong reasons to assume otherwise.

Double pocket pairs:

  • If not connected must be ds, ex. TT44ds. If connected single suit is okay like 9977ss. 150bb deep or greather also connected rainbow is okay for ex. 9977r or TT44ss.

Single pocket pairs:

    • If connected single suit is enough, ex. 9987ss. EXCEPTIONS are KKQJ/QQJTss which NEED to be double suited because of the proximity effect unless 150bb deep.
    • If unconnected like KK87 MUST be double suited. 150bb deep decetly connected like KK87 can be calls and also totally unconnected hands like KKT4 become calls if double suited.
    • If containing an ace MUST be double suited and connected like ATT9ds and below while AJJTB/AQQBds are still folds because of the proximity while 150bb deep we can start calling.

Non-ace Rundowns:

  • All rundowns are ofc calls, the only thing to note is that even rainbow rundowns become calls 150bb depp+. Marginal hands like KQJ*ds are breakeven calls.

Ace-containing Rundowns:

AJT9ds and below is a call, else fold. Also fold all the unconnected double suited hands. A987/876ss can be calls 150bb deep.


SPR 1 means we need 33% equity to stackoff. That means 8 clean outs on the flop (8 x 4 = 32%).

We get those 8 outs already from having one bare pair OTF so we should be calling in that spot:

Ex. villain 4-bets us, we call with a rundowns with which we 3-bet, spr otf = 1 and villain pot bets allin, we have a pair ie. two pair redraws versus villain overpair

If there’s an ace on the board making villain top set in a 4bp we still need 8 outs, BUT clean outs, because some of the time villain will make full house so that means in reality we need 11 outs at least that is FD+gutter or 12 outer straight draw.

If we remember studying cheat sheets for playing vs 4bets with a range of only AA**!AAA. Against that range I learned that we should defend ABB9 or AQJT and below only if double suited and if we’re 125bb-150bb+ deep.

So seeing a 3b here made me want to fold at first glance since villain is tight and we have an Ace(dangler). Then I remembered that 5-6% 3b range isn’t only AA**!AAA but mostly strong aces, premium kings and strong suited rundowns but I was still erroring on the side of folding.

Then I pluged in some numbers:

HU vs a pot sized 3b we need 33% equity to call(not factoring in that we’ll be OOP postflop and won’t be able to realize our all equity) so vs AA**!AAA range only it’s true we should fold this hand since we only have 29% to begin with.

Hand |Pot equity |
AhKdJh8c|29.70% |
AA!AAA|70.30% |

Then I took 4% and 6% 3b IP ranges from PJ to see how I was doing:

Hand |Pot equity |
AhKdJh8c|43.92% |
3bIP6%|56.08% |

Hand |Pot equity |
AhKdJh8c|38.20% |
3bIP4%|61.80% |

As we can see it’s a clear CALL against that ranges. SO be careful to differenciate tight 4bets from tight 3bets. How to play in 3bp you can find here.

How things change when another person joins the pot giving us better odds?

Hands that are folds 100bb deep but calls 150bb deep now become calls when 3w 100bb deep:

AQQJds or ATTxds
TT44ss or 9977r
ABB9ds or ABBBds
KK87ss or KKT4ds
