Flatting AA preflop

Flatting AA in position vs a 4b seems to be something the GTO solver likes alot

Is that something regs are doing alot?

why does this make sense?

It makes sense because you let villains try to bluff you out of a very big pot and/or value bet worse hands

€0.25 NL FAST (6 max)

BTN: 47.96 BB
SB: 100 BB
Hero (BB): 100 BB
UTG: 114.92 BB
MP: 92.6 BB
CO: 103.12 BB

SB posts SB 0.4 BB, Hero posts BB 1 BB

Pre Flop: (pot: 1.4 BB) Hero has A A

fold, fold, fold, fold, SB raises to 2.52 BB, Hero raises to 10 BB, SB raises to 22 BB, Hero calls 12 BB

Flop: (44 BB, 2 players) 4 8 Q
SB bets 11.28 BB, Hero calls 11.28 BB

Turn: (66.56 BB, 2 players) 3
SB bets 66.72 BB and is all-in, Hero calls 66.72 BB and is all-in

River: (200 BB, 2 players) K

SB shows Q K (Two Pair, Kings and Queens)

Hero shows A A (One Pair, Aces)

SB wins 190 BB


Agreed, when we 5bet we fold out 99% of villains range, so flatting makes sense.

I had almost this exact hand last night. I 3 bet preflop and reraised the flop. Also got it all in on the turn


I don't see solver flatting much AA vs 4B tbh


It's only BB vs SB, were AA is a pure call vs 4b. Else it's done at a very low frequency. I'd say the solver protects its call-range vs 4b with doing so.


In my experience players don't 4bet enough from the SB in BvB. They simply don't have as much 4bet/fold hands as they should have. I jam and expect to be called a lot.

I'd only flat here if I had prior evidence that an individual villain was capable of 4bet/folding here.


Optimuspoker solver flats AA from BB vs SB 4B


Optimuspoker settings : low stakes 100bb deep, BB vs SB 4B


By 4 betting you let the light 3-better off the hook, if he is likely to spew off post flop. It is especially nice when you will be IP.
