50nl, AA in big 3-bet pot - QJ4 flop facing heat

[daven]

villain is relative unknown 30-10 over 50 hands at this point, but managed to 3-bet twice already in that sample. He was super aggro, so I knew he was betting any flop - I decided to give him some rope with the min-cr.

Struggling to put him on a range pre-flop, i figured high pairs? But his 3-bet was silly small so maybe it's 99+/AQ+? I think he's going to be keen to get it in with any of AA/KK/QQ/JJ on this flop.
Flop range possibilities
JJx3
QQx3
KKx6
AAx1

I'm pretty good against that range given SPRs and I have some re-draw potential against the set. Add a little bit of AQ/AK and it's looking fine to me.

I play bad?

Just stick the money in on the flop.

Easy hand, 90BBs 3bet pot and you have AA.

Don't make easy hands difficult.

yeah, I was never folding.

I was wondering what line would get a stack from KK... but given that he had AQ here, he sucked enough that it probably didn't matter what I did.

id either go with AAAAAARRRRRRR IN! and cry lucky if he hits hard. or check AAAAAAAARRRRRRRR IN!

i think ur check is very trixy but u risk him screwing with u and checking behind.

imo u need to make it so bloody obvious ur never folding so u take the pot right there. if they call and show u a set then they are making a loosing proposition with how effective stacks are after ur preflop reraise.

u dont pay him off enough to make his preflop call for a set profitable so u can give him the rest even if u lose even if he does hit because u take his money in the long run.

a preflop raise with AA is at worst about 75:25% favorite (SCs) and at best a 7% favorite (any two) and an 12.5% (lower pp and him FLOPPING a set.

you are mathematically correct in getting it in on almost EVERY SINGLE hand with a preflop raise this big.

imo check raise all in is perfect.
