The table was extremely loose, because we had 2 loose maniacs there (the Villain about 330 BB deep) and people were gambling with pretty much everything ... as they always do in micro stakes

Hero was holding AxAs8s7x BB about 215-220 BB deep. The maniac sitting on the seat just before him on SB.

Preflop: 2 people limp, MP pots and everyone calls. (I also flat called)
Flop (33 BB) 6-ways Qs6s5h

SB pots 33 BB. Here the Hero should be favorite even against the top set and in my basic understanding tells me that we have two ways to play this hand. Either we raise pot and try to get it in as soon as possible or to flat call and lure other players in as well, because we really cannot fold that hand I reckon ... unless the board pairs on turn of course.

Anyways the Hero called and everyone else folded.
Turn (99 BB) heads-up : 2h
Hero has 178 BB behind

SB pots, hero ???

My initial plan was to just call the bet off if the board does not pair, but in the end decided to shove instead. Villain calls and shows JsTs6s6 and Hero has about 33% chance to win the hand.

I found this video on Youtube where the described situation is rather similar. I hope that I may post it here:

What are your thoughts about this situation? Is the shove on turn justified or should the hero just flat call there again?

Raise pre flop , raise flop .
Passive play can't win this game .
On the turn you're probably never favorite against a psb so no point of shoving .
I would do opposite then you on every street.

Just pile it on flop vs maniac as played. Someone else might still stack off.

Raise pre, raise flop, print money. I think shoving turn against a maniac is fine.

Having 78 makes a 3bet much more attractive and you should be 3betting this basically 100%. You do want some bad AA in your flatting range but you really don't need much of one. If you 3b all your suited AA with any sd you'd be doing absolutely fine.

With the table dynamics as described I think we should flat the flop.

I haven't looked at these numbers in a while but my recollection is that no, we're not a favourite versus top set

Why would you like to flat the flop ?

Because the more people in the pot, the bigger a pot we can win. The outs we have to hit to beat a set are the outs that will scoop regardless of whether we're headsup or multiway, ie there's no outs we need to clean up. We can also call it off again on 100% of turns

Hands way too strong to flat and especially at this stack depth and OOP.

We almost never flat AA OOP sub 200bb

We can comfortably jam this flop too whether potting or XR.

5% dog vs top set , echo three bet and push equity on flop
