So I was a bit lost on how to play this, pre flop I remember that AQs is a flat 100% of the time, so I decided to to it with AJs as well although chart says should 4bet at some frequency.

Anyway turn is standard, I think he stabs all flush draws, and some middling pairs and continues most As. So not thrilled but continue for at least one street.

Turn facing a check is where I have decision.

I think most of the pool would bet to try and deny equity, but realistically he is never folding unless it's a shove, and he is continuing with all his Aces I imagine so I think checking often is a good play here. By doing so with a lot of middling aces I ensure I have some hands I can call safely on river. I have some AKo that I think it's worth to shove along with some AQ and KQ.

But mostly at these stakes I think a lot of players with Vs stats are trying to get fancy on river but I don't really know. What your strategy on this turn with your range?
