I don't understand the question actually.We're not the agressor pre-flop so how can we cbet the flop?Do you mean leading flop?

Yeah you're right, I must have read it wrong when reviewing it (wasntme). I'll change the question to - should I float this flop with only ace high?

ATo is an easy call BB vs BTN open,but offsuit raggy aces make a terrible 3 bet OOP. Use some weaker SC's, suited gappers and Qxs Kxs that don't make such good calls, asyour bluff range.

As played I'm giving upon the flop with just a single turn card that I'm half happy to see.

I think with not many backdoor possibilities it will be hard to continue on many turns.It's close.It depends on villain's turn and river play.If he's barreling a lot it's ok to fold on flop.Sometimes you should be able to take agression on some turn cards if you're floating wide on the flop.You need to be aware what do you represent with the float.

First off - 3betting here pre makes no sense unless you think villain is a weak player who'll call super-wide. Then we can maaaybe 3bet for value, though I'm pretty still pretty sceptical and would make AJ the bottom of my value range.

As played, I'd just fold flop. If you were IP floating might be okay as you can get to showdown easily with your Ahigh. Not the case here, and if I'm villain, I'm barreling a ton of turns and there's not much you can do. Floating OOP is not something you really should ever be looking to do at these stakes in my opinion.
