Your line is perfectly fine. Villain has a lot of Ax that he can play this way and it's not a spot where people go out of line with their bluffing frequencies.

Looks good. Also if we want to call some Qx here I'd prefer if our second card not be a spade just to give him a few more missed fds.

So the biggest thing i think we need to consider is what our range looks like after checking the flop. If we bet all of our aces then were capped at a pair of queens on the turn with some 64, 43, 33 and maybe 66, and im notneven sure if we shouod get to the iver with 66 there. So a pair of queens would be fairly high in our range and we would need to consider which ones to call and which to fold, i still think im olay letting go the ones that block the FD that hard. That said, the more Ax we check on the flop with, the more Qx we can fold so figuring ouf these frequencies is job #1
