I think ranges are fairly symmetrical on this flop. You both will have a bunch of Jx, but given the stack depth, position and potcontrol are a bit more important with a lot of your range than it would be at 100bb deep. So I think you will need to be checking a lot here, and I think Ac7c is likely a mixed strategy as well.

It's fine as played imo, and I probably would just ch/call on blank turns, since I expect most regs to giveup their bluffs OTR, also I don't think they would be too bluffheavy.

Wp, x/calling is fine and never wrong mathematically. X/raising would be a waste and bet/alling with these odds is fine as well.

So it's better to show more V's info. then we can discuss more value here.

I think this hand was played fine, I really like the 3 bet pre with the A7s, btn ranges are pretty wide so I like to mix in some different raising hands to mix up my game. flop I might go for a check call or even a check raise depending on the opponent. The turn was fine too because theres no point leading, if he felt confident enough to bet flop then the turn changes nothing.
