Guy is a reg who I've had a few hands with in the past and lost most of them. I'm not sure if he remembered since he's multi tabling but I ran a pretty bad failed bluff on him prior in the session at another table. Would checking turn be a better line? I thought this would be a good card to barrel and I block the A of spades and a lot of his Ax combos but but there are a lot of made flush combos for him to have as well such as JsXs. Considering how little people bluff at these stakes and the fact that he is yet to C/R turn before this hand means the chance of him having a pure bluff is very small.

what would you do with your nut flushes here OTT after the check if you have any?

tbh I'd probably still dbarrel here and x back Ax with more sdv/equity, like AsQx or As4x if you bet that OTF

After that x/r follow your reads and fold/3b dependent on opp's ability to fold a flush

I’m betting all of my flushes here at micros. Players are in general passive from what I’ve noticed so I’m getting way more value by just betting. Honestly I don’t see any player ever folding a flush at these limits. The rec players are pretty bad and the Regs are all multi tabling not ever thinking about folding a flush.
