Just raise the flop because hes cbetting mw so his range should be stronger and therefore less likely to fold. As played would probably bet a bit larger on the turn and calling the x/r to hit a boat . Seems quite optimistic on the river to assume he's x/r AcX into a range that is quite strong. I don't think this line gets bluffed too often either and this guy is a tight reg. You also get here with a lot of flushes so wouldn't mind just folding this hand although it is exploitable (but you're also exploiting population underbluffing this spot)

I like the call on the flop, we want to keep a lot of hands in the game that will easily foldto a raise.
the turn I would certainly bet bigger , I think pot (or more) will be fine here, lettting him pay for his draws, now his reraise can also come because he perceives your bet as weak.

When he still reraises you than you can look at the odds you are getting and decide to call of fold.

As played I m definitely folding river

I would look at his agression on later streets - if he is still betting with high frequency on turn I can consider calling flop to raise on later streets, but usually I think it has to be raise as he is betting less than 50% pot.

As played after bet/calling turn you have yourself many flushes so I have no problem folding with set.

MP can have around 12-14flushes as you already did equilab. His sizings tells that he has flush for value, and nothing worse. It is quite funny line by him, not necessarily bad but someone like 20/15 will have hard time bluffing enough or try hard to fold sets on the river.
Best exploit vs people like that just to overfold postflop.
