Preflop I make it 80 as well in this blindlevel, just for value and because they are never folding to 20 more chips anyway.
Flop is a standard continuation bet, and after his call I usually barrel on the turn here as well.
We can assume that we are good here almost every time, and if we get raised on the turn it's usually not a float and I am able to muck my hand at that point against reasonable players.
And you usually don't want flushdraws to get out of the hand, but just let them pay too much to chase their draws so that they are making a mistake by calling.
On the river the flush arrives, and I prefer to check behind here all the time, because I don't want to run into a check/raise (as planned here) and I don't see much value in a bet, because villian alomst never calls a single pair of jacks on that river card.
As for the opponent, I donk this kind of flop and try to get it in as soon as possible with my ~1mio. outs
