10/25 Non-nut flush spot

[4CardGrind]

OK here is the table set-up. Two tables of 25/50 running, they are both getting deep quick... same players on other table with gimme_nutz being 40k deep there. Applsgirl is a good aggresive player I've played with on full tilt and UB at 10/20(5) but never 25/50. When I went to bed last night at 3 am earlier I had just checked the tables for any good action. Applsgirl was playing at this time, and playing when I got up as well.

The avg pot at both tables is between 2k and 2.5k... games are 3-betting often and loose.

Given these conditions, how do you play this hand preflop, flop, and turn?

His range gets quite small on the turn, A high flush or dry A right?

Just been in these spots alot and never really know what the correct play is.

Happy thanksgiving guys.
