Hey,
i kinda like your line even if i like to just call flop and keep all of his bluff range continue. But raise it's good either.
As played, i think no one , and not a fish gonna try to CRAI here in bluff. His profile like to call, so when you raise flop , bet turn and bet river , he has something. And because you have the nut flush.. I mean, he gonna just call under flush or Q Trips and RAI full.
Hope i'm not RO , and in game i think i would have called either, but with thinking i don't see some bluff in there even if you have the best bluffcatcher.
Sorry for my english, first post on RIO and i'm french tho :)

I think the flop raise is a little big, I like to keep it around 8-10 BBs, you don't really need to worry about MP+1 calling light. I also would probably call on the flop, as donk bets usually don't have the strength to call such a big re-raise without hands that have you beat by a lot.

Turn I think we can raise as well since he's leading again on a flushed board after you showed a lot of strength. Since you have the Ad, it's hard to put him on a semi-bluff, it's more likely he hit his own flush, he's trying to either protect his non-flush hand or bluff you off it completely. Obviously you are showing a ton of strength here but assuming he's competent he should have a fairly strong range here.

I don't think we're folding the river. If anything, I might shove the river since it's about a 80% pot sized bet and we get calls from all Qs and worse flushes

I like everything here except I would have raised the turn. I think he almost always has two pair+ or a lower flush here, and I'd like to get more money in before another diamond or pairing card ruins your action.

Well, this is a fist pump fold pre in a 8 handed game utg+1. You have A2.
As played I think shoving turn is best. To get value from some pair plus/and draw hands and not loosing action to smaller flushes (which he prob have alot of here) when the river is a d.
