I'd be calling that turn as they are kind of repping a flush and ours is not very high. Not a fan of jamming as I think we fold everything but 77 and flushes. Don't think they have 44/88/QQ as I expect these hands to raise flop.

Its a standard all-in. We are at the top of our range and we need protection vs his bluffs and we will loose a stack vs a better flush no matter what.

What bluffs do they have on the turn as the flush has got there? The only hand I think may be raising here is AhQx.

Ahx and Khx are the bluffs

I see and agree with your comment, but I don't think 5nl regs are turning them into bluffs given most of them play a tight passive approach. Very rarely will this take this line with semi bluffs at this limit.

I might have bet bigger on the flop, nearer 20c, but after that I'm not folding anytime soon, so if our friend has a better flush so beit, gg, reaload, move on.

Can also see him having worse hands for value like a lower flush, maybe the str8 or just a simple 2p or set that needs protection right now. Im all in on the turn too.

I think the flop is coordinated enough to expect sets to be raising the vast majority of the time making it unlikely they are a big part of villain's turn range.

With us only having the fourth nuts in a player pool where passivity is the norm I much prefer a call over jamming. I wouldn't expect a bare Ah to be a big factor here. Unless another heart rolls off I would just be calling down.

The way I look at these types of spots is that I'm not planning on folding such a strong hand and if we are beat then we will likely be going broke either way so I prefer sticking the money in here. If we flat call here we may end up losing value from villains potential set hands here if a fourth heart rolls off and we also lose value if villain has a hand where is is semi-bluffing with the A/K of hearts but as mentioned above, I don't expect them to be taking this line too often. I don't hate flat calling and playing rivers accordingly but I think shipping it on the turn is better.
