I don't play these stakes but this hand seems like a pretty good candidate for check/calling the flop to me. Wouldn't you rather like to x/r some fdraws, straights and sets?
Can you give your thought process for raising flop?

I'd prefer calling on the flop, raising might be fine in some situations versus certain opponents.

As played I would bet the turn. We don't have that much showdownvalue with my hand, because villain will probably bluff us off with worse hands if we check, so we might aswell turn this hand into a bluff. I would use a smaller sizing though, because I want to represent sets more credibly (more valuehands in our range, harder for villain to bluffcatch).

I think A5 works here much better as XC. If you hit A on turn, you are likely to win large pot.
I think turn is a good card for us, we will have 6x bluff XR on the flop for sure (at least hands like T6s, 96s). So there is no merit in betting there only our str8 and all unimproved bluffs.
But to be honest, it's hard to think of hands which we are going to bluff here... Certainly we want either blockers or equity.
For blockers bluffs maybe exactly 5x and 7x are good to block 76o and 65o... So looks like a reasonable bluff to me on the turn in the end...
For equity bluffs I belive we should have smth like runner diamonds. But I am not 100% positive that I would not check here all my flush draws expecting villain to checkback a decent amount here.
So yeah, I'd rather bluff blockers here then with equity, and I think we should be jamming any river unless clubs fall on the river.

This was tough to write, I might be completely off.
Im not sure if the flop is a valueraise or a bluff raise?

1)villain is unlikely to cbet this flop with air and given the amount of draws in your perceived range/his range composition, you're probably very rarely getting a fold otf. There are few good turns for your range, why would you bloat the pot oop vs a strongish range?

2)That said, A5 is def. strong enough to call at least once. First, villain still has a fair bit of draws in his range. Once you xR A5, the hand moves to the bottom of your range, which makes it hard to play versus a pressure that a draw can put on you. When you call, the pressure that the draw can put is limited. Second, your xC range should be able to cover most runouts here (you xC some FDs, you have 6x combos to xC (76,65), you have some overpairs and hands like K7...), so it shouldnt be too easy to barrel you off your range, so I wouldnt worry about xFolding A5 on certain turns.

Like I'd xR Ac8x otf much rather than A5...

So you were playing this hand as a pure bluff and got looked up. Ok. I get that. I was reading a value line into your post at first.

Personally, I'm check calling 1 street and reevaluating if I get to the river....which I don't expect to.

Blind defend is good.

x/c turn ,
not idea why lead
