Post should say HERO:????

Option 1: Shove: Feel we will be called and beaten often by QQ+, turned flush draws? Does Jx call here all the time?. Save getting bluffed off hand if we check?

Option 2:Check/call: We look quite weak checking the river here (almost face up as to JT for value and then floats that gave up, although I dont know how often i do that), so could expect to be bluffed by any broadway hand/ Q9/89/67 that peeled the turn with a draw? The rest of hands got there, but are there enough bluffs here? Can he value bet AJ ever?

Option 3: Check/fold: Because we  have a strong range on the turn we don't expect him to bluff us even if the river check looks quite weak,  we expect his peeling range to be strong Jx, QQ+, flushdraws and some straight draws. He checks back turn with maybe AK/AQ some of the time, while barrels his turned flush draws. QQ+, flush draws all now got there so should we now fold?

Option 4: Any other suggestions? Blocking bet? 

 2 and 3 are assuming he sets us in with our 7.5k stack and 12k pot out there.

A lot of stuff here but basically would love to here people's thoughts on the river options given the way the hand played.
