I could be way off but I'll take a stab. I'm going to assume they are relatively competent or else this analysis is utterly useless.
This hand really depends on a couple factors for me:
1. How wide are they defending bvb? I'm going to assume 76s and 54s are in their range, but are they capable of defending as wide as 76o, 54o, J6, or J7?
2. Are they capable of bluff shoving missed flush draws? There are people with laggy preflop stats but won't felt hands unless they have the goods.
3. Are they capable of slowplaying hands on semi drawy boards to mess up handreading, primarily 76 and potentially J6 or J7 which are quite vulnerable on the turn and should generally be raised?
Their line is very very strong and if they rarely bluff shove, call me a nit but I'm inclined to fold.
Hands that beat you: 33, 66, 77, 54s, (54o)
Hands that you beat: 76s, (76o), (J6), (J7), (bluffs)
Price to call: $63.5 to win $142.5 so need to be ahead 31% to break even and probably around 33% to make this a call.
Doing this with Qx is pretty lol and I think someone with an aggression factor of 5 raises Qs6s on the flop. Any other Q6 folds to the second barrel so for all intents and purposes, the river Q is a total brick except as a scare card to bluff you off Jx. Doing this with any one pair hand is essentially turning a weak made hand into a bluff because they know they are behind.
I would personally always raise J6, J7, and 76 on the turn but that's me.
Using combinatorics, relevant river value shoving ranges (range and combinations of hands we beat and lose to followed by how often they need to be bluffing to make the call profitable):
33, 66, 77 (ahead 0, behind 9): 5 other holdings or 36% bluffing frequency
33, 66, 77, 54s (ahead 0, behind 13): 7 other holdings or 35% bluffing
33, 66, 77, 54s, 76s (ahead 2, behind 13): 5 other holdings or 25% bluffing frequency
33, 66, 77, 54, 76 (ahead 9, behind 23): 4 other holdings or 11% bluffing frequency
If you add any other two pair type holdings, this is a snap call.
