So i was looking at it with a solver and gave him the following range to flat after my 4b

99+, AJs+, AK (50% of the time offsuit jammed, while AKs called 100% due to playability)

I tried to find some rule of thumb for what hands like my weakest 4b bluffs I can bluffjam the turn with on blanks (which I would do with QQ-KK as well to get value from his 99-QQ). Maybe you guys can share some of your insights from analysing such spots and if it makes sense.

-- If a second suit comes from the board (such as in this case the 8h), I would jam as a bluff all combos that include a heart in it. Granted the Th blocker wouldnt make much sense with that flatting range, but the idea is that we block any floated AhQh, AhJh, AhKh that could find a call.

-- If a blank with the fourth suit comes in (8d), I would be prone to bluff jam all combos that have the Kd/Td in it (to unblock the other floats with a backdoor flushdraw) and therefore get better SDV to fold.

Obviously im never doing such a play if they are not capable of folding some of their weakest overpairs next to those AKs/AQs/AJs floats, but think its a valuable move. Or you would expect to even get called by regs here with all of their overpairs?
