So I run into this situation a lot where I simply can't find enough bluffs on the flop to end up with a balanced river betting strategy. I'm pretty new to attempting to play unexploitably because to be honest at my current stakes it is not necessary but I'm trying it out so I don't get crushed at higher stakes.

For our range if we say our value hands (betting this) are: AA JJ 44 AJ A4 AQ AK
and our hands to protect our checks include: All other Ax, Jx, KK, QQ and maybe like 64s
Then our hands to barrel as semi bluffs are: QTs KQs KTs 65s (w/backdoors).
Where do we find the rest of our bluffs that make sense, do we just use our weakest pocket pairs along with shitty offsuit gutshots? Otherwise our bets are heavily value weighted which is like the opposite of what it should be on the flop. How much does it matter that we are value weighted in this spot?

Any help would be greatly appreciated.
