I'd give them the following range: 8x, over pairs, OESD/flush draws and then 7x.

Can't see myself folding here on a paired board, GG if they hold a 7.

Spot on by harvie. We can never fold.

I called and villain showed J7s.I wasn't thinking about folding this hand but while I was discussing this hand with a friend he came up with the idea they never check/raise worse.That's why I wanted open a thread about it.It's possible unknown can check/call 3 times with an over-pair also it's possible they can check/raise shove on paired and two-way flush draw board I assume.

It's tough to ever fold this in a 3 bet pot once you bet twice and he can have worse overpairs. Factor in straight draws and flush draws which miss the turn as well as turned clubs and it's a relatively trivial call getting those odds.
