Based on your read on the re-raiser, I fold, but VERY grudgingly and only because of my read. you are not beat by KK or AA, as you would have been re-raised. You are beat by 99, a hand containing a 7, or a suited club hand such as K9, or A9 (but I hardly think people at this limit realize those 2 are winning here against your overpair).

problem is lets figure the hands you do beat that would make might make this move: jj and 1010. the other is an unsuited hand with a 9, but read on villian says no here.

maybe its jj or 1010, but based on read on villian there are more hands that beat you theoretically that make this move than hands that dont.
