BB special faces lots of aggression

[tree_stump]

Based on his line and no other reads, I'd have him on one of a few hands:

JJ, J2, KJ, or AK
Misplayed AA or KK
Club flush (though I'd expect this to be very rare, because it's so awful)

Given that, I'm either folding to the turn c/r or letting the turn check through, then either check/calling or check/folding the river. You may be ahead, but IMO it's not worth chasing, since everything outkicks you and you can't be sure than another K wins you the pot.
