NL10: another blind v. blind hand

[appears]

Villain's stats: 21.05/8.77/7.33/114. I'm not sure what the flop overbet means. Is folding the flop weak-tight, or wise considering that two large bets are likely to follow? K8 beats only a bluff, but the unusually large bets seem to make a bluff more than likely.

This guy's aggr. factor is 7!! I am raise/folding that flop. If he calls and fires turn, i'm folding.

As played, folding the turn might be correct, but i can't do it against this guy. River is a snap-fold though.
