I don't mind defending with K-9 here pre. Against a guy with a half stack in the CO (for some reason people with less than 100 BB are usually weaker players IMHO), I think we can navigate well post...
However, I fold flop. If we C/R, and I am saying if
we C/R, if he calls, he's not folding after that. And C/R should be bigger. Like 2.5x~3x. However, we are saying we have 3x here, and if V doesnt buy it, we are lighting money on fire.
Not to mention, if we think there's a possibility V is a weak player (based on fishy stack size) he is gonna call, and call some more. Not a great target for bluffing
So, we just avoid the cage. Fold flop, or C/R bigger. I just fold flop. On to the next hand.
