Don't have stats available for villain as of yet.

Villain is pretty bad, seems donk-ish post flop and I've 3bet him a ton preflop and he's called most 3bets. He's folded most of the time on the flop. [3/5ths pot is my standard in a 3bet pot HU]. My hand's never good here, right? And if it is good, I'm only slightly ahead?

Villain might have got spazzy because I requested time for a while before finally deciding to bet. Should I bet here, or check hoping he spazzes out with smaller pocket pairs?
