Good player pushing CO party 300k

[wtf5]

villain is berg114 in the party 300k and seems good. He's pushed from CO and button before into short stacks (less than 10 BBs) and taken them down. Im sure hes pushing a wide range but i don't no if my hand is quite good enough.

If hes pushing top 20% this seems a fold but im not sure how wide hes pushing.

Thoughts?

I was railing OP here, and the villain was 27/19 ish over a couple hundred hands fwiw. I wouldn't neccessarily describle him as good, but obv very aggro.
