TPTK faces check/raise from unknown aggro

[***]

Villain is basically unknown, but fairly aggro. I have his stats at 21/8.5/oo over a mere 30 hands. Not much has happened between us, but the last time he check/raised me on an innocuous board I folded my air.

I considered a few plans but I wasn't sure which one was the best one. Note that we are a little bit deep, but after his check/raise he'll have less than a pot sized bet left if I call.
