99 vs. TAG w/ overcards

[UncleSalty]

I'm just getting started at 6-max, and post flop is still confusing me. At full ring this is obviously an automuck on the turn.

Villain is a TAG after only about 40 hands at the table, so no real read. Can I let this go to the turn raise? Calling down felt like spewing. How aggressive/maniacal does a villain need to be to justify calling this down?

Thanks.
