What to do with TT facing a huge 3B pre?

Played this one last night. Not sure how I screwed this up.

2/5 (10 straddle every hand), $1k max. 9 handed.

V in SB. ~$900. Stuck on the session. Hyper-aggro white kid in his early-mid 20's. He's part of my circle of reg friends, so we know each other's game. He's usually playing a raise-or-fold strat with his entire range pre. As the pre-flop aggressor, whether he's IP or OOP, he's c-betting close to 100% of flops, barreling turn big, and betting river huge.

If I had to guess, I'd say he probably thinks he has a skill edge over me. When we've clashed in pots, I tend to over-fold. I know he has to be bluffing sometimes, but because of how he plays, and how high-variance it can be to play with him, I usually just stay out of his way.

H in HJ. just over $3k. Absolutely crushing it this session. MAWG. TAG with occasional punts.

OTTH...

One limp. Hero raises to $40 from HJ with TT. Folds to V in SB, who 3B's to $300. Folds back around to hero.

No idea what I'm supposed to do here. Never seen him 3B this huge. I feel like this might be a jam or fold spot, but if I jam, I don't know what worse PP's would call, and folding seems too nitty, given how deep I am and how good I've been running. So I call.

$620. Flop is KQrag rainbow. V jams ~$600.

Hero?
