6-max NL25 TT facing all-in on raggedy flop

[Yorkshire Pud]

Villain is 31/19/infinity from 32 hands

Not really noticed anything out of the norm from villain but this all-in bet just didn't seem right but left me stumped as to what to do.

Was my line correct up to the all-in? Is 3-betting PF with TT asking for trouble? I'll post results if I get a few replies and they are wanted.
