preflop spot

[PokerBob]

i asked two experts about this spot and they disagree. what say you?

some background is necessary. utg is Lundy or Lindy or something like that. she is horrible. in the previous pot, she rivered a set of Ts after c/ring the preflop 3bettor on a J high flop. the 3bettor looked like he had a better hand until the river, at least based on his expression when she tabled her hand.

the 3bettor in that pot is some white dude in his late 20s who i initially assumed played OK, but then saw him overlimp T2s in MP. he seems prone to tilt (or at least getting a bit loose when stuck), and is clearly an idiot on some level.

UTG+1 is just some guy who probably is a breakeven player. his name escapes me. he is an idiot, but not a raging lunatic.

the hand:
commerce 1/2
Lundy raises UTG, UTG+1 3bets, folds to titlboy in the hijack and he cold-caps (this is the 3rd hand in a row that he has raised, but the others i didn't get to see what he had), CO (a pro who has been on TV and stuff) calls 4 cold, folds to me in the SB with black JJ. wtf?
