QQ facing Check raise shove

1/3 NL. No good reads here as V in this hand has only been at the table about 20 mins. Hasn't really been involved in anything yet. Older Asian male with about $350. 2 black chips and a mix of green and red so possibly someone that just came from the pit games. Hero has V covered.

V UTG raises to $10. Folds to hero who 3 bets to $30. V calls. Heads up

Flop ( $60) 7c 5s 3c. V checks. Hero bets $40. V raises all in.

Hero?
