5-10 NL Hand at the Wynn

[Daliman]

A hand came up at the Wynn I'd like to get some votes and opinions on.

The game is 5-10 NL, and you have ~$1300 in front of you. The game has been pretty standard mix of loose/decent play preflop, bet/takedown flop, and is 8 handed at the moment. The player 2 to your right opens in mid position for $40. You smooth call to try to trap with QQ. Folded around to the BB, who raises it to $120 after about 20 seconds of deliberation. Mid position opener thinks for about a minute before calling, and you decide to raise it an additional $400. The BB, a younger looking player who has yet to show down a hand, has been playing for about an hour, has been talking genially with others at the table, and seems to have at least a decent idea of how to play, looks a bit concerned, but after about 30 seconds, decides to go all in for 610 more on top of your $520 total in. The MP player folds quickly, and it is up to you. The pot now has $1775 in it, and it is $610 to call. What do you do, and what is your thought process?
