2/5 NL Live

[djrect]

This hand takes place at the Foxwoods poker room at a 2/5 500max cash game. The Hero in this is a buddy of mine, who is a very tight but solid player. He is in for 500 already and after four hours just about even with 900 in front of him. The Villain in the hand has about 700 but no really good reads on him, just a consistent player.

Preflop the Villain is the SB, Hero is in the button with QQ, it gets limped to him he raises to 30. Seven people call including the villain.

Flop ($175 in pot) - K Q 5 (rainbow)
The Villain bets $125, everyone folds to hero, who re-raises all in?

My question is the hero's bet too much, what can the villain be betting with here? I will post the results later. I am just looking for any kind of advice on the hand guys. Thanks
