HU good push?

[TheSalche]

Villain and I are about even in chips with me having a slight advantage (t290 on PP $10+1). He has been playing pretty solid and I've been forced to lay down some good hands to his raises.

blinds 100/200
Hero dealt: A [img]/images/graemlins/spade.gif[/img]Q [img]/images/graemlins/spade.gif[/img] on button and raises to t600, villain calls

Flop: 2 [img]/images/graemlins/spade.gif[/img]3 [img]/images/graemlins/club.gif[/img]7 [img]/images/graemlins/spade.gif[/img]
Villain bets 1000, Hero pushes, villain calls

my thoughts were the best he had here was a pair, if that is true i have a 15 outer to win

do you push here or do you wait for another hand?
