help me understand - overpushing big draws

Stars 1/2 NL, effective stacks $200 all around.

UTG is a typical learning TAG, who tends to nut-peddle. Opens pot for $10. All fold to Hero on the button with 8[img]/images/graemlins/spade.gif[/img]7[img]/images/graemlins/spade.gif[/img]. Hero calls, blinds fold.

2 to the flop for $23. Flop comes 6[img]/images/graemlins/spade.gif[/img] 4[img]/images/graemlins/spade.gif[/img] 3[img]/images/graemlins/diamond.gif[/img]

UTG bets $23.

In this scenario, against this opponent, I push.

several respected posters noted that this was "perfect", but i can't quite get my mind around these types of situations. Pushing $190 into a $46 pot seems wrong to me. If this is really the correct play, what do you do different with 6[img]/images/graemlins/heart.gif[/img] 6[img]/images/graemlins/club.gif[/img] or 5[img]/images/graemlins/heart.gif[/img] 7[img]/images/graemlins/heart.gif[/img] here, and why? I feel like there's something i'm fundamentally missing here.
