Middle pair OOP - what's standard?

[MrStretchie]

This is a fairly standard situation - just wondering what people consider the default vs a decent but not outstanding player.

Hero is in the SB with Q[img]/images/graemlins/diamond.gif[/img],9[img]/images/graemlins/diamond.gif[/img]

1 limper, villian limps in LP, Hero calls, BB checks.

Flop is T94 rainbow.
Hero bets, 2 folds, villian calls.

What's the plan from here? I know this is a pretty standard situation, so I really don't mind 2-4 word answers. [img]/images/graemlins/smile.gif[/img]
