Top two on coordinated flop, facing a raise.

[larrondo]

It's .50-1 NL. All relevant stacks are about fifty bucks. Table is been mostly passive and loose pre-flop. Hero is in MP and limps with 10 J off. MP 2, a loose and passive player, limps and the Villain on the button, a fairly tight (for this table,) aggressive and semi-tricky player, makes a small raise to 2 bucks. Blinds fold, Hero calls, MP2 calls.

Pot= $7.50

The flop: 9, 10, J, rainbow.
Hero bets $8.00 with top two. Passive MP makes a sad little call. He could have middle pair and an undercard, whatever. Villainous Button, however, raises to 30 bucks. MP 2 makes a disgusted noise-- he's going to fold. But what about our hero? Villainous Button could have trips or a straight, but might he have QJs or AJs?

What would your inclination be? Is it strictly read-dependent? Would your answer be different if there was a two-flush on board? How marginal is your decision?

Thanks for your insight.
