Let me rephrase my prior post because you online guys aren't used to playing limp pots and seem to be playing this hand like there is an invisible $5 chip in the pot.

The flop raise is spew unless the SB is stabbing at lots of limp pots. Even that said, a monotone, uncordinated Ace board doesn't exactly fit a small blind trash range. So we should tend to give the SB credit for a pretty strong hand here, barring more information.

By bluffing him we're fighting over a small pot and risking building a big pot when the kinds of hands we figure to make won't figure win multiple big bets (unless he's really stupid, which he's not) when we hit as we are drawing to a flush in plain sight and 2pr/trips.

Call flop, we have equity, position and can rep a bunch of hands on the turn. If he thinks we're floating then our gin cards get paid. Also, I don't mind an UTG over-call as it looks like he's pretty terrible (yet another reason this flop raise is online aggro monkey poo flinging.)
