Playing at the Horseshoe Bossier City Friday. I'd been playing at a table full of nit regs (think Old Man Coffee x 8 ) and moved to a start up table. At the far end are a 25ish young man and his date, a cute apparently ditzy blonde. Neither knows much about poker (him-a little, her-nothing). He starts with 300, she starts with 200 and on the 3rd hand she doubles up through me when her set of Queens beats my set of Tens. We are all-in on the turn and she never bet/raised.
Now it's a half hour later and I have A

A

in the small blind.
One limp to the young man who raised to $15. His date calls. It's folded to me and I look down to see two black aces. BB is in for $3, so is the EP limper and the young couple at $15 each. $37 in the pot. $14 for me to call. At this point she has $450 or so, he has about $190 and I have around $400.
How much do I raise? We aren't even talking about smooth calling out of position to end up with a multi-way pot against people who cannot be put on hand ranges.
