200NL: KK flop decision

[Stonewalled]

1/2 NL live, 10-handed, at St. Louis Harrah's.

3 Villains in this hand are all loose old guys who play marginal hands, and take them too far. The one who raises on the flop is very aggro, raising a bunch of pots and playing junk for a lot of money. The others are very passive.

My image is TAG, and I've shown-down only good hands.

My stack is $550. The 2 loose/passives have about $150 each. The 1 loose/aggro has me covered.

Hero has KK in BB.
Preflop: Loose/passive #1 is UTG and raises to $15, gets 3 callers, including loose/aggro in MP, and loose/passive #2 to my right, Hero raises to $75 (I meant to make a psb raise, but I miscalculated the pot), the 3 Villains call.

Flop (4 players) ($320 pot): Q93 rainbow
Loose/passive #1 bets $10, loose/aggro raises to $60, loose/passive #2 calls, Hero ???
