$1.5/4 game, blinds are 10/25 foreign currency.
MP is a superfish. Call a 3-bet all in with 2 overcards to a flop earlier, and went runner-runner wheel.
MP+1 is a super-LAG. Opens/3-bets a LOT. Got busted earlier and bought back in for a lot. Been a maniac since.
MP+2 is a super-calling station. He's always calling the super-LAG's raises/3-bets.
SB is an average non-descript player.
H is extremely card dead and has been folding a lot. Lost a semi-big pot to a river gut-shot that made no sense, and another big pot to a 3-bet by MP+1 when he had K6o and flopped top 2. Hero has 1900, everyone else covers. H recently 3-bet all in PF for ~1000 with AKo, got called by MP+2, who also had AKo, and chopped the pot for about 300 profit each.
MP opens for 150
MP+1 calls 150

Hero?
1. Pre-flop bet sizing? Do I want more people in here? Should I 3-bet less? Shove? Should I ever flat here?
2. Infer anything from MP conjecturing that I may have AK or AQ? Is it more likely he has AJ?
3. Hero has about 1/2 pot behind on the flop. Hero?
