Lay Down 2nd Nuts?

[TakenItEasy]

Wynn $2/$5 NLHM
Hero is BB with around $600
EMP has around $600
LMP has around $400

6 limpers, I check with A5o

flop 234 two tone, (not my suits), 2-4 suited.

Hero checks, EMP bets $20, LMP calls, Hero raises to $100,
EMP calls, LMP reraises all-in, hero?

Read on EMP is he is young and not too experienced, He really liked his hand based on how he handled his chips with the lead off bet, he seemed less certain with the call of my CR, however, he looks commited to stand his ground vs 2 of the more aggressive players at the table. I think he has overvalued his 2 pair.

Read on LMP. This guy looks like a biker with tats, shaved head, pot belly, but brighter than he looks. His starting range seems to be pretty solid but he is definately aggressive after the flop and has fired 3 round bluff attempts on dry boards but never into strength or even on a danger card. While I read his bluffs before through breathing tells, he now looks extremely confident.

Hero?
