$40 live tourney: 99 flops boat, check-raised by unknown

[baudib]

guess this is a basic spot

early on about 25 of 30 remaining in live tourney

9-handed table, two limpers, UTG+1 and UTG+2, blinds 25/50

I have 99 in CO and make it 350 to go.

folds to two limpers who both call, so pot is 775 and I have about 3,500 left. 1st limper has 2,500 and 2nd limper has around 4,000.

flop:

they both check, I bet $400, UTG+1 folds, UTG+2 raises to $1,200

Hero?

I think betting this flop is standard as it probably looks more suspicious not to bet.

So I have essentially the immortal nuts but I'm wondering how to play this. His range is flush draws, Kx, pairs TT-AA, with the higher pairs probably being discounted. Villain is unknown, young kid who seems like he been at a table before.

I think anything I do here looks strong. Flatting with so little behind may look donkish though, he's not folding a K but he has a lot more combos that may not stack off.

Do we just flat and hope he makes a flush?

i think i'm flatting flop and checking turn,even thou that looks pretty strong, if your unknown to him maybe he thinks your a donk and were chasing for a 1/3 of your chips idk. i assume he never limp calls KK+ and probably pretty unlikely he limp calls 1010+ as well. i would say his most likely hands are KJ+, FD's and low pp/air that are trying to pick off a cbet. he's probably folding most draws to a shove, and if he has a king your probably stacking him anyways.

I think tanking a bit then flatting is best too. If he's on some bluff/semi-bluff he might just ship it in on any turn. Our stack is just a bit too big to shove IMO as he can probably get away from a lot of hands.

FWIW the average live player will probably think we are just like any other average live player. And thus think we cbet then tried to take a card off with something like QJ, TT, A9 rather than trapping with 99/AK/etc.
