squeeze KK oop, flop J hi - 50nl

opener is 17-9 and this is the first 3b i've seen him face. He seems pretty standard though and i expect his range to be something like AQs/99+ (some discounting on KK/AA i guess) when he calls
the call-call fish is 27-9 over small sample and likes to call. Doesn't raise much.

c-bet? or check-figure it out? as played fold?

As played I fold. I think co shows up with 2 pair+ here a ton, utg can have a combo draw or overpair. I think you played it well and probably ended up saving yourself some monies by not cbetting

This is such an easy easy c-bet

there is no benefit to checking this flop when you can pound it for value with the weak player in there - you can't necessarily expect him to do the betting for you when he has worse hands.

as played this is a 3bet pot, the weak reg just made a small bet and the board is really draw heavy so I would include hands like AJ or QQ into his range for raising here.

hating life cause your 150bb w/ the 17-9. if it was 100bb I'd just ship it as played but I think that's probably spew now.

Not betting this flop seems really really bad. Every range connects with JTx two-tone, almost every hand has a pair or draw on this board, you get called by so many worse hands. Now we're lost and probably have to fold the best hand a lot.
