NL25 99 on board wet - 4way - bet,bet,x/?

I think I would check/call turn instead of bet.
As played I think it is better to check fold OTR or then make a small block bet yourself.

Our 99 is not a monster 4-ways. Already bluffing (ridiculously small) with it once may be overdoing it. Move on to the next hand without investing much here. (If CO bluffs you out, then so be it.)

Our hand is not worth 3 streets here.
You can call once in a while though.

I totally disagree with putting any money into this pot. It's 4way and the chances we are outflopped are very high + we barely have equity with our two-outer to continue. Betting 1/3 pot on the flop looks like a good option to protect our hand and take the pot down, but I would rather do it 3way. With another player involved it's too thin I guess. No shame to give up pots like these, and I mean right away, on the flop.

Flop : C-bet ou x/call dans 4way ?
- Answered this one above

Turn: standard
- Why standard, can you explain? What is your reasoning for betting? Do you expect him to call worse? For the deadmoney? I don't think it's standard to cbet the turn

River: ?
- People are not bluffing enough on the river. And you block stuff like 89s and T9s which makes it even easier of a fold.

I would probably check/fold the flop 4-way, but not sure if that would be the best play. Cbetting 1/3 looks fine, though, but I would give up the turn then.

One and done
