If you're going to c/r, it's better to do it on the flop than the turn.
He shows up with a bigger sets very often when he bets into 3 twice, and then shoves over a turn c/r.

I don't think leading is bad at all. It's tough to get the money in good 4-way this deep, so check-raising is kind of marginal, but check-calling is a little weak as well.

+1 on lead....you shouldnt forget that these kind of boards often get checked through even this multiway and beside an A or 2-5 that isnt a club about any card will complete a draw and will give you headache or kill the action. As Chael said XR is marginal therefore we´re so deep and XC might price a lot of marginal draws in...We can easly donk/c and XC any turn...we barely get 3barrel bluffed OTR after that line and have easier decisions.....

donk/c was meant to say we donk-get raised-and call so that we would X to the flopraiser OTT...hm...not sure about donk/f cauz there is a lot of combodraws that might just want to add some FE...hm...need to construct a range tomorrow and check if we get enough equity on a call....could be potentially a donk/f....

I dont see how this hand could be played out any other way other than a C/R flop, and Jam turn.

Reasons: 1) The board is extremely Wet with both FD+SD

2) We hit the Top of our hand range

3) We're 150BB effective in the pot, and we have another Villain with 100BB stacks. Getting the money in 150BB with a Set is definitely a reasonable justification.

4)We're first to act in the hand. Likely scenario:

We Check, BB Bets $2.25, UTG, CO calls. 

so there's Extra $6.75=(27BB) Dead money added to pot, which gives us extra incentive to C/R flop for value+equity protection multiway.

Pot:$9.75=39BB  

with 39BB dead money already in pot, i dont see how we dont C/R to try and take down the pot.

I prefer donkbet here. First because it would be a disaster if everyone check with so much cards that kill our action turn (clubs, Q, J, 8, 7). And in a second hand because I'm gonna be more comfortable donking as a semi-bluff than c/r.

But I agree that if you check the flop it's for c/r, c/c is the worst option.

we need between 41% (vs UTG) and 44% equity (HU vs anybody else) to just shove OTF after checking. Vs sets, nuts and combodraws we get about 32% equity...only if we add every NFD that will go broke we will become about 43% equity...i mean we´re not just jamming flop so these numbers shouldnt matter too much for our flop decision but theyé makin me a kind of suspicious if gii here is really the right play.....

This is getting an interesting discussion :)

I can see now I took probably the worst option on the flop by check/calling and waiting for a safe turn card. Now I was just lucky to catch one of the few good turn cards and get it in vs T8o, even though I won the hand I wasn't sure that I played it correctly.

But I'm still not really sure if we want to c/r here or donkbet. The upside of a c/r like TheLove_Below said is that we are going to scoop a lot of dead money a good percentage of the time, the downside however is that when someone reraises or shoves we're commited and I'm not getting it in very happy in this spot.

If we donkbet and just get called we can be pretty sure that we have the best hand at that point and bet big on most turns and potentially get it in, if our donkbet gets raised I think its a fold, like I said before I don't think these villains raise with a worse hand than ours. 

So I'm leaning towards a donkbet now, I expect villains to play very fit or fold when I lead big into them in a 4-way pot so I'm getting a pretty clear picture to see if we're beat or not and still get a lot of value. A c/r however feels a bit more like "jamming in the dark"
