Ooops wrong title! Big hand w/ decision on turn.

I think I may have misplayed this hand on every street.

CO is a aggro fish, whose down 4 BIs. His stats are 78/72/77.8/11.0 over 33 hands.

MP seems like a solid player and we've tangled before in a pretty big pot where I missed a v-bet on rvr with flopped FH that became 3rd nut on rvr. I'm up 1.5 BI's on him, when this hand comes up. His stats are 32/15/5.0/2.1 over 75 hands.

Should I be iso'ing against the fish pre-flop with this hand OOP?

I hit my flop, and am looking to c/r against the PF 3-bettor. His C-bet is 40% in 3-bet-pots, which I didn't see at the time. Since he doesn't have a real high c-bet % and it's multi-way would this favor a donk bet.

Now that my hand has gotten ridiculous on the turn, what's the play? Does the possible straight on the board worry us at all, or are we betting turn for value here? How much?

I would bet the flop and get it in. When we have a flop crushed is when some card that makes a straight that is not ours hits the turn.

Without running equities against possible straight, I would imagine we are 39-41% on the turn.

I think you will get a lot of folds on the flop if you lead, which is OK, but you are in really good shape against most anything villian holds, so you will be happy to stack off.

It is just unlikely that you are up against a set.

b/c turn. on flop leading and c/r are both fine imo. I'd be more likely to lead if there was a flush draw out that we dont have.
