1/2 - where´s max value?

UTG is a donk, CO somewhat taggy. I´m indifferent between donking out and check raising. A CR will likely blow out a lot of UTG´s range, with which we prolly calls two bets on two streets, donking out will look ridicilously strong to CO, who may cbet quite a lot vs a donk and my perceived {22-88, random sc´s}. C/c doesn´t look too sexy, I´d really hate to see a spade killing my action.

Donk bet for sure.
C/R is better if UTG was PFRer and CO was donk.

Lead, hope to get raised then make a really fucking big re-raise.

I don't mind a check-call here. This line helps keep the bad player in the pot, and doesn't miss too much value from cutoff since he will often by isolating the fish with a marginal hand and so won't have much with which to pay you off if you check-raise.
