First off, wow, I need to find tables like that more often.

I'm not sure about the preflop call. But with three cold calling the raise, I probably complete.

I probably lead out the flop. I would probably check/raise if UTG+1 bet and it came back to me, but I just call when it comes back for 2. 3-betting won't knock anyone out, only BB would have to think about it.

Turn is fine given the flop.

River donk is fun, since it keeps AK/AQ type hands from checking and CO is going to check this river. If you get raised, well, you're probably done for, but it's an okay call.
