Common situation with specific hand

[jesse8888]

Common situation:

I'm in horrible to bad position in a 4 to 7 way flop with two broadway cards. The flop is paired under my hole cards, and the third card matches one of my cards. Assuming it wasn't raised pre-flop and hence the pot is "smallish", how do I proceed? What factors are most important? Obviously the rank of the pair in the flop matters a lot, but what else should I be thinking about?

Specific Hand, 6/12 live

Hero is UTG with KJ clubs. Hero limps. We end up 7 handed including both blinds (one guy was walking and somehow UTG+2 folded his hand). Flop comes:

TTK (one club but rainbow).

Blinds check, hero donks, UTG+1 calls, CO calls, BB calls. Turn is:

TTK7 (now rainbow complete)

What do I do here? 3 callers on the last round smells pretty darn fishy to me, but it seems like I have to venture a bet. These guys will play LOTS of kings (suited and otherwise) and I could easily be up against a week king, a straight draw and....like pocket 4s or something.

Is it bet/fold? bet/call? check/call? What about the flop donk? Is that standard, or should I be trying to checkraise?
