Villain is 25/10/2.5, not particularly aggro, over 300ish hands. I am attempting to rep AK, KK or KQ, all of which would be within my UTG raising range (KQ pretty marginal but the table was very passive).

Comments on the river donk and any on previous streets would be much appreciated. (e.g. do others continue to lead the turn? if so, what if raised?)

hmmm, both of you having a king is reasonable. Seems marginal but okay.
