KTs is a lot like JTs

[Goodnews]

does CO raise for free cards? does he bets his draws (regardless if he has equity or not)?

3bet is sweet on the flop, turn is standard, I would check/raise the river since u say CO is aggressive, he might try to bluff a busted draw and also bet a weaker king. Its been a while since I last played limit, but I don't think you want an overcaller in this spot, so you might push off the BB.
