You pretty much have the deck crippled (by the turn) so you want get much play from opps with any bet you make. (Anyone with a King or 88 will definately let you know by the turn.) Now since the queen clubs hit on turn and crippled the deck, you could wait until the river. I think anything other than a large bet is probably ok. Checking: ok, since you arent hurt on a river card. Small bet: ok, maybe someone with AQ, AA, Kx, JJ, might think they have the better hand or flush draws would still pay to see the river. Big Bet: Scares out the flush draw, med pairs, etc. Only opps that might play are 88, Kx, AQ, Qxc(clubs). However, if they had those cards, they probably would re-raise a small bet and probably give you the same amount of play.

Maybe if the flop was AKx and you held KK, you could start immediately firing away and bet.
