Again, I guess my play is okay till the river. I raise on the river for value - does this make sense given pre flop action and subsequent streets?
I can't put anyone on a club flush draw. Really hard to know what villians hold except for lower pps hoping they're somehow good at showdown, maybe JJ. AJ possible looking at gutshot to nut straight which isn't unusual. Should I play scared here that the CO has me beat with AA, KK, AQ, or QQs and has just slowplayed the whole hand post flop to the river? And if so, would that be optimal play in this situation given my continued inflating of the pot with only TPTK and a couple of callers?
Thanks again for any assistance.
