CO has been quite aggressive, and I expected him to c-bet, hence the look to check/raise. No read on BB.

Should I have reraised preflop?
Should I have led out on the flop?
How about the check/call on the river?

Prefloop is good.

I really prefer a bet on the flop because of those KhQh but crai intention is good with your read on CO.

I don't see a reason to bet the turn into 4 oppponents after both JT and the flusher have hit. I check and try to have a cheap showdown.

As played, folding the river seems better. What do you beat, really ? AJ and ?

I take the risk and shove the flop
check/fold turn and river
