Didn't realize flop was 3 handed at first either.
PF 3 betting is an option and is in my range vs certain vils. Ya getting 4 bet sucks. But against regs i think there is still a ton of value to be had in 3 bet pots since people give less and less credit these days.
As played my default would be to C/C flop and go from there.
River I see your thinking in betting a little bigger to rep missed Club draws. Sounds like hes a thinking player but for him to call with worse seems to be a history dependent play. C/C is prob what Id do.
