I would check-call the turn with your J high flush draw as well as a pair which will be good a decent amount of the time. He has limp-called so his range his likely fairly wide and less likely to contain stronger hands since he is 21/15 so does raise a decent portion of his range pre-flop.

River may be a good spot to bluff vs regs if they know you are capable of playing a flush like this, but against a likely weaker player i think its the worst of the 3 options.

I think Call>Fold>Bluff-raise. Although i could be convinced that a fold is better than a call.

what about a flop cbet ? I just dont see what value hand you are checking on a flop like this so x/c seems like telling your opponent that you have medium strenght hand.

I'd cbet this flop with 2nd pair+, FDs, SDs, TP and some high card with bdfd and 2nd barel with flushes (value), SDs and turned FDs. I'd check turn with the rest of my range..

ty guys!
Maybe river fold>bluff-raise>call

i would just flat river.

i rather bet flop and ck/c turn and evaluate the river
