You dont say whether u have the Ks… is very important info. Overall I think it is a reasonable fold…tough spot.. but reasonable fold nonetheless less. I would probably call turn and fold to any to action on the river with no Ks in hand. Having the Ks would make it very interesting on river if 4th card flush came in.. but not sure what the right play is.
Have you plugged in ranges and calculated equity of you cards against their ranges? I plan to do it on my end but if you have already please share.
