Open raised, SB call and on flop villain pot. I have 6 outs so 14% equity on turn is not enough but we have lot behind and any pairing card is close to nuts. Villain should have mainly flushes here so any Kx two pair should be rare. So pot should be get into 2.3€ to make flop call ok. Well I suppose its questionable to be honest.
On turn I have 9 outs and villain size it smaller so more clear call with having still lot behind.
River was Ks and villain minbet. What sort of sizing would you raise?
). the flop call is player-dependant, if he is straightforward you should fold as you have no implieds. a pot-sized bet also signals primarily strong flushes (especially nutflush), if he is bluffing, we are more likely to make money as our hand works as a bluffcatcher, so it is useful to know how often he is bluffing. You also risk an under-dog scenario against 
:Kx:xx overfulls so be carefully. But to me this tables and the pre-call from sb do not look solid so calling may be good.
