Top two here is pretty strong; however a set would leave me more outs if he already has a flush. I realize that if I continue here on forth street the rest of the chips are likely to go in. I ended up calling here then my opponent went all in on the river after an off-suit 4 paired the board. I called, he rolled over KQ off with the king of spades he must have been trying to maximize fold equity with his 2nd-nut draw to the four flush that bricked. So in hind sight I won the hand, but at this decision point to his turn raise, is this a more profitable call or fold? Thank you!
