No reads on villain. With the action that exploded right infront of me preflop was it realistic to fold the kings? After the flop I felt committed to try for the spade making me the nuts but missed. On the river I felt like there was too great a chance he had raised with Jacks or Queens to fold based on the pot size. (even though I realize that that chance was small)
Will post results if needed. Whether or not folding the kings preflop or not is feasible is my main question.
