you are heads up on the river in NL hold'em. You put your opponent on the draw for a flush. He thinks he has 9 outs.
But you hold 1 card in his flush suit. So he really only has 8 outs. I understand 9 outs is 19.6%, and 8 is a 17.4%.
How would you adjust bet sizing to best take advantage of the differnce. Or is it actually not significant enough?
Well I can see you would price it about 2% higher. I, still a novice, really want to know if this is actually useful in practice.
