i'm kind of still in the early stages of learning poker and not sure exactly what Harrington means in his volume 1 book on page 124 where he says and i will quote, "To be more precise in your calculation multiply the size of your intended bet by the probability he will call it." Is there a number that represents the probabiity he will call it? if someone could, plz explain it as simple as you can if you can, if you can't just explain it the way you can. thanks everyone!
