When I was around 18 and a C player in our pool hall I used to play a class A player who spotted me 25 points to a game of 50 in straight pool and always beat me.One day I said that I would play him even.He said I was nuts because I could not even beat him with the spot.I took no spot .He said that he would break and I said we will lag.He lost the lag,broke and I ran 25 on him.Never ran that many ever!! Beat him like 50-38.I would get too comfortable with that big spot.Go figure.
