Kinda funny story: I had just finished “Reasses Your Chess” by Jeremy Silman [sadly forgot most of the lessons after all this time], and was playing a kickass game on FICS and the guy who I was playing accused me of using a computer chess program. 
Funny thing, but if the guy had looked at my history, he’d have noticed I don’t win all my games, and depending on my mood, sometimes I win against higher level players, and sometimes I lose against lower level players. Of course against players close to my level, its about 50/50.
