Think about how stupid the average person is, and then realize that half the word is stupider than that.
I'm always amused by this cliché...because it actually turns out to be false.
Lets say I have 9 people who are 2 feet tall and 1 person is 12 feet tall. The average height is 3 feet. but 9/10ths of the group are shorter than average.
Not at all sound, but few players will be able to resist Qa4+?
