Gambling and games of chance are a curse, even if to some small degree they are necessary. Gambling impoverishes families; it destroys marriages and therefore corrupts children. Unfortunately, no matter how many times you tell gamblers that they can’t win, they keep on gambling until they have lost all. We know they can’t win because professional gamblers use every means possible, both legal and illegal, to shorten their odds and win; they count cards, they mark cards, they use mathematical formulae to find the errors of the race track handicapper.
