Cheating is an act of lying, deception, fraud, trickery, imposture, or imposition. Cheating characteristically is employed to create an unfair advantage, usually in one's own interest, and often at the expense of others. Cheating implies the breaking of rules. The term "cheating" is less applicable to the breaking of laws, as illegal activities are referred to by specific legal terminology such as fraud or corruption. Cheating is a primordial economic act: getting more for less, often used when referring to marital infidelity.
Another venue where cheating has occurred is in sport. An implicit agreement exists among participants that they will play by the rules and eschew unfair measures to win. Cheaters violate the spirit and/or the letter of the rules of competition. Examples include Ben Johnson's disqualification for doping in the 1988 Summer Olympics or the admissions of steroid use by former professional baseball players after they have retired, such as José Canseco and Ken Caminiti.
Cheating refers to more than using illegal substances. Perhaps the most famous example of cheating in professional sport took place in the 1986 FIFA World Cup when Diego Maradona used his hand to punch the ball into the back of the net past the England goalkeeper Peter Shilton. Using the hand or arm by anyone other than a goalkeeper is illegal according to the rules of association football.
Another example of cheating frequently seen in sports is the use of non-regulation (vis-a-vis the rules) equipment. In baseball, a pitcher using a doctored baseball (e.g. putting graphite or Vaseline on the baseball, or a batter using a corked bat are some examples of this.
