In chess, the term ‘sharp’ is used to denote a move, position, game, or style of play that involves highly tactical positions in which there is the potential for great reward and little or no room for error. The term may also refer to a player who regularly plays in such a manner. A sharp position frequently contains a significant amount of asymmetry, meaning that the position has differing goals for each player. Players may use sharp moves in order to take an opponent out of his or her comfort zone and see if this can produce a mistake that one can use to win the game. But this can also backfire; a mistake on one’s own part can lose the game in such positions. The essence of sharp play is to play aggressively, making threats and responding to threats with counter-threats rather than with passive or retreating moves. Common advice to novice players is to practice playing sharp lines, but doing this in tournaments or against stronger players is likely to produce defeats, as one is likely to make a mistake. It is more effective to be a sharp player than to try to find sharp moves here and there.

An analogy may be drawn with a particular style of argumentation. Sharp argumentation aims to step outside the Overton window in order to take an arguer out of their comfort zone and make them defend ideas that they assumed were universally accepted. The goals are different for each participant in sharp argumentation, in that the mainstream commentator is trying to defend the range of allowable opinion while the sharp arguer is trying to challenge and move it in their direction. This tactic has the high risk of making one look foolish if one cannot defend such a position with great skill, and it has the high reward of making an opponent look foolish if they cannot attack the position well. The goal of a debater should not be to seek out particular sharp positions just to troll and trifle with one’s opponents, but to become sharper in a more general sense.

Accepting Absurdity

With the nature of sharp argumentation established, let us now consider a situation in which one might use this tactic. Consider a libertarian who supports the right to keep and bear arms and is going to debate with a progressive who supports greater gun control measures. The progressive says, “The right to keep and bear arms is not absolute. For example, no one thinks private citizens should have nuclear weapons. There are reasonable restrictions that we can all agree upon.” The goal of the progressive here is to define a certain position as out of bounds while stealthily taking ground.
