In the game of chess, prophylaxis (Greek προφύλαξις, “prophylaxis,” guarding or preventing beforehand) or a prophylactic move is a move that stops the opponent from taking action in a certain area for fear of some type of reprisal.

What are Prophylactic moves in a chess game?
Prophylactic moves are aimed at not just improving one’s position, but preventing the opponent from improving their own. Perhaps the most common prophylactic idea is the advance of the rook pawn near a castled king to make luft averting the possibility of a back rank checkmate, or to prevent pins.
Why do players play in the prophylactic style?
Players who play in the prophylactic style prevent the initiation of tactical play by threatening unpleasant consequences. One of the largest advantages of this approach is that it keeps risk to a minimum while causing an overaggressive opponent to lose patience and make a mistake.
When to play h6 or A6 in chess?
Pawn moves such as h6 or a6 don’t require such an immediate threat in order to be played. They can often be played as recreational moves to stop tactics of bishops or knights occupying the g5/b5 squares entirely.
What’s the difference between prophylaxis and tactical play?
In a more strategic sense, prophylaxis leads to a very positional game, often frustrating for players with a strong tactical orientation. Players who play in the prophylactic style prevent the initiation of tactical play by threatening unpleasant consequences.
