Tactic
A tactic is a short, forcing sequence of moves that exploits a concrete feature of the position, such as a fork, pin or unprotected piece, to win material, deliver mate or reach a clear gain.
A tactic is a calculable trick: a few forcing moves that change the position in your favor because of something concrete on the board. Checks, captures and threats dominate, since forcing moves leave the opponent few replies and make the line easy to verify.
Tactics differ from strategy in how they are judged. A strategic plan is slow and rewarded over many moves. A tactic either works or fails, usually within a handful of moves. A single missed tactic can decide a game at any level, so the skill pays off from a first tournament to master play.
To find tactics, look for the ingredients. Loose pieces, kings with few escape squares, pieces lined up on a file or diagonal, and overloaded defenders all signal that something may work. Then check forcing moves in order: checks first, then captures, then threats. Calculate each line to the end before playing it.
To defend, ask before each move what forcing replies your opponent has.
Hunting for a combination in a position that does not contain one wastes time and energy. Tactics grow out of the position. Without a weakness to exploit, the right move is usually a sound improving one.
Also worth reading is Tactics training. Tactics training is deliberate practice at spotting and calculating short forcing sequences, such as forks, pins and mating attacks, usually through puzzles, so that these opportunities are found quickly in real games.
Compare it with Tactical motif. A tactical motif is a recurring pattern, such as a fork, pin or skewer, that appears often enough in games to be recognized and reused as the basis of a combination.
Also worth reading is Counterattack. A counterattack is a reply to a threat that answers it with a threat of your own instead of defending, usually a larger one, so the opponent has to deal with yours first.
To see how often "Tactic" or a pattern like it decides your own games, book a first lesson: George Li reviews your games and writes a study plan around what he finds.

A tactical motif is a recurring pattern, such as a fork, pin or skewer, that appears often enough in games to be recognized and reused as the basis of a combination.
A combination is a forcing sequence of moves, usually built from sacrifices and checks, in which every move leaves the opponent few or no choices and the sequence ends in a concrete gain such as mate or material.
A sacrifice is a deliberate decision to give up material, such as a pawn, an exchange or a piece, in return for something else, like mate, a stronger attack, a better structure or a larger gain later.
Tactics training is deliberate practice at spotting and calculating short forcing sequences, such as forks, pins and mating attacks, usually through puzzles, so that these opportunities are found quickly in real games.
Calculation is the skill of mentally working out concrete sequences of moves and replies, one line at a time, to judge what a position really offers before committing to a move.
Pattern recognition is the ability to see familiar arrangements of pieces and pawns, such as tactical motifs and typical structures, and to recall what they usually mean without calculating from scratch.
