Pattern recognition
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.
Also called: patterns
Strong players do not examine every position afresh. They recognize it: this looks like a known mating pattern, that structure usually leads to a pawn break on the queenside. Recognition saves time and points the calculation in the right direction.
Patterns come in several kinds. Tactical ones include forks, pins and standard mating shapes. Positional ones include typical pawn structures, outposts and the plans that go with them. Endgame ones include known drawing and winning positions. All of them are built the same way: seeing many examples until the shape sticks.
The danger is over-trusting a pattern. A position can look like a familiar one while a small difference changes the result, so recognition should lead to a check by calculation, not replace it. Another trap is learning patterns by memory of names without ever seeing them in real games.
To build the skill, study model games and annotated examples, repeat themed puzzle sets, and replay your own games to find patterns you missed. Keep a short list of shapes that keep appearing in your play, and review it from time to time so it stays fresh.
Also worth reading is Puzzle theme. A puzzle theme is a label for the tactical idea a puzzle teaches, such as a fork, a pin or a back rank mate, so that training can be grouped by pattern and weaknesses can be targeted directly.
Also worth reading is Spaced repetition. Spaced repetition is a study method that revisits material at growing intervals, such as tactics, opening lines or endgame positions, so that knowledge moves into long-term memory instead of fading after one session.
It sits close to 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.
Training ideas such as "Pattern recognition" work best with a plan built for you, and the first lesson with George Li produces one from your own games.

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 mating net is a setup in which the enemy king is surrounded by attackers and its own pieces so tightly that checkmate cannot be avoided, even if the final blow is a move or two away.
Isolated queen's pawn structure
A structure in which one side has a pawn on d4 (or d5) with no friendly pawns on the c- or e-files, giving active pieces and attacking chances but a long-term weakness in endgames.
