Concentration
Concentration is the ability to keep your attention on the current position, the opponent's ideas and your own calculation for the whole game without drifting into distraction, hope or worry.
Also called: focus
Chess punishes lapses of attention more than almost any other game, because a single unnoticed threat can undo hours of good play. Concentration is what lets you actually see the board as it is, rather than as you expect it to be after the opponent's last move.
Players usually lose focus in predictable moments: after winning material and relaxing, when a position is long and quiet, when the clock is low, or when worry about the result crowds out thinking. Another frequent problem is wandering between ideas without finishing any one calculation.
A practical habit is to run the same short check before every move. Ask what changed, what the opponent now threatens, and whether your intended move leaves anything loose. A fixed routine gives the mind something concrete to do, which is easier than simply trying harder to focus.
Train it away from games too. Solve puzzles without moving the pieces, play long classical games with phones out of reach, and notice when your mind has wandered. Sleep, food and water before a round matter more than most players admit, since tired minds miss simple tactics.
Compare it with Blunder check habit. A blunder check habit is a short, fixed routine run before every move, asking what the opponent threatens and whether the intended move leaves anything undefended, to catch one-move oversights.
Compare it with Chess psychology. Chess psychology covers the mental side of the game, including focus, confidence, nerves, emotion after mistakes and the habits of mind that help a player perform close to their true strength.
Also worth reading is Time management. Time management in chess is the skill of spending clock time where it matters most, thinking longer in critical positions and moving quickly in routine ones, so that you never face a decisive position with seconds left.
Habits like "Concentration" stick when someone checks them against your games. A first lesson with George Li ends in a written plan and homework for the weeks after.
