The clock sometimes reveals a problem that position analysis alone does not explain. You had found a good candidate, but repeated its calculation until too little time remained for the rest of the game.

Managing the clock means deciding what deserves another minute. A practical rule can help; no fixed allocation replaces examining the position and time control.

What the data can tell us

Guid and Bratko (2006) compare world champions’ moves with Crafty’s evaluations. They examine, among other things, position difficulty and the limits of that comparison. Their article does not provide the statistic that time trouble causes 30% of tournament losses.

A computer evaluation and a player’s thinking time are different variables. You cannot infer causation from an association between a lengthy decision and an error alone: a difficult position may produce both.

Spending time for an identifiable reason

Before a long think, try naming what needs resolving. A forcing combination? A choice between two endgames? A threat you cannot find a way to meet? This helps you recognise when calculation is still adding something.

Compare several candidates when the position calls for it. There is no need to invent five if only one move prevents mate. Conversely, do not spend all your time on the first attractive sacrifice without examining a simpler continuation.

If you recalculate a line, ask what justifies checking it again. A precise doubt deserves resolution; restarting without a new question can become a costly habit.

A reserve rather than a rigid split

Dividing time into thirds can serve as a reminder, but neither phase length nor difficulty is fixed. A tactical problem may arise in the opening. An endgame may demand much more thought than the middlegame.

Before playing, check the starting time, increment and any time controls. Then build a reserve suited to that format. A rule designed for ninety minutes does not transfer mechanically to a rapid game.

Critical moves may deserve more time than obvious ones. No universal multiplier of three, ten or fifteen is established here.

In time trouble

Keep a minimal check: is your king threatened? Is a piece hanging? What was the opponent’s last move? You can reduce the ambition of your calculation without ceasing to examine forcing replies.

Simplifying may make the rest easier, but an exchange can also worsen your position or lead to a difficult endgame. “Exchange because time is short” is therefore not a sufficient rule.

Do not automatically copy your opponent’s rhythm. A fast reply may come from preparation, a forced decision, intuition or a mistake. The clock gives a clue; it does not reveal what the other player thought.

Analysing the minutes spent too

After the game, identify a few moments when you thought for a long time. What were you looking for? What did you actually find? Had you spotted an important defence or simply delayed choosing?

Compare several games at the same time control. One episode is not enough to classify you as impulsive or perfectionistic. This record can, however, reveal a specific difficulty to work on in your game analysis.
