Time-pressure in chess: definition & tips
Time-pressure (also called “time trouble” or the German loan-word “Zeitnot”)
Definition
Time-pressure is the situation in which a player has exhausted most of the allotted thinking time on the game clock and must play the remaining moves of a time control with very little time, often seconds, remaining. It is commonly measured against a formal threshold such as “under five minutes with no increment” or “fewer than 30 seconds per move on a 30-second increment.” In classical chess score sheets and commentary you will often see the abbreviation “(?)” or “??” attached to a move played in severe time-pressure, indicating that the blunder was at least partially caused by the clock.
How It Arises
Time-pressure can occur for many reasons:
- Spending too long in the opening to recall preparation
- Calculating a critical tactical line in the middlegame
- Struggling to find a plan in a strategically complex position
- Nervousness or lack of experience with a particular time control
- Poor time management habits—e.g., moving quickly in quiet positions and slowly in forced ones, instead of the reverse
Strategic Significance
Playing in time-pressure drastically changes the strategic landscape:
- Mistake rate increases; players value practical rather than objective soundness.
- Simplification (exchanges) becomes attractive because it reduces calculation.
- Sharp tactical complications can be deliberately introduced to exploit an opponent’s clock shortage.
- Increment and delay mechanisms (e.g., 30 s increment or 5 s delay) mitigate but do not eliminate the phenomenon.
- In sudden-death controls, flagging (winning on time) becomes a legitimate winning method, especially in online blitz and bullet.
Historical Perspective
Before digital clocks, analog clocks had flag falls; the small metal “flag” literally fell when a player ran out of time. In pre-increment days, grandmasters would sometimes reach move 40 with only seconds left, scribbling moves on the score sheet after the time control to save precious seconds. The term “Zeitnot” was popularized in German commentary and adopted worldwide.
Famous time-pressure addicts include David Bronstein (who once confessed he “liked the excitement of playing with the clock more than the pieces”) and Viktor Kortchnoi, who routinely entered Zeitnot yet produced near-miraculous defensive resources.
Illustrative Example
In Kasparov – Ivanchuk, Linares 1991, Kasparov built a large positional advantage but spent enormous time calculating a sacrificial breakthrough. Ivanchuk, in acute time-pressure himself, overlooked defensive resources and blundered on move 38, just two moves short of the first time control:
[[Pgn|1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 e6 7. f4 Qb6 8. Qd2 Qxb2 9. Rb1 Qa3 10. e5 dxe5 11. fxe5 Nfd7 12. Ne4 Qxa2 13. Rd1 Qd5 14. Qe3 Qxe5 15. Be2 Bc5 16. O-O Nc6 17.

Rd4+ |fen|r1b1kb1r/pp1n1ppn/3p4/q1p1pP1p/5P2/3P1N2/PPPQ2PP/2KRBBNR b kq - 0 0]]After Kasparov’s 39.Rd4+, Black’s pieces were pinned and the game collapsed quickly. Commentators noted that both players were down to seconds, and the move 38…Kd7?? would almost certainly not have appeared on the board with a comfortable clock.
Interesting Facts & Anecdotes
- The infamous “40th-move blunder” trope (e.g., Kramnik’s 40…Qxe3?? vs. Topalov, Wijk aan Zee 1999) owes its existence to players rushing to beat the first time control.
- Magnus Carlsen is celebrated for squeezing opponents in equal endgames and keeping more time on the clock, effectively “doubling the match clock” because the opponent must defend accurately while low on time.
- In online bullet (1 + 0), flagging strategy has evolved into premoving tours de force; elite bullet players can produce 250–300 half-moves per minute.
- Some analog clocks had a smaller red flag for the second time control (e.g., move 60) leading spectators to watch two different flags in a single game.
Practical Tips for Handling Time-pressure
- Adopt a time budget: e.g., 50 % of your base time for the first 20 moves.
- Use opponent’s time to calculate candidate moves, write down move number, or update your score sheet.
- Favor plans that limit calculation—simplify when objectively safe.
- Practice with shorter time controls (rapid, blitz) to improve intuition.
- If increments exist, train to play tempo-safe moves within the increment so you can rebuild a few seconds per move.
In a Sentence
“After spending 40 minutes deciding on 22…♝f5, she was in severe time-pressure and eventually blundered the exchange on move 38.”
