Chess clock guides
19 straight answers about chess clocks, time controls and the rules that decide games on time — each one ending with the clock set up and ready.
Getting started
How to use a chess clock
Who presses first, which hand to use, when to press, and what happens when a flag falls. The whole thing, once, properly.
Read itHow to set a chess clock
Digital, analog and app. What to set, in what order, and why every brand hides it behind a different mode number.
Read itWhy is my clock counting up?
Almost always the wrong mode — but sometimes it is increment doing exactly what it should. A diagnostic table.
Read itTime controls
Chess time controls explained
3+2, G/30 d5, 40/90 SD/30. Every notation you will meet, decoded, with a table of what each one feels like to play.
Read itWhat is increment in chess?
Seconds added every move, why Fischer proposed it, and the arithmetic that lets a fast player finish with more time than they started.
Read itDelay vs increment
One adds time you keep, the other only protects what you have. Three systems compared, with the arithmetic for a ten-second think.
Read itWhat is Bronstein delay?
Your clock falls, then gives back what the move cost you. Why it exists, and why it ends up identical to simple delay.
Read itWhat does 3+2 mean?
Three minutes plus two seconds a move — and a table decoding every other control written the same way.
Read itWhat does 15|10 mean?
FIDE's standard rapid control, what it costs an organiser in round length, and how it compares to 10+5.
Read itRules
Running out of time
You usually lose — but not always, and the flag has to be claimed. What the rules actually say.
Read itTimeout vs insufficient material
Your opponent flagged but you only have a bare king. Win or draw? FIDE and US Chess genuinely answer this differently.
Read itChess clock rules
Move then press, same hand, no hovering, and what an arbiter will actually do about it. The rules that decide games.
Read itWhich hand presses the clock?
The same one you moved with — and it is a real rule, not etiquette. Why it exists and what happens if you break it.
Read itWhich side does the clock go on?
Black's right, by convention — and the arbiter's call in a FIDE event. Plus where a phone goes instead.
Read itChoosing a control
Blitz vs rapid vs classical
Where the boundaries actually are, why FIDE measures total time rather than base time, and where bullet fits.
Read itFIDE time controls
The official classical, rapid and blitz controls, the formula FIDE uses to classify an event, and how to run them on a clock.
Read itHow long does a game take?
The ceiling for any control is (base + increment × moves) × 2. A table of real numbers, and what to budget per round.
Read itThe best control for beginners
A real recommendation rather than a shrug, with a progression from a first clock game to a club night.
Read itUsing a clock with kids
When to introduce one, which control to start with, and how to handle the first time a child loses on time in a winning position.
