Blitz is defined by total thinking time rather than by feel. Under FIDE rules a game is blitz when each player's base time plus the increment multiplied by sixty falls at or below ten minutes — which is why 5+0 and 3+2 are both blitz, and why 5+3 sits at the boundary. Below the blitz threshold the game becomes bullet; above it, rapid.

Five minutes with no increment is the classic blitz control and remains the most played. Three minutes plus a two-second increment is the modern online default, and the two produce different games: 5+0 rewards banking time early, 3+2 rewards playing quickly throughout because every move earns time back.

Increment changes the game more than base time

A two-second increment removes the endgame scramble in which a winning position is lost to the clock. That single change alters what blitz rewards: with an increment, technique in a simplified endgame is worth playing out; without one, it often is not.

Players who dislike 5+0 usually dislike being flagged in won positions. Players who dislike 3+2 usually dislike that a lost position can be defended almost indefinitely by moving fast. Both complaints are accurate descriptions of the format.

The boundaries are worth knowing

The calculation FIDE uses — base time plus sixty times the increment — is what places a time control into bullet, blitz or rapid. It matters for tournaments, where the rating pool and sometimes the rules on illegal moves differ by category.

For casual play it is trivia. For anyone entering a rated event, it decides which rating the result affects, and it is worth checking rather than assuming.

Handling the clock is a skill

Pressing the clock with the same hand that moved the piece is the rule, and forgetting to press at all is a self-inflicted loss that happens to everyone at least once.

The other durable habit is glancing at the opponent's remaining time, not only your own. Knowing that they have forty seconds and you have ninety changes which position you should steer toward.

Where common controls fall under the FIDE calculation of base time plus sixty times the increment. Verify current regulations for a rated event.

Time control categories
Control	Calculation	Category	Character
1+0	1 min	Bullet	Reflex and premoves
2+1	3 min	Bullet	Increment softens scrambles
3+0	3 min	Blitz	Fast, flag-heavy
3+2	5 min	Blitz	Modern online default
5+0	5 min	Blitz	The classic control
5+3	8 min	Blitz	Near the rapid boundary
10+0	10 min	Blitz (at limit)	Boundary case
15+10	25 min	Rapid	Real thinking time

The category decides which rating pool a rated game affects and can change rules on illegal moves.
Press the clock with the hand that moved the piece. Forgetting to press is a loss nobody escapes forever.

❓ Frequently Asked Questions

What counts as blitz chess?

Under FIDE rules, a control where base time plus sixty times the increment is at or below ten minutes — so 5+0 and 3+2 are both blitz. Below that range is bullet; above it is rapid.

Is 5+0 or 3+2 better?

They are different games. 5+0 rewards banking time early and produces endgame scrambles; 3+2 rewards moving quickly throughout because every move earns time back, and largely removes flagging in won positions.

Why does a small increment matter so much?

Because it changes what the format rewards. With an increment, technique in a simplified endgame is worth playing out. Without one, a winning position can simply be lost to the clock.

Does the category affect my rating?

In rated play, yes — the category determines which rating pool the result affects, and can change the rules applied to illegal moves. Worth checking before an event rather than assuming.

Which hand do I press the clock with?

The same hand that moved the piece. It is a rule rather than a convention, and forgetting to press the clock at all is a self-inflicted loss that happens to every player eventually.

Should I watch my opponent's clock?

Yes, and most players do it too little. Knowing they have forty seconds while you have ninety should change which positions you steer toward — complexity favours whoever has time to handle it.
