Same Game, Different Competitive Procedure
Standard, rapid and blitz use the same legal chess moves, but time pressure and supervision change what can realistically be recorded, observed and corrected. The format therefore matters whenever you discuss illegal moves, flag fall, scoresheets or arbiter intervention.
Under the current FIDE Laws, rapid is classified using the player's total time for a 60-move game as more than 10 and less than 60 minutes; blitz is 10 minutes or less. Full-supervision and reduced-supervision regimes can then change the procedure. Do not import a blitz shortcut into standard chess or an old rapid rule into a current event.
Standard, rapid and blitz share the same chess game but can differ procedurally because supervision and time pressure change what can realistically be enforced.
Core rule Never import a blitz shortcut into standard chess—or an old rapid rule into a current event—without checking the applicable appendix and supervision regime.
Classifying the Format
Standard Chess
Standard chess is the ordinary competitive format governed by the Competitive Rules of Play when the time control is not classified as rapid/blitz under the appendices.
Rapid Chess
Current Appendix A defines rapid as more than 10 but less than 60 minutes per player, using fixed allotted time or base + 60 × increment for classification.
Blitz Chess
Current Appendix B defines blitz as 10 minutes or less per player under the analogous fixed-time / base + 60 × increment framework.
Base + 60 Increments Classification
For classification with increment, FIDE uses base time plus 60 times the per-move increment, not an estimate of the actual game length.
Rating-Regulation Requirements Can Differ
FIDE rating regulations can impose separate minimum time requirements from the Laws' rapid/blitz classification; is rapid and is rateable rapid are different questions.
Rapid Procedure
No Normal Move-Recording Requirement
In rapid chess, players normally do not need to record moves under Appendix A.2, while retaining claim rights that would normally use a scoresheet.
One-Minute Penalty Substitution — Current Law
Current Appendix A.3 substitutes one minute for the two-minute penalties mentioned in Articles 7 and 9; blitz Appendix B uses its own current penalty framework.
Full-Supervision Regime
Rapid uses the full Competitive Rules of Play when one arbiter supervises at most three games and each game is recorded as required by Appendix A.4.
Reduced-Supervision Regime
Without full supervision, Appendix A's reduced-supervision provisions apply, including special handling of illegal moves, flags and incorrect setup.
Illegal-Move Claim Timing
Reduced-supervision rapid/blitz can require the player to claim an illegal move before making the next move; exact current appendix wording governs.
Incorrect Setup After Ten Moves
Current rapid provisions use a ten-move threshold for specified incorrect-board/setup corrections in reduced supervision; do not teach the older three-move number.
Arbiter Calling Flag Fall
Whether the arbiter calls flag-fall depends on the supervision regime; reduced-supervision rapid makes player claim part of the procedure.
Blitz Procedure
Blitz Definition
Blitz uses the current Appendix B definition of 10 minutes or less.
Full-Supervision Regime
With sufficient supervision/recording, blitz can use the full Competitive Rules regime specified by Appendix B.
Rapid-Law Fallback
Where full supervision conditions are not met, current blitz procedure largely applies the rapid reduced-supervision rules through Appendix B's fallback.
Event Must Specify Regime
The competition should determine the applicable supervision regime consistently; players should not assume it changes mid-event because fewer boards remain.
Other Competition-Specific Procedures
Quickplay Finishes
Quickplay-finish Guidelines III apply only when announced and only to standard/rapid games without increment within their scope—not to blitz.
Adjournment — Historical/Reference
Adjournment is retained as historical/reference procedure in Guidelines I but is uncommon in modern top-level practice; treat its current existence separately from historical prevalence.
Chess960 Procedure Cross-Reference variant-specific guidance
Chess960 castling/procedure belongs to variant-specific guidance; competition administration should cross-reference the variant-specific Appendix/Rules rather than retrofit orthodox castling procedure.
Practice
Format-Difference Practice
Format-difference practice should present the same illegal move, flag fall, scoresheet and setup issue under standard, fully supervised rapid and reduced-supervision rapid/blitz.
Supervision Can Matter as Much as the Clock
Two rapid events with the same time control can use different procedural regimes because the number of arbiters and boards under supervision affects which appendix provisions apply. That is why a rule explanation should record both time-control classification and supervision.
A Practical Comparison
| Question | Standard | Rapid / Blitz |
|---|---|---|
| Must the player normally record moves? | Yes, subject to Article 8 exceptions | Usually no normal scoresheet obligation under the appendices |
| Are Article 7/9 time penalties always two minutes? | Standard rules use two minutes in the relevant provisions | Rapid Appendix A substitutes one minute in the specified cases; blitz follows its applicable appendix framework |
| Can setup irregularities become fixed after play continues? | Use the standard Laws | Reduced-supervision rapid/blitz have appendix-specific thresholds and procedures |
| Who acts on flag fall? | Standard competitive rules | Procedure can differ with supervision under the appendices |
The table is a map, not a substitute for the current appendix. For a real dispute, identify the event's exact regime first.
Event Regulations Can Add Another Layer
An event may specify default time, draw-offer restrictions, play-off controls, anti-cheating requirements or other procedures within the governing framework. “Rapid rules” therefore do not answer every question about a rapid tournament.
