C: Blitz

C1. A 'blitz game' is one where all the moves must be made in a fixed time less than 15 minutes.

C2. Play shall be governed by the Rapidplay Laws as in Appendix B except where they are overridden by the following Laws.

C3. An illegal move is completed once the opponent's clock has been started. The opponent is then entitled to claim a win before making his own move. Once the opponent has made his own move, an illegal move cannot be corrected.

C4. In order to win, a player must have 'mating potential'. This is defined as adequate forces eventually to produce a position legally, possibly by 'helpmate', where an opponent having the move cannot avoid being checkmated in one move. Thus two knights and a king against a lone king is insufficient, but a rook and king against a knight and king is sufficient.

C5. Article 10.2 does not apply.
