Mating threats and alternating checks

A mating threat is a move preparing a check or series of checks leading to mate (19.2). It is distinct from an immediate check. Article 20.2 allows perpetual mating threats and alternating check/mating-threat sequences to be drawn if neither side varies, subject to the actual nature of the moves.

Quick answer

First ask what is threatened

  1. Is the King currently attacked? Classify a check.
  2. If not, is there a threat of a checking sequence that mates? Examine a mating threat.
  3. Does the same move also chase material? Read the relevant Chapter 5 case before ruling.
  4. Compare both sides' full repeating sequences.

Counter-mating threats

Chapter 5 §5 explains the case where each player resolves a mating threat while creating one. If neither changes the permitted sequence, the ruling is a draw. The printed Diagram 10 line has an apparent mismatch with its prose; this page explains the section without inventing a corrected diagram.

FAQ

Does every dangerous attack count as a mating threat?

No. Article 19.2 concerns a threat leading to checkmate through check or a series of checks. A vague positional advantage is not enough.
