The '''Threat Move''' is a quite general term in chess or computer chess, since any forced [[Tactical Moves|tactical]] or attacking move might be considered a threat move. Anyway, it seems the term is usually related to [[Null Move Pruning|null move pruning]], and refers to a move which refutes a [[Null Move|null move]] by a considerable [[Fail-Soft|fail-soft]] margin. It might be used along the [[Killer Heuristic]] to refute [[Sibling Node|siblings]] of the child node below the null move. Beside [[Move Ordering|move ordering]] issues, [[Null Move Pruning#ThreatDetection|threat move detection]] might enable or trigger [[Extensions|extensions]], for instance [[Mate Threat Extensions|mate threat extensions]] or the [[Botvinnik-Markoff Extension|Botvinnik-Markoff extension]].<br />
