# Can I use the perpetual check or chase rules as a tactical weapon rather than just knowing them defensively?

These answers restate the rules implemented by our open-source engine, which follows the WXF laws and is regression-tested against the official 110-diagram repetition casebook. Where an answer refers to a specific position, that position lives on the linked reference page, where the build verifies it against the engine before publishing.

> **Yes.** Because perpetual check and perpetual chase are adjudicated against whichever side is doing the checking or chasing without variation, you can sometimes deliberately steer a position so that continuing your opponent's own attacking pattern would put *them* in violation of the rule, forcing them to stop or lose regardless of the material on the board.

## How this actually comes up in a game

If an opponent is checking or chasing one of your pieces repeatedly without making real progress, recognising that the rule requires them to vary, not you, changes how you should respond: rather than panicking about the repetition, check whether they are the one who will be forced to stop. See [perpetual check and chase](https://xiangqimaster.com/rules/perpetual-check-and-chase) for exactly which patterns count.

## Why this is a genuinely different skill from just knowing the rule

Knowing the rule defensively means not panicking when checked repeatedly. Using it tactically means actively steering a position, sometimes offering a piece that looks vulnerable, specifically because chasing it repeatedly would trap the opponent under the same rule that would otherwise threaten you. It is a rules-aware tactic, not just rules knowledge.

## Related questions

Does this work the same for perpetual check and perpetual chase?

The underlying logic is the same for both, though the specific conditions that count as a chase differ from what counts as a check; check the specific casebook for edge cases.

Is this an advanced idea?

Reasonably so; it depends on already being comfortable with the repetition rules themselves before trying to use them offensively.
