Useful x-ray

A useful x-ray is an x-ray worth acting on: the piece beyond is under-defended, a discovery is possible, or the line forces a concession. Many optical x-rays are noise.

Why you should notice it

Players either ignore all x-rays or freeze on harmless ones. The useful skill is priority: after you can see the line, ask whether it actually hurts.

When to check it

Same stages as x-ray. During threat assessment, which of *their* lines should change your move? While finding a move, which of *yours* should you try to use? The second question — “does this actually matter?” — is the habit.

Why players miss it during games

A busy middlegame is full of batteries that do nothing. If every line feels urgent, you stop looking. If none feel urgent, you miss the one that wins a piece. That filter is closer to how a strong player spends the first seconds.

How WayChess trains it

You mark useful x-rays for you and for the opponent, with feedback when you include a line that does not threaten anything real. Build it on top of the basic x-ray habit.
