How do lets and strokes work?

Question

Accepted Answer

After your follow-through you must make every effort to clear, so your opponent has a fair view of the ball, access to it, room for a reasonable swing, and freedom to hit it to any part of the front wall (World Squash Singles Rule 8). If you're the striker and that doesn't happen, stop and say "Let, please" without undue delay. A let request also covers a request for a stroke.

The referee then decides:

Situation	Decision
No interference and no reasonable fear of injury	No let
Interference, but you couldn't have made a good return	No let
You played on past the interference, then asked	No let
Minimal interference (you could still see and reach the ball)	No let
Interference your opponent was making every effort to avoid, and you could have made a good return	Yes, let (replay the point)
You could have made a good return but your opponent wasn't making every effort to clear	Stroke to you (you win the point)
Interference stopped what would have been a winning return	Stroke to you

Also:

If you didn't make every effort to get to the ball, no let.
If you had access but took a path that created the interference, no let, unless you'd been wrong-footed and could have recovered (then a let, or a stroke if it would have been a winner).
