I was just thinking about the stumping rule the other day and I came across a scenario which I couldn't definitively say was out or not by reading the rules.
Scenario
Given that you cannot be stumped off a no ball, but you can be ran out and the difference between the two is determined by whether the striker is attempting a run or not. What happens if the non striker attempts a run but the striker does not (on a no ball where the striker is out of his crease and the wicketkeeper takes off the bails at the strikers end)?
