You are West. The bidding has been as shown.
You led the ♠A, East plays the ♠9, South the ♠5.
You assume East has signaled you to continue ♠s, so you play the ♠Q.
On this trick East plays the ♠3 and South the ♠8.
How will you continue?

  You know that both East and South are now void of ♠s.
You might just switch suits, but you have a better choice.

If you play your ♠Q, East won't bother ruffing, South WILL ruff and dummy's ♠J will be established as a winner.

The best procedure is to lead a low ♠.
East will ruff and South will over-ruff but by playing this way you stop the establishment of North's ♠J. As you can see, South would have been able to discard a loser on that ♠J if you hadn't played this way.
