CONVENTION: Ace asks for an honor or count.

This convention applies to opening leads against notrump
contracts. Responder drops an honor, if he has one.
Otherwise he gives count. Using standard count signals,
third hand plays: high from two, low from three or five,
second highest from four.

After East plays the 6 of spades, West continues spades
and East wins the fourth round with the 8. The defenders
then take five heart tricks! Down four is a score of 200
to East-West.
