Kg♠ Knv♠ Qn♠ A♠

Remark.—B covers the honour, because the lead was from weakness. B plays badly; he should have passed the knave. For, A has shown four more trumps, and only one other trick is required. Hence, if A has ace or king of spades, the game is won to a moral certainty; if not, no good is got by covering.
