Your hold: ♠ J854 ♥ 53 ♦ Q5 ♣ AQ872

Lead the spade four. How is declarer going to play the hand? He will draw trumps and cash the hearts for black-suit discards. You will need at least one trick from the spade suit, maybe more, so you had better lead a spade in case a club trick is not standing up. Considering your partner’s five-club bid and your right-hand opponent’s five-diamond call, that may just be the reality.
