Irish poet and dramatist William Butler Yeats said, "Think like a wise man but communicate in the language of the people."
    That is good advice for anyone, but especially for a person writing instructive material.
    In yesterday's deal East had to signal correctly at trick one, communicating to his partner how he wanted the defense to proceed. Today, we turn to the declarer, who must also understand communication plays. I hope I can accurately communicate the idea.
    You are South, the declarer in four spades. West leads the club king. What would be your line of play? Did West have a better opening lead? What do you think of the bidding?
    Going in reverse order, North, with seven playing tricks (one heart and six diamonds) was cautious in rebidding only two diamonds. He might have continued with two hearts, a strength-showing reverse, but with a void in his partner's suit, that would have been an overbid. Rebidding three diamonds would have been a reasonable compromise.
    The contract can be defeated with an initial diamond lead. The defenders can collect one spade, one heart, one club and one diamond ruff.
    If you win trick one and drive out the spade ace, East will return his diamond, stranding you in the dummy. You can exit with a club, but West will win and give his partner a diamond ruff. A heart shift then kills the dummy and sets up a heart as the setting trick.
    Instead, duck the first trick to open the communication lines to your hand via a later club ruff. West has no riposte.
