You’re today’s declarer at four hearts. You have more trumps than you need. You have two side suits you would rather see the opponents lead. (You would like West to lead diamonds, East to lead clubs.) And you can make it costly for either opponent to lead spades.
Those conditions suggest you look for an end play: giving an opponent the lead when anything he does will help you. Can you spot the best line of play?
If West has the queen of spades for his opening lead, your game is cold. Take dummy’s ace of spades and draw trumps. Next cash the A-K of clubs, lead the jack of spades and discard your last club: a loser on a loser.
West takes the queen but is stuck. If he leads another spade, you ruff in dummy and discard a diamond, losing at most two diamonds. If West leads a club, you play dummy’s jack, and if East can cover, dummy’s fourth club will be a winner. If West leads a diamond, your king will score for your 10th trick. This week: end plays.
Question: You hold: ♠ K Q10864 ♥ 3 ♦ AQ8 ♣ 765. Your partner opens one heart, you bid one spade and he jumps to three hearts. The opponents pass. What do you say? Answer: Your partner’s jump in his own suit is invitational to game, not forcing. He shows a hand worth about 17 points with six (or perhaps seven) good hearts. Bid three spades. If you had a weak hand with long spades, you would pass, hence any further bid you make is forcing.
