A simple auction carries you to a small slam in diamonds. How will you play this contract when West leads a low club to the nine and ace, East returning the club three? You ruff the club return and cross to dummy with a trump. 

What now? If East holds the king of spades, a successful spade finesse will yield the contract. You can draw the last rump and ruff your three remaining major-suit losers in the dummy. 

If instead East holds the heart queen, you will fare better by finessing in hearts. You can then throw a spade from dummy on the third round of hearts, again proceeding to ruff your three remaining losers in the dummy. 

Which finesse should you take? Against 90% of the world’s defenders there is no need to guess! Lead the spade queen at Trick 3. 

If East has the king he will (wrongly) cover. If he fails to cover, rise with the ace, cross to dummy with another trump and take the heart finesse instead. You get the best of both worlds.

What will you rebid after partner’s 2C response?

Answers

In most bidding systems nowadays, including Acol, a rebid of 2H is forcing opposite a two-level response. (A rebid of 2S would not have been.) If your system requires you to rebid 3H, just because you have enough for game and do not want a 2H rebid to be passed, partner has no way of knowing whether you have five hearts or four. He will have to guess what to do when he has only three hearts.

Marks: 2H-10, 3H-7, 3NT or 2NT-4.
