Up For Promotion

by Richard Pavlicek

Your 4 contract would usually be easy, but not this time. West begins with the A then a diamond to East’s queen. You have three obvious tricks to lose, and West is threatening to get a trump promotion as well.

4 × South 2

Assuming you ruff the second diamond lead, routine play will not suffice. As soon as West gets the lead with the K, he will lead a low club to East’s K. Then a third round of diamonds will promote West’s 9 into the setting trick.

Can you make West pay for his double?

Make 4 after ace and another diamond lead.

Solution

The trump promotion is in fact inevitable, but there is something you can do about the losing club.

Cross to the A in dummy and lead a diamond, which East must cover (else you could just throw your losing club while West ruffs). Now comes the spectacular play: Ruff with the ace! Beat that! Assume West discards a club to leave the position below:

Cash two more spades then ruff your last spade with the 3 as East is helpless holding only the lowly deuce. Now lead the good diamond and discard your club as West ruffs. It is a simple matter then to force out West’s K and draw the rest of this trumps.

Variation: If West had thrown a spade as you ruffed with the A, you would ruff the third round of spades in dummy, etc.

West may think twice before he doubles you again.
