YMCA hosts open pairs qualifying

August 10, 2018

The YWCA afternoon weekly duplicate will hold its annual North American Open Pairs qualifying game this Monday. Players who finish average or higher or earn master points at the game will automatically qualify for the next stage of the event, to be held this fall at the New England District playoffs. Master point awards for the game are half red, half black.

Duplicate players are reminded that the Connecticut Summer Sectional tournament will begin this coming Friday, Aug. 17, at the Annunciation Greek Orthodox Church on Newfield Avenue in Stamford. The three-day competition drew a record turnout when it was held in Stamford for the first time last year. Details of the tournament, which appeared in this space last week, are available at www.ctbridge.org.

Today’s quiz: We continue this week with the current series of quizzes on basic bridge probabilities. In the following problem, you are given your own and the dummy’s holding in a particular suit and are asked to determine the best percentage play under the specified circumstances.

YOU: H 5; DUMMY: H AQJ10.

You are playing in a club contract and must produce three tricks from this suit without losing a trick to the king. You have ample entries and trumps in both hands. How do you proceed?

Answer: There are two ways to attack this suit: take a finesse against your left-hand opponent, cash the ace and then trump a heart, hoping the king will fall, or cash the ace and lead through your right-hand opponent, trumping the king if he plays it and discarding if he does not.

This might therefore look like a straight guess as to who has the king, but since you need three tricks from the suit without losing to the king, there is only one correct play. Crossing to the ace and taking a “ruffing finesse” through RHO will yield three tricks without loss whenever RHO has any number of hearts including the king, an even 50-50 chance. As opposed to this, leading to the queen, cashing the ace and then ruffing a heart in the hope that the king will fall wins only when LHO started with Kx or Kxx, failing whenever he has four or more cards in the suit. Since this play will succeed much less than half the time (about 16 percent), the ruffing finesse is far better.
