Du­pli­cate play­ers brush up for fall tour­neys

Greenwich Time - - NEWS - STEVE BECKER Bridge in Green­wich

Af­ter a rel­a­tively quiet month on the area tour­na­ment scene, lo­cal du­pli­cate play­ers will have their chance to get back to the ta­bles with three sep­a­rate com­pe­ti­tions sched­uled for Oc­to­ber.

First up will be the an­nual seven-day Dis­trict 3 Au­tumn Leaf Re­gional from Oct. 8 to Oct. 14 at the Crowne Plaza in Dan­bury. Fur­ther de­tails on this tour­na­ment will ap­pear in this space at a later date, but for im­me­di­ate in­for­ma­tion, con­tact www.bridge-dis­trict3.org.

Two weeks later, the an­nual three-day Con­necti­cut Fall sec­tional tour­na­ment will be held from Oct. 26 to Oct. 28 at the Keeney Memo­rial Cul­tural Cen­tral in Wethers­field. Fur­ther in­for­ma­tion may be ob­tained at www.ct­bridge.org.

Fi­nally, there will be a STAC week at lo­cal clubs in mid-Oc­to­ber, with the op­por­tu­nity for all con­tes­tants to earn sil­ver points dur­ing that week.

To­day’s quiz: Here is an­other in the cur­rent se­ries of quizzes on ba­sic bridge prob­a­bil­i­ties. In the fol­low­ing prob­lem, you are given your own and the dummy’s hold­ing in two dif­fer­ent suits and are to de­ter­mine the best per­cent­age play in the spec­i­fied cir­cum­stances.

YOU: S AQ5, D AK76; DUMMY: S 432, D 5432.

You are play­ing a notrump con­tract and are in dummy for the last time. You need an ad­di­tional trick and can­not af­ford to lose the lead to the op­po­nents more than once. Should you play to set up your fourth di­a­mond, or take a spade fi­nesse?

An­swer: A few weeks ago, the very same prob­lem was pre­sented, but there was one less di­a­mond in dummy. In that cir­cum­stance, it was stated that the best per­cent­age play was to take a spade fi­nesse, since that of­fered a 50 per­cent chance of suc­cess as op­posed to the 36 per­cent chance of a 3-3 di­vi­sion of the miss­ing di­a­monds.

Here, though, the ad­di­tion of the fourth di­a­mond in dummy al­ters the per­cent­ages sig­nif­i­cantly. All you need now to pro­duce the de­sired ex­tra trick is a 3-2 di­a­mond di­vi­sion, which is bet­ter than a two-out-of-three pos­si­bil­ity (68 per­cent). Con­se­quently, since you can­not af­ford to lose the lead twice, you should not risk the 50 per­cent fi­nesse, but should go about set­ting up the long di­a­mond im­me­di­ately.
