Those Spots make a difference

Here is a safety play for five out of six tricks. Plenty of entries. The play depends on the spot cards.

Problem 1. J6 opposite AQ7432

Problem 2. J6 opposite AQ7532

In problem one and two, all 3-2 breaks give no problem. THe extra chance comes for 4-1 break. In problem 1, the spot cards are so small, that the only extra chance comes from a singleton king. Start with the A. In problem 2, the presence of the 5 allows you to handle KT84 or KT94 onside, and you can run the Jack on the first round if covered all round, on the next round advance the 6 and run it. If he covers with the 8, your 75 are now equals for a builder against T4.

Afterthought, of all the 4 -1 breaks singleton king is 1/5th, 5.6 % For 8 or 9 to be singleton and only to west, you have 2/5 * 1/2 * 4-1 breaks or the same 5.6%. Can Jannersten be overlooking this since you have to commit to a line of play on problem 2? "Play Safe and Win" Jannersten and Wohlin.

Welcome to Ramesh's BRIDGE BLOG

In these pages, I comment on hands from Bridge Base Online ACBL tourneys. I play in these with a variety of partners with different degrees of skill. I might present a hand or two from my collection of bridge books, every now and then. I am more interested in play and defense than in complex bidding systems, but I do follow the cut and thrust of Vanderbilt and World Championship Vugraph and try to keep abreast of expert practice in the obstructive and constructive bidding system department. I may also feature, newspaper-style, famous hands from important matches that I saw on Vugraph.

NOTE: For JUNE, I am experimenting with adding BBO's Handviewers, which make bridge movies embedded. Just
scroll down beyond the few sampled book covers and you arrive at the blogs that play themselves with the NEXT button. THANKS, BBO!!
