On which trick will the moment of truth arrive?

Some hands warrant a disciplined play. The picture resembles so much with a text book variety that you merely go through the motions irrespective of the actual contract. Here is a hand I played last week in a face to face event(, after quite some time).
If computer playing programs ever had feelings, those would probably be something like my feelings after having played that hand.

The moment of truth arrived quite a few tricks (which trick would that be?) down the road. The distribution rewarded the discipline, so did the Match-Points.

How quickly will you play next card?

Almost half of our mistakes are due to hasty play. Good players who are perfectly capable of finding the winning play if only they gave some time to think about it end up losing a board by playing too hastily.

Here is a problem from the semi-finals of Poddar National Masters that is being played in Kolkata this weekend (6-7 August 2011).

Have a look at the diagram below. West led the SK, thought for some time and shifted to the DQ. Declarer won DK in Dummy and successfully ran the H9 at trick three... He made the fatal mistake next. Can you see what might have gone wrong?

Correction of Error : Bridge Column (Times Of India) 11 April 2010

In my Bridge Column article on Sunday 11th April 2010, a serious error has crept in. I am sorry for the same.

I have quoted excerpts from Paul Marston's guest editorial in the March 2010 issue of the International Bridge Press Bulletin not from WBF President's message, however, the article begins with a quote from WBF President's message.

The article should read as follows:

The first round of the Bermuda Bowl 2009 did not go well for India. Here is a deal from that round. There was a mildly interesting lead problem. Holding KTxx,Qxx,xx,xxxx; what do you lead if righty opens 1H and the bidding goes 1H P 2C P 2D P 2H P 2S P 4H PPP? Make your choice before reading on..

Is the fancy play needed?

Posted by: admin on Sunday, July 05, 2009 - 06:03 AM

This was the hand I discussed in today's column. South plays in 4S after West opens the bidding in the third seat with a 1D bid but passes on two further rounds. West leads a top Diamond and shifts to the CQ. South wins and plays a small Heart and West makes the fatal mistake of ducking.

You are watching the play on the BBO vu graph and you notice that the contract is makeable at this point. Someone else (Gochi Oddkar, the proverbial oddity-seeker) notices that South can make the contract even if South cashed SA at trick four.

My partner Dr Harish Sahni as east dealer opened 1 D.We play prepared diamond. South bid 2 spades weak jump overcall.I Dr. K L Bandi thought and bid 3 clubs thinking that if it is doubled I can switch to hearts. south passed and Dr Sahni thought and decided to bid 3 notrump and then all pass. south led Hx. Dr Sahni made both K Q and played x spade south rightly played K thinking that if east had S A Q X the entry to west will be blocked..Now south was in dilemma.Thinking that if east had doubleton club ACE LOW C LEAD WILL GIVE ENTRY TO DUMMY so he rightly played D queen-x x to east King. Now east played low spade and dummys jack won and ran 3 hearts.south discarded low club on spade jack and and club Jack on last heart.North discarded 2 spades and one club.now east played C8 from dummy andsouth jumped with ace and played D ace and continued with diamond.east discarded low diamonds and last 3 cards were Diamond J and spade A Q.Thus we ended in making 10 tricks. EW being vulnerable ended +630 andscoreed +12. datum being. -20 We were the ony pair in whole field to make 3 NT.
Iff you have any querry please write to me . The deal was played on 11 jan 09 at yeshwant club

A safe plan (With solution)

Posted by: admin on Wednesday, January 07, 2009 - 03:33 PM

On the diagrammed deal, not many North players would prefer to spread their cards on the table when 6Nt is an attractive option. Perhaps, it isn't a a good idea to play in six Clubs and risk a Heart ruff on trick two. Can you, playing as South justify the confidence partner has placed in your Dummy play skills?
