Accurate defensive play is worth many matchpoints in every session we play. Board 12 was one such hand. It was played 16 times on Monday evening. Ten declarers made 11 tricks for an above average score whilst four were held to 10 tricks for a great score for the defenders.
The bidding is straightforward. North opens 1D and South, who is to strong to respond 3NT for fear of missing a slam, responds 2C awaiting developments. North with a super suit holds too few high cards to bid anything except 2D. After this weak rebid South bids 3NT to end the auction. The resultant contract is at risk on a spade lead if the diamond finesse were to lose but is the highest scoring contract and where you would want to be at pairs. At teams where making game contracts is paramount you might prefer to reach 5D.
West is on lead with an obvious spade lead but has to decide the choice of card and think about the bidding. South would probably have bid a 4 card major if he held one so we can assume that we has not got one. Personally I do not like to underlead touching honours such as KQ, QJ or J10 although many books would advise to lead low from these holdings, especially if they are not supported by another high card. So all experts would lead the highest honour from KQJ, QJ10 and J109 and most would do so from KQ10, QJ9 and J108. With lesser holdings they would chose the 4th highest. On this board the majority would try the SK which is just as well on this hand as the 4th highest lead would be won by dummy with the S9.
On the lead of the SK dummy plays its singleton and East has to decide which card to play from the 8762. If you play normal encourage/discourage we play the S2 to deny the ace or the jack. If you play reverse then you play the S8. If you play mainly distributional signals it gets slightly more difficult when holding 4 small cards .My view is to play 3rd highest (S6) to discourage with four cards and 2nd highest to encourage - so the S8 from J876. This sort of agreement is more complicated than simple encourage/discourage but will help in a slightly different situation where declarer holds AJ doubleton and East can be read for 5 small cards when he plays the S2.
On this hand after East discourages on the SK lead the declarer (South) must decide what to do from his SAJ3. This is an easy decision as winning with the ace and taking a losing diamond finesse will result in defeat of the contract when a spade is returned through your remaining J3. Therefore we have to duck by playing the S3 leaving the AJ to guard the suit. Should West lead another spade it will be won by the jack which would make the contract easy to make The contract is still in danger if West can lead a heart to his partners ace and get a spade return when the diamond finesse will need to work.
When the SK is allowed to win the first trick it is West's turn to think. The card played by his partner should make it clear that he does not hold the ace or jack of spades so that a continuation will be a losing play. If we consider the other suits starting with clubs. Declarer has bid the suit, we have 4 cards and dummy has 3. Therefore our partner is short in clubs and will not be able to get the lead unless he has the ace. If he has the ace and returns a spade declarer will win at least 7 diamonds, 3 clubs and 1 spade and I will lose my HA. Alternatively partner holds the DK as well when the contract will always go down. Therefore a club switch must be wrong.
Now lets look at a diamond switch. If declarer has the DK he will start to play clubs through partner and cannot make a losing guess. He will make 1 spade, 7 diamonds and several clubs and there is some danger that we will never make our HA. If partner has the DK, when he wins it. he will return a spade to clear our suit. Declarer will win 1 spade, 6 diamonds and several clubs. Again we might not win our HA. Either way a diamond switch must be wrong.
So we have worked out that we need to play a heart but which one? if we lead a small one through the KJ in dummy partner might win with the HQ to return a spade which would be good. Could anything go wrong? Imagine partner with HQ9xx. If declarer plays low partner might play the H9 and lose to the 10.The H9 is the correct play if you have led from the H10. Of course you will argue that you would have led the H10 in that situation but partner had a tough decision to make. When declarer lacks the HQ he may guess to play dummy's king and could run both the minors so we fail to win our HA.
When you think back to the bidding South is favourite to hold the HQ as he did jump to 3NT and might not have done so without a heart stopper. After a full analysis it becomes clear that we should cash our HA and play another. If partner has the HQ and an entry in one of the minors he will be able to cash the queen and the long card in the suit.
On the actual hand declarer would win the second heart in hand to take the diamond finesse. Partner will win the DK for our third defensive trick and we get a near top for holding declarer to 10 tricks .Of course we managed it?
I am afraid not. it was the last board of the night and we were sleeping. Georgia lead the SK and continued the suit into the AJ. Declarer took the diamond finesse which I ducked. Georgia showed out on the second round of diamonds and I won the king. Without any thought I returned a spade giving declarer 11 tricks on top.
I should have stopped and counted. I knew declarer had 2 spades and 6 diamonds and some other high cards. If Georgia has the CA then she will not have the HA so declarer might win 3 tricks in hearts to make 11 in total. If Georgia has the HA she is in danger of being squeezed in hearts and clubs so I should have led to her ace - but which one?
From Georgia's perspective she could count declarer for plenty of tricks unless I had the CA so she should have signalled for a heart switch to make sure that she got her ace .Thinking and counting can get tough late in the evening!
