Match 2 - Board 18

Board 18
Our side vulnerable

♠ A K 10 9 5 4 2 K ♣ A Q J 9 4

I open one club in second seat. LHO bids one diamond, and partner bids one notrump. In the post mortem, Jack will tell me I should bid two spades at this point. I disagree. I think two spades should suggest doubt about notrump. With three hearts and the diamond king, notrump looks like the right strain to me. The only question is how high to raise. Point count undervalues this hand because of the concentrated values. Against that, honors in the opponents' suit are worth less when partner shows values there as well. I decide the hand is worth only two notrump. Partner goes on to three, and West leads the nine of diamonds.

East takes my diamond king with the ace, and I play the deuce. How easy will it be for East to find a heart switch? It depends upon his heart holding. It would probably be easier for him to switch from the king than from the ace. If he has the ace, he may think he needs that card as an entry.  From his point of view, I could have

♠ x x x K Q x J x x x ♣ K x x,

in which case three rounds of diamonds would be the right defense.

East cashes the diamond queen--four--three. The fact that he's cashing the diamond queen is encouraging. If he intended to switch to hearts, he probably would have done so without setting up my diamond jack first. Is there any pitch I can make from dummy to encourage him along this path? A spade pitch suggests I don't have the spade queen.  It also suggests I intend to play hearts myself. Why would I need to keep all three of dummy's hearts otherwise? Accordingly, I pitch the nine of spades.

East, to my dismay, cashes the heart ace--six--eight--four, then plays the nine of hearts. The ten is the percentage play by restricted choice. It is also the play indicated by East's defense. East would surely not cash the diamond queen if he were planning on underleading a heart honor. He cashed it because he was planning on cashing whatever red tricks he could off the top. I play the ten. West wins with the jack and cashes three more heart tricks. Down three.

Everyone played three notrump. Two pairs made four; everyone else was down three like me, so we get four matchpoints. Unfortunately, this drops us to second place. We seemed unbeatable only a couple of boards ago.

Did my spade pitch somehow make East suspicious?  Would a routine heart pitch have been more effective? Just to make sure, I replay the board, trying each of the twelve possible discards from the dummy at trick two. East shifts to ace and a heart whatever I do.

  1. Why don't you have any doubts about notrump?
    I would have, because of my hearts.
    Partner did not negative double and opening leader is marked from the bidding with length in hearts behind partner.
    3NT is quite unlikely to make if partner can not stop hearts (even if hearts broke 4-3).
    Granted it would be nice to be short in hearts for bidding 2S and with 3 little hearts no alternative game contract looks promising - if partner had a heart less 4S would come home - but stopping in a part-score of a black suit instead of 3 down vulnerable will be worth a lot of match-points and almost as many IMPs as a game swing at IMPS.

    Playing with Wbridge5, Wbridge5 bid 3NT over 2S, which still looks more sensible to me than going straight to 3NT.

  2. So, how did some pairs make it? I guess they must have had a different auction which causes a different defense.
