And you, South, hold:
| A Q J 8 2|
A K J 5 4
Many experts recommend a bid of 4 , not for the purpose of trying for slam (which is relatively obscure), but to enlighten partner as to the nature of Souths hand. The contention is that partner will be in a better position to judge whether to double or bid 5 in the event that East-West persist to 5 .
I disagree. While the argument of disclosure may have merit, there are arguments in favor of concealment that are more important in my view. The debate is complex and will probably not be solved in this or any other article. Nonetheless, I am a concealer and wish to make some points on that behalf.
In the above bidding sequence I recommend a direct bid of 4 . Should South become declarer (certainly likely), this will be to his advantage in the play. The defenders will have no clue as to Souths side-suit lengths and the chances of a defensive error are thus increased. Disclosing the diamond suit would tip off the defense.
Another point is that concealing the diamond suit will make it more difficult for the opponents to decide whether or not to sacrifice. The enemy will have less information on which to determine the degree of fit of their hands. Keeping partner in the dark also keeps both opponents in the dark.
A third advantage is that a 4 bid (or any other new suit bid beyond three of the agreed major) can be recognized as a legitimate slam try. Knowing that your basic strategy is concealment makes partner aware you are trying for more than just game.
Of course, the above just touches on the subject. With the myriad of possible auctions, and varying vulnerabilities, the better strategy (disclosure vs. concealment) might vary from situation to situation. In general, though, I believe that concealment is the proper course. I could introduce example deals to illustrate my point, but any such deals would be biased because of the fact I chose them. Indeed, one could make almost any point convincing by choosing the right hands.
2. Aids partner in the defense (sometimes, the opening lead) should your side end up defending.
3. On rare occasions might lead to a slam based on the discovery of a tremendous double fit.
2. Avoids aiding the opponents in their decision whether or not to sacrifice.
3. Should you and partner be defenders, avoids aiding the opposing declarer in his play of the hand.
4. Allows the use of a bid in a side suit as a legitimate slam try.
