You hold ♠32♥AKxxx♦AQxx♣xx. You open 1♥, LHO bids 4♠ and partner doubles. What is the minimum change that you would make to the above hand where you would remove partner's double? Since this is a generic question, you may give me different answers based on vulnerability and type of game. You may also give me what variables you use to remove partner's double.
In order to answer the question, one has to know what types of hands partner might have to double 4♠. Can you double 4♠ holding ♠AQJ10xxxxxxxxx or should you have: ♠xx♥QJx♦Kxxx♣AKxx? There's a big difference between the two hands. A few experts rarely pull the double.
Kit Woolsey:---I play the double of 4♠ basically as penalties, so I would need something pretty remarkable to remove it — maybe: ♠–♥AKQxxx♦KQJxxxx.
David Bird:---I would pass partner's double on this hand and on almost any hand close to ♠32♥AKxxx♦AQxx♣xx. I would need to be 6-5 in my suits before removing it.
The experts expect the doubler to have aces and kings, not spade values: ♠xx♥QJx♦Kxxx♣AKxx for instance. So what hands do experts have where they pull the double of 4♠?
Joel Wooldridge:---If you're playing the more standard version of double here, guaranteeing some convertible values, then all I'd need changed would be either make one spade a heart, and one club a diamond, or make one spade a diamond and the other spade a club. With those hands, I'd bid 4NT or 5♦ only if I was red against white. At equal vulnerability, I'd convert to 5♦ only with the 6-5 hand and at matchpoints.
If the 4♠-bidder has eight tricks and you can make an eleven trick contract, passing the double at IMPs will be OK unless you're vulnerable and they're not. Losing three or four IMPs (+300 vs +450) is not a big swing. At matchpoints, where there is a big difference between +300 and +450, you might pull more often.
Barry Rigal:---With 5-5 shape I'd pull. With 6-4 shape and the values in the suit I'd probably pull. So make the small spade into either a heart or a diamond — but not a club — and I'd remove to 5♦ or 4NT. With 7-2-2-2 I might pass but with a singleton spade I might bid.
If you pull, it's important for partner to know your distribution. 4NT is for takeout and shows, when you correct clubs to diamonds, six hearts and four diamonds. Bidding 5♦ directly shows 5-5.
Bobby Wolff:---I would pass with the problem hand as is, but bid 5♦ if I had the fifth diamond.
Marty Bergen:---I like to play that responder's double 100% denies a spade void. As opener, I would pull with any hand containing a void. I would also pull with 5-5. At favorable, I would always pull with a stiff spade.
Jill Meyers:---I would have to have a very distributional hand without quick tricks to pull: e.g. ♠void♥KQJTxxx♦KQxxxx.
Eddie Kantar:---I avoid pulling doubles with balanced hands. I would need a singleton or void in the opponent's suit or a side five-card suit to consider pulling the double regardless of the vulnerability.
Nick Nickell:---This hand is one card away from a totally balanced minimum. It also has ♥AKAQ, which is good for defense. To pull, I would want to have a fifth diamond and a singleton spade.
Spade shortness makes a big difference. ♠x♥AKxxx♦AKJxxxx is a pull while ♠xx♥AKxxx♦AKxxx is a sit.
Henry Bethe:---Typically I would remove if my offensive potential far exceeded my defense. This could be because I have extra shape, or I have poor defensive values for an opening bid.
Steve Bloom:---Vulnerability is not a big factor. Certainly it is more tempting to defend at favorable vulnerability, but LHO can see the colors, and still bid 4♠. Partner's double essentially means that this is our hand. Finally, my decision will be based primarily on shape. Change a spade to a diamond, and I would bid 5♦. Change a spade to a heart, and the decision is very close between pass and 4NT. Give me a spade void, and I would always bid.
Kerry Sanborn:---The minimum change I would make would be to add a diamond and subtract any black card.
Peter Weichsel:---I would bid if the two of spades became the two of diamonds. At all games, all vulnerabilities. I presume that double shows convertible values.
Zeke Jabbour:---Five-level decisions are among the most difficult and understudied in bridge. Nobody would pull with the hand shown. The doubleton spade is highly unattractive. Even the addition of a diamond wouldn't induce me to pull, unless I held a singleton spade. So, in order to pull I need shape, working values, and either short or long spades. Unfavorable vulnerability would encourage me to risk the pull.
The double of 4♠ shows general strength. You're allowed to pull the double, but when in doubt take the plus score. This also means that when you double 4♠, you should be prepared for partner to pull it. This logic is good for all high-level doubles.
