While I didn't play last Tuesday an acquaintance pointed out this neat hand from the Woodberry duplicate.
Both sides have a double fit in a major and a minor and a major is usually the place to be at pairs but on best defense you do better in the minor on this hand. Par result is -130 for N/S which I see occurred at one table
If N/S are defending hearts I cannot see anyone finding the DD defense to hold it to 8 tricks (diamond lead, ruff the return, underlead all the club honours to the jack for another ruff with a spade to come). However declarer will likely lose two diamonds and a ruff anyway in the natural order of play.
If E/W are defending spades it should be possible to match the DD result although I see no one did. After a top heart lead East plays the queen showing the jack. Now West can switch to his club. East hops with the ace on the first round of trumps, gives a club ruff and West underleads his hearts to get a second ruff. Is there any alternative defense with those clubs threatening on the table?
The bidding is interesting too. Most North's didn't open which I can understand but now is it practically impossible to get the spades into the auction and being outranked in clubs you will usually defend a heart contract.
If North does open then the spade fit is found after 1C-P-1S-2H-2S. East will bid 3H now and the question is can North/South justify bidding again at this vulnerability? If you play support doubles and a weak NT (not recommended!) then perhaps South can risk it knowing of a likely double fit. Otherwise maybe North can place their partner with only two hearts and not more than 4 diamonds (although playing Walsh style some South's may have longer diamonds than spades) and again bid a third spade based on the double fit.
Might East make a matchpoint double of this thinking 3H is making? As you can see from the traveller this gives you good odds. If it makes you were getting a very poor board anyway and a double and successful defense takes you from an average to an outright top
One final thought. A precision club auction might start 2C-P-3C and now E/W might well get too high. And a canape auction could start 1S-P-2S and have the same effect.
