Hi,
a Diamond.
Ok, it maybe that the double of 5D was based on shortage,
a void, an the double of 6NT cancels this message, requesting
another lead.
Personnaly I think the 2nd double is based on AK in a suit,
assuming my partner is sane (?!), and the XX is just garbage,
but it may well be the other way round.
If I hit shortage, I wont kill any tricks our side has, which may
be good as well.
With kind regards
Marlowe
Exactly as u guessed, West had
♦AKTxx. And u also gave the reason for me asking this. After this board I dunno whether the 2nd double would create confusion for partner, and wondered what's in standard methods the 2nd X would mean to most people.
In the end, partner did lead
♦2, and
♦QJx was not together in declarer's hand

As to why the bidding went like that, I can never know...
NB: Only a
♦ lead (any
♦ of course) can set the contract. If E lead anything else, u give them 6N, as actually happened in one table where the auction went p-1
♣-p-6NT-p-p-p, and the only other honour between the two hands was an onside
♣Q
W N E S
