The double of 6N called for an opening lead of a club...dummy's first bid suit...at least, this is the traditional meaning of a Lightner double of a voluntarily bid slam with us silent. However, we can deduce that this is not the case here...or, rather, that we don't need to lead clubs if it were.
It is a good thing that LHO didn't work this out....he is looking at solid clubs, I assume...so should have known that the double was a gift from the heavens....
Typical layout: Jxxx x Qx AKQJxx opposite Qx AKQx AKJ10x xx
So here, a spade seems clear.
Two wrongs can make a right, it seems. The double of 6N eliminates the chance of beating the contract, while the runout to 7♣ clues us in to the correct lead.....which is the suit that one would expect to lead were the contract 6N undoubled.....no way one is leading one of declarer's suits on this auction, and declarer will usually, on this type of auction, need to attack clubs anyway, leaving only the spade suit.
BTW, a layout consistent with the double of 6N being 'correct' would be something like AKxx x Qx KJ10xxx opposite Qx AKQx AKJ10x xx.
The double of 6N said he was on lead against that with an AK
I led a spade, in fact it didn't matter.
Dummy was AKQ, AK93, QJT86, K
Declarer had J542, Q72, VOID, AQJ863
Partner has 876, JT4, AK4, T742
What I said to partner was that even if 7
♣ was losing a diamond, there was every chance that I'd find the wrong lead and the diamond would go west on dummy's hearts. I had a much smaller objection to the double if partner would have been on lead against the likely running place.
Anyway the double turned +100 into -2330.
