Double, to me, is insane.
Yes, it is values with no clear bid, but it will reach 3N only when partner has a stopper, so that either 3♠ or 3N would work just as well. It will reach spades only when partner holds 4 of them, and then 3♠ works as well or better, and it will never find a 5-3 spade fit... unless we are planning on torturing partner with 4♠ over 4 minor by him. And, if he does pass, are we really going to be happy?
From the insane:
Your conclusion is not valid. We have many time played a 5=3 spade fit (or heart fit on similar auctions) where partner bid a three-card major in response to our double. Partner knowing you might double on this hand can bid a three-card major on a tough hand or one that is willing to play spades in Moysian.
Also having doubled and when partner repeats their minor we can bid 4
♠ to show five spades. Since we did not bid 3
♠ or 4
♠ the previous round we are most likely to have five spades or six poor spades in a flexible hand for this auction and therefore partner will know to pull with a singleton.
In general after the opponents have bid and raised hence they have found their fit but we have not we are already behind. It makes a lot of sense to me to be able to make constructive but not forcing bids when we have an undisclosed long suit and no or only a partial fit for partner. This auction is not the ideal advertisement for this since the auction is so crammed at 3
♥ nevertheless it still seems to work on a wide range of hands.
