It was here that I ran across what I referred to as the "JCC double." It was a takeout double with shortness in an unbid suit. A typical auction would proceed as follows:
(1♥) - x* - (P) - 1♠
(P) - 1NT** - (P) - 2♠***
(P) - 2NT****
* - the JCC double - could be a real takeout double, but....
** - Pard, I don't like your suit.
*** - But I really have spades!
**** - Pard, I really don't like your suit!
Eventually, the message got across, and they played in another suit or notrump.
In all of my experience at this club, the doubler never had extra values for the double followed by NT bid.
Same at my club - when they have an opening hand, they feel they MUST bid, and if they have nothing to overcall they double. So usually they either have lots of cards in our opened suit, or a takeout double. It's so annoying when their pard bids a suit, and they happen to have support for it - they have one or two cards in the other unbid suits (and four or five in ours) but four cards in the one their pard bid. However, it's great in the sense that when their pard has a six-card suit, they don't feel comfortable bidding it at a high level (in case there is only singleton support), so we usually get away with murder.
