There are certain auctions where we have made a bid that has “fully described our hand” and we leave the bidding up to partner. In auctions like these we usually are not very sure of what partner has for their bid and we want to leave any further decisions up to them. But sometimes we have more shape than partner expects or our instincts tell us that it is right to bid on. When that is the case we do NOT want to just take over and bid again – we told partner we would not bid any more after our first bid. In an auction like this we can use a double as a conventional bid saying “I want to bid more”. This is called an I Want to bid Double and it applies in very specific situations.
(556) Competitive Auctions: Anti-Lead Directing Doubles
Lead-directing doubles can be helpful in getting partner off to a good opening lead. These lead-directing doubles are common when the opponents make an artificial bid. When the opponents make a cuebid of our suit, a lead-directing double is also very common. Here we focus on this situation in detail to structure our agreements to allow us to communicate in the most effective way we can.

In order to do this week need good agreements with partner, especially about the meaning of cuebidding the opponent's suit. Let's make sure we have good agreements in these situations.
