When partner opens the bidding and the opponent makes a takeout double, we need to know how to deal with this interference. We first want to consider what is likely to happen in the remainder of the auction. If we have just a few values (minimum hand, less than 10 HCP) then this will likely continue to be a competitive auction – with us having about half the values in the deck and the opponents having about half. In a competitive auction, it becomes important that we are able to show our suits (and find our fits) quickly so that we can effectively compete in the bidding. Thus, we want to construct a system that will allow us to do this!
