The objectives of a transition document are to ensure that if the last bid was from the opposing partnership, one can also double the bid of opponents, increase penalties for undertricks, but also increase the reward for contracting. The doubling does not apply to the future commandments of adversaries, unless future commandments are doubled again. A player doubled on the opposing partnership can also double, which further increases penalties and rewards.  Players cannot see their partner`s hand during the auction, but only theirs. There are many bidding conventions that assign agreed meanings to different calls to help players get an optimal contract (or hinder their opponents).

Thus, an intelligent partner can read much more than the importance of the surface in the auction.
