Welcome to the world of advanced bidding conventions. In this deck, you'll learn powerful tools to describe your hand with more precision, especially in competitive situations. These bids help you find the best contract and sometimes disrupt the opponents' auction.

Let's start with a way to show a very strong hand when your partner opens one of a major suit. The Jacoby Two No Trump convention is a direct, game-forcing raise that promises excellent support and high-card strength.

Now, let's look at a bid that describes your hand's shape in a dramatic way. A Splinter bid is an unnecessary jump in a new suit that shows a singleton or a void in that suit, along with a great fit for your partner's suit.

For example, if your partner opens one spade, and you have game-forcing points, four or more spades, and only one club, you would bid four clubs. This tells your partner you are very short in clubs, which helps them evaluate their own hand for a potential slam.
