How to Count Your Books: A Guide to Precision Bidding

Introduction

Bidding isn't guessing; it's a calculation. In Joker Joker Deuce Deuce (JJDD), your hand's value changes based on the "Big Four."

Guaranteed Books: The Big Joker, Little Joker, and the 2 of Diamonds. If you have these, they are locked-in wins.
Likely Books: The Ace of Spades (if the Jokers are gone) or a King/Ace in a short suit.
Possible Books: Queens, low Spades, or "cuts." If you only have two Hearts, you'll likely be able to "cut" the third round of Hearts with a Spade.
