Step 1 : Introduction to the question "5. "OK, one last rubber before we call it a day". This bridge player is speaking of one last... what? "
...1. "Rubber" means "dealer", so "one last deal" 2. "One last bid" 3. "One last bet" 4. "One last match" Rubber bridge is the most simple, social form of bridge. It is played by four people, two pairs, and it consists of at least two deals. A rubber - the basic unit of play corresponding to a "best of three" match - is finished when one of the pairs manages to score two full games. A game is scored when a pair declares (bids) and then successfully fulfills (makes) a contract worth at least 100 points. When a pair scores its first game, meaning it is just one game away from the rubber win, the pair is then called "vulnerable", because the penalty for failing to fulfill contracts is doubled for them. This is a way for the other pair to try and catch up.
