Weak jump-shifts are alertable!

The STOP CARD is used to alert the opponent to take caution before making their next bid as it will force them to a higher level.  The opponent should pause (and think) for at least 10 seconds before making their next bid.

BOTH pair members MUST have identical convention cards filled out and available for the opponents perusal.  Failure to do so results in neither member of the pair being able to use ANY convention until the cards are properly filled out and available.

Convention cards are for the opponents not for either pair member to view during the auction or play of the hand!
