Here are the following system cards and diagrams :

  • The well-known system cards for 4-card Major and 5-card Major, which are used at bridge club competitions.

  • Detailed system cards for both 4-card Major and 5-card Major bidding systems.
    These system cards give ample attention to their responding bids after the opening bid (such as response, overcall, rebid and so on).
The colors used in the heads of the opening bids correspond to the colors of their responding bids. In this way an opening bid and the responding bid are easy to find together, for example :
- the color in the head of an opening in 1 is light yellow and therefore the color in the head
  of the responding bid is also light yellow..
- the color in the head of an opening in 1NT is light blue and therefore the color in the head of the
  responding bid is also light blue.
- etc.

  • For the bids after opening in 1NT en 2NT there are diagrams of the bids according Jacoby and Stayman.
