Blueberry Cottontail Club
This bidding system is a hybrid between a modernized Blue Club and Larsson’s Cottontail Club. To make 3-card major raises safer, major suit openings promise 5+ cards or unbalanced 4 cards.
Despite of the strong club opening, this system has a strong notrump as suggested by Cottontail Club and Good, Better, Best by Jan Eric Larsson.

Canapé
In contract bridge, canapé stand for bidding a shorter suit first. This treatment is common in strong club systems.
- We systematically bid a 4-card major despite of a longer minor in many cases.
- Canapé does not occur between major suits. This helps choosing between major suit games.
- Opener bids 1♦ with 14–15 points, 5=M, and 4+♦.
Lauria-like Gazzilli
Another recurring pattern in this bidding system is a generalization of Lorenzo Lauria’s Gazzilli.
- Our last two bids are 1M-1NT or 1♥-1♠ (Kaplan interchange), a natural major suit followed by a suitless response.
- Rebidding the major suit does not show extra length. It shows a predefined side suit instead (not necessarily clubs).
- A low rebid (1NT or 2♣) becomes a relay:
- Extra length in the major suit is possible.
- Extra strength is possible.
- The relay can be non-forcing because many bids in this system are fairly limited.
