bocchi duboin are confiusing me

[Flame]

I watch their convention cards and they keep changing their mind about how to open GF hands, from 2000 to 2002 they played almost exactly the same as kalin-rumen from bulgaria and open 1c with the GF hands (RED system), but then in 2003 bermuda they changed it and opened a strong 2c (green system), the rest of the system had only minor changes (like passing 1c with 0-3 hcp), i wonder how they played at cavendish, is there a log for bidding ?

Bocchi Duboin have simplified their system greatly since 2001. They also believe in a lot of change as Bocchi gets bored.

It just seems wrong to play a system when you know someone very good played it and decided to change.

At Cavendish they played something similar to:

 

1♣ = 4+♣ or bal

1♦ = (4)5+♦

1M = 5+M

1NT = 12-14 or 15-17 (depending of position/vulnerability)

2♣ = 18-19 bal

2♦ = Any GF

2M = weak-2

2NT = 20-22 bal

 

Recenty they switched the 2♣/2♦ openings but I think the "Cavendish version" works better (18-19 balanced hand come more often so should be opened lower to keep all transfers).

 

The developent after 2♣ opening is something like:

2♦ = ♥transfer

2♥ = ♠transfer

2♠ = puppet to 2NT (placing contract or minor oriented hands)

2NT = ♣transfer

3♣ = ♦transfer

3♦ = Stayman

...etc.

 

This system works very well cause unloads the 1♣/1♦ openings and make the competitive bidding more accurate.
