Bocchi-Duboin:

 

2: waiting

2: 5+s

2NT: 5+s

3: 5+s

3: 5+s

 

In 04 and 05 was 3=6+s, 3=6+s

 

See also ETM Gold pages 30 and 92-93.

 

However do you perhaps mean 2 is strong, unlimited, and natural?

Yes I found Bocchi Duboin.

 

Curiously their card says for 2 that it shows a minimum of 2 diamonds. Does this mean that their game force is is based on a balanced hand at therefore that their 1-level openings are unlimited.

In Rosencranz' "Standard International" (anyone can feel free to correct this, I'm going on memory):

 

2 - 0-1 controls

2 - 2 controls

2N - 3 controls

3 - 4 controls

3 - 5+ controls

 

3 - Minimum 5-5 in majors

3 - Better 5-5 in the majors

3N - 7 card minor; 2 of top 3 honors (nothing else)

4/4 - 5M5M-3[m]

4M - 7 card major; 2 of top 3 (nothing else)

 

Schenken 2:

 

2 - no Aces

2, 2N, 3, 3 - That ace (NT = ). 3+ = That ace + one higher (I think)

 

The next suit scans for Kings, and then Q's.

Standard french bidding over 2 GH is along these lines :

- 2 no Ace

- 2 Ace of Heart or Spade

- 2NT 8+ HCP

- 3 Ace of club

- 3 A of Diamond

-3 through 3NT 2 aces (same color, rank, mixed)

 

some variation aound that scheme exist but do not think there are a big improvement; think you strike gold every three year or so but otherwise the approach is flawed (no to mention it requires a lot of work to deal with subsequent bidding for something which happens very rarely)
