Stock Convention Cards

[Bbradley62]

Since players in MBC frequently claim to play "BBO 2/1", I was looking at the stock convention cards to see what this might mean.

 

According to the "BBO Advanced 1.3" convention card, over a 2♣ opening:

2♦: waiting

2♥: negative

2♠: heart positive

2NT: spade positive

3♣/3♦: natural positive

 

According to the "BBO Advanced (2/1 = GF)" convention card, over a 2♣ opening:

2♦: waiting

2♥: negative

2♠/3♣/3♦: natural positive

2NT: heart positive

 

Alternatively, according to the GIB 2/1 convention card, over a 2♣ opening:

2♦: waiting

2♥/2♠/3♣/3♦: natural positive

2NT: balanced positive

 

Is it deliberate on the part of BBO that these three are all different?

I think it's intentional. There's no point in having three identical stock CCs, IMO.
