When 1s shows 8-17 as in the description, it makes no sense to jump with 9HCP.
This would imply that
1d 1s p 2d
p 2s
shows exactly 8HCP
I did not find any detailed description other than 2s shows below opening strength.
Maybe something like
2s = 8-11?
I agree. From GIBs definitions I have these possible bids for North
Note that 3S is forcing, and probably better than 4S
To show a medium hand GOB bids a trialbid
