LH Green Card is for light opening. All 2
/2
/2
/2
openings are weak two bids.
And in the third position, 5 cards weak two bids are encouraged.
Another feature is the 1
/1
openings for the range of 11-14HP
(when 12-14HP range maybe 4+ cards or 11HP 5+ cards),
and the 1
opening only for those 11-14HP without a major suit or those hands minor suit much better than the major suit, such as 4 cards major with 6 cards minor or even 5 cards major with a 7 cards minor. This choice is very worth a try for experienced players.
Here is the brief description of the system and hope you enjoy it and take home master points with it.
