A while back I came across an Ace asking convention (documented by Ray Green) called Green Aces (GA) on http://www.bridgewebs.com/brunton/page16.html
I believe that GA is much superior to normal or kickback RKCB. The GA rules given in the above link are brief and I think need to be more expanded. However, I have embraced GA and played it in a few partnerships.
I have augmented the GA rules for my partnerships. I have also created a GA Style Exclusion Blackwood where any exclusion suit ask bid will never be higher than 5♦.
My purpose of this article is to understand why top level players have not been attracted to the GA convention?
I look forward to comments and discussions on GA.
