IMO,there are 3 parts on bridge playing,bidding,defence & declarer playing.To most players other than true world class,they should be evaluated by at least 3 corresponding committee consisted of certified teachers. Any member would apply for a test(match) on bidding,defence or declarer playing,then their grades are definite. That's for BBO on-line ranking system.

I don't think I know whether 5!S dbl will be down,but I think my PD knows more than I.

I'll play a type of negative dbl,for a higher suit and some HCPs.

I've discovered an old convention(named Becker,attributed to Mr. R. Jay Becker) partial same to this new one. The link is: http:www.bridgeguys.com/Conventions/Becker.html
