Do NOT COMPLICATE a SIMPLE game. 

A partership misunderstanding at the bidding stage invariably results in a zero.

Learn the basics of bidding*** - weak and strong opening bids plus the first response - and the rest is logic. Mental arithmetic mainly. Based on the principle that you need a minimum number of points for games and slams.

It then comes down to skill at playing the cards. And that is all about taking the logical route based on statistical probabilities.

It is not rocket science that the more complicated you make a bidding system, the greater the probability your partner will misinterpret one of your bids. Especially if you have to chop and change partners.

Whatever partner`s standard, if I play with someone for the first time, it is invariably "Back to basics". Keep it natural. Generally that means no Landi, Roudi, Mikhael, Lebensohl, Drury, no key cards et al. Usually it won`t stop us beating higher rated pairs and it won`t stop us bidding the slams as often as our peers. 

Instead of memorising the conventions, bridge students` time would be far better spent learning to do their sums. We all know that a vulnerable contract of 2 Spades + 2 scores 170 points. But I still can`t believe that the overwhelming majority of club players cannot calculate within a 30% margin of error that 2S vulnerable doubled plus two scores...1070. All very well doubling 2S to suggest you have four hearts but, if partner passes, the best card players in the world cannot avoid an unbeatable zero.
