The workshop date has presented a comparison of two small defense systems available to the player No. 3 after intervention natural color of the player No. 2 and an opening 1NT's No. 1 player. The Lebensohl is the best known of the two systems. It is widespread and has enjoyed a greater distribution than Rubensohl. Without wishing to launder black one and the other, I would simply say that the Lebensohl is a coherent system that works well and easy to remember. The Rubensohl is a slightly more efficient because it allows to describe more accurately a larger number of types of hands. As such, it includes development and therefore requires more elaborate preparation work. It is therefore more suitable players to compete and regular partnerships. You will find here the 4 slides in PDF format summarizing defense systems against non-alerted the Counter (standard system and SOS which) and an outline of Lebensohl Rubensohl.Pour and further study, you will find here a file comprising an extract of an article by Alain Levy on Rubensohl and an excerpt from an article by Michel Bessis on these two conventions. Here is a link to the special folder Play Bridge on Rubensohl. . attached the drive 30.
good week all.
