BJ Bridge for Android

BriJ Conventions

In BJ Bridge PRO, there is a choice of bidding systems

    setting your bridge conventions

Select the basis for your system from this table.

The free product Duplicate Bridge Beginner uses the Beginner Acol basis. The free BriJ Lite uses the Standard Benji basis

  Acol Benji Acol SAYC
Beginner Beginner Acol basis   Beginner SAYC basis
Standard Standard Acol basis Standard Benji basis Standard SAYC basis
Advanced Advanced Acol basis Advanced Benji basis Advanced SAYC basis

The PRO version has a Define Bidding Conventions Wizard that lets you pick an overall style of bidding. (The basis from this table). Then you can choose which particular conventions you want to adopt or reject, from the list below. For example, you can add 5-card majors to standard Acol if you wish.

At any time later, you can go back to Define Conventions to change either the basis system or individualo conventions selected.

You can also specify high card point ranges for opening bids like 1NT, 2NT and specify weak or strong 2-suit openers. For example, if a system normally has 1NT  given as 12-14 high card points, the range BriJ uses will depend on any subsequent changes you have made to particular ranges.

You can turn off many of the conventions to suit your own bidding style.

Currently (April 2015), BriJ users have chosen a mix of basis conventions with this distribution:

Bidding Systems

Another PRO feature offers a choice of settings for an Aggression Level. This controls the bidding style in a contested auction. High 'aggression' effectively inflates points and reduces losing trick count (after a suit fit has been found) when it's advantageous. The reasons might be either to stay in the auction or to get in the way of opponents bidding. Set the level LOW for minimum adjustment to points and losing trick count, probably sensible if you're a beginner. HIGH makes the bidding more interesting, MEDIUM somewhere in between.

Note: Benjaminised Standard English Acol is the bidding system used in the free version of BJ Bridge. It offers a limited set of bidding facilities that you cannot alter. For example you cannot turn off the two-suited overcall conventions or turn on the 5-card majors or Gerber bidding conventions in the free version.
