BriJ Conventions

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

    setting your bridge conventions

 The PRO version has a Define Bidding Conventions Wizard that lets you pick an overall style of bidding and allows you to 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.

You can also specify high card point ranges for opening bids like 1NT, 2NT and specify weak or strong 2-suit openers.

Aother 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.

You can adjust the point ranges in the PRO version of BriJ. For example where 1NT is given as 12-14 high card points, the range BriJ uses will depend on the overall convention you chose and any subsequent changes you have made to particular ranges. You can also turn off many of the conventions to suit your own bidding style.
