Q-plus Bridge: Version 6

The following text contains a list of features of Q-plus Bridge 6, released in October 2000.
New features - compared to version 5.5 - are colored.
The text here can be only an overview. More infos are available through the tour; to get a more direct impression, you may also download a demo version.

Overview of development to version 6:

As in the previous years, more than half of the efforts has gone into improvements of bidding and play, resulting in an increased overall strength. A few features have been added, and some existing features have been arranged in a clearer way. Specifically, the general configuration dialog has been split into a separate player and scoring configuration, and saving of deals has been made more straightforward.
The total development time (since its start in 1990) is now approximately 9000 hours.

User Interface in General

- The Windows user interface is easy to handle, even for users with little experience with PCs.
  The careful display of cards and hidden cards, the suit and hand arrangements create a homely
  feeling for a bridge player.

- Context sensitive help texts are available with all screens.

- The product is shipped in a box with a printed manual.

Dealing & Deal Management

- A practically unlimited number of program dealt hands are available.
  These deals can be identified by a unique deal number.

- Own hands can be entered; they can be managed (saved and restored) within the program.

- Hands can be pretty-printed and exported to an HTML format which includes the graphical
  representation of the cards. Such hands in HTML format can be, for example, loaded into
  an editor, or used for web sites.

- Deals can be taken from deal files, both from self created files and from shipped deals
  from tournaments.

-  It is possible to enter remarks to the hands.

- The PBN-format (public bridge notation) is supported, both for importing and
  for exporting deals, making an exchange with deals from other sources easy.

- A deal filter can be used to select only interesting hands (e.g. strong South hands).


- Many bidding systems are shipped, which can be defined and modified using more
  than 150 treatments and conventions, which is done via an integrated convention editor.

- Help features during bidding:

  - Explanation and evaluation of the meaning of done bids.

  - Bidding list: Displays the meaning of the possible bids in a given situation.

  - Bidding warning: Warns the user if he is about to make a bid which is probably very wrong.

  - Bidding hint: Shows the bid which the program would select.


- Several playing strengths levels are available, for optimal use of the PC
   where Q-plus Bridge runs.

- Choices between several popular lead and signalling conventions are possible

- Help features during playing:

  - Display of the estimated probabilities of hidden cards.

  - Play warning: Warns the user if he is about to play a probably very weak card.

  - Playing hint: Shows the card which the program would select.

- The program does normally not cheat (i.e. does not look into the cards of the other players),
   but can be instructed to do so.

Scoring and Analyzing

- After a deal has been played...

   - its play can be reviewed trick by trick

   - it can be repeated by the program to compare its behaviour against that of the user.
      The repetition can cover both bidding and playing, or only playing.

- Scoring can be done either according the Rubber method, or IMPs, or Matchpoints.

- In conjunction with the shipped pair tournament data, a percentage score is calculated,
  which is a very interesting feedback for the performance of the user.

- Scoring results can be saved and restored for a later continuation.

Further Features

- Bids and played cards can be undone. The play can be completed by the program, if desired.
  The play can also be finished via a claim, the claim can be checked.

- A tournament mode is available, where the program knows only one hand.

- The CD contains Q-plus Bridge in three languages (English, French, German),
  which the user can switch.

- Q-plus Bridge can be played by two persons over a TCP/IP net or directly over a modem.

System requirements

The system requirements are:
- PC with a Pentium (or equivalent) processor.
- Operating system Windows 95, 98, NT4, 2000.
   (Note: Windows 3.1/3.11 cannot be supported anymore.)
- A CD drive is necessary for the installation.

Overall Strength

Q-plus Bridge is one of the leading programs concerning the bidding and playing strength. The overall performance in all the competitions of the last four years (Albuquerque 1997, Chicago 1998, Zia Match London 1999, Bermuda Jan. 2000, Maastricht Sep. 2000)  has been better than that of any other program.
