The Best Bridge Program In The
World Champion Computer Bridge 2001, 2002, 2003, 2004, 2006
Jack is a computer bridge program developed by bridge
players for bridge players. One of the developers is former world champion
Berry Westra (Bermuda Bowl, Chile 1993). Jack uses state of the art computer
algorithms and is the current world champion of computer bridge. Jack's
possibilities exceed those of all other bridge playing programs. Besides its
exceptional bidding and playing strength, Jack offers a very user friendly
interface with many interesting features.
User Friendly Interface:
- The fully graphical user interface was developed by
bridge players for bridge players. Jack comes with a manual so you can sit down
and read about the most important features. Above that the program has a built
in interactive help with many examples. The tip of the day will help you master
Jack's possibilities faster.
- The program is very friendly. You can play with all cards
visible, take back cards or restart a deal at any time. Settings were not only
developed to change the appearance on your screen but also to adjust Jack's
behaviour. You can even set the tolerance with which Jack has to accept your
- After you completed a deal you can have Jack replay the
deal and instantly compare your result with Jack. You can store the bid and
play to look it over again at a later moment. Your own deal annotations can be
incorporated and stored with the deal in Jack.
- You decide if you want announcing bids and plays switched
on, in which case you'll hear the voice of Berry Westra.
Bidding and Play:
- The powerful deal profile allows you to generate deals
that meet certain criteria. Specifying for example auction, distributions,
combined values for North and South, playing tricks or points enables you to
create almost any situation. Very usefull for practising purposes.
- Deals can be printed directly to the printer or exported
to HTML files. You can specify in detail what to print (diagram, auction, play,
footnotes, alerts, annotations). The HTML- (internet-) format allows you to
directly bring the information online, look at it in your favorite browser,
email it to your partner or edit it with a word processor.
- Inputting a deal is very easy; have Jack show you how he
would have bid and played the deals from your local competition.
Extensive tournament environment with many tournaments.
Jack offers the functionality to create your own tournaments. Match Points,
imps, imp pairs and more. Just enter the number of rounds/contestants. Jack
will play the tournament for all participants whilst varying its play to
generate the necessary variation in the results. Also almost any PBN can be
converted to a tournament. The same tournament can be played by more than one
user. This enables you to compare with other people. Neat reports with
tournament results can be printed.
To start your own tournaments collection the CD
contains 25 tournaments (totalling over 100 sessions), in which you play
partnering Jack. These tournaments all appeared on Jack's website earlier. New
tournaments will continue to be made available in the future. For more
tournaments the Tournaments 2002 CD with annotated tournaments is on sale.
Extra for Jack 4 are the finals of the last six Worldchampionships Computer
Jack has a built-in virtual bridge club, the JackBridge
club, complete with promotion and demotion. You compete with Jack as your
partner amidst computer personalities. There are six different skill levels
(flights) and in a higher flight the computer players will be tougher to beat.
Of course you can specify the length of the competition, the strength of the
other players, and whether your opponents use their own convention cards or
yours. Your goal is to move up the ladder of skill levels. Try to become the
champion of the club!
Jack has a very extensive convention card environment.
Major convention cards from all around the world are built in, amongst others:
Standard American Yellow Card, Dutch Acol, 2/1 GF, Bridge World Standard, Jack
Verona (the exact card that was used in Verona 2006), Moscito (a strong club
system developed by the Australian international Paul Marston) and Jack's own
convention card. Of course convention cards for novices are available as well.
You can compose your own convention card using
adjustable conventions. Jack now has over 80 adjustable conventions including:
Variable 1NT, additional defences against 1NT, Puppet Stayman after 1NT. Many
other bidding additions as well, e.g. you can specify the style of overcalling
you would like Jack to use and it is possible to count an extra trump when
using RKC Blackwood).
Jack contains the fastest double dummy solver in the
world. Jack will instantly show you how many tricks can be made with each card.
Jack is completely multi-lingual, you can dynamically
switch between English, Dutch, French, German and Polish. Within any of the
supported languages you can also use the English, Dutch, French or German
playing cards. If your language is not supported yet, we offer the possibility
to translate the user interface.

both the 32 bit and 64 bit versions of those systems.
JACK RECAPTURES WORLD
TITLE - June 22, 2006
Of the seven teams that vied for the 2006 Computer Bridge
World Championship in Verona, Italy, June 17th through June 22nd, four emerged
from the qualifying round-robin (six 28-board matches. The Dutch program Jack,
seeking to regain the crown he had lost to the French program Wbridge5 in 2005
after winning the previous four championships, won all six of his round-robin
matches and led the field by a wide victory-point margin. The final standings
in the Round Robin: 1. Jack (Netherlands) 124 VP 2. Micro Bridge (Japan) 104 VP
3. WBridge5 (France) 102 VP 4. Q-Plus Bridge (Germany) 99 VP 5. Bridge Baron
(USA) 82 VP 6. Blue Chip Bridge (England) 66 VP 7. Shark Bridge (Denmark) 52 VP
In one 64-board semi-final match, Jack annihilated Q-Plus Bridge, 239 IMPs to
only 41. In the other semi-final, Micro Bridge edged defending champion
Wbridge5, 141 IMPs to 133. Both programs had improved substantially from last
year, but the highly enterprising style of Wbridge did not succeed against the
newly-aggressive Micro Bridge, which had switched from last year's four-card
major system to five-card majors. So as in Toronto, Canada, five years ago,
Jack faced Micro Bridge in the 64-board final. Jack had won easily enough in
2001, but in Verona he dominated Micro Bridge completely, winning 217 IMPs to

Jack Wins Computer
Jack (the Netherlands) retained its title of world computer
bridge champion, defeating last years finalist, Bridge Baron (USA),
157-97 in the 64- board final. Hans Kuijfs robot Jack, winner of the last
four annual championships, is on top of the computer bridge world.
PRESS RELEASE - JACK
RETAINS TITLE ONCE MORE
At the world computer bridge championships in New York City,
the Dutch program Jack once again defended his title successfully. After
winning in Toronto (2001), Montreal (2002) and Menton (2003), Jack was crowned
world champion for the fourth time. There can be no doubt that the brainchild
of Hans Kuijf is the strongest computer bridge player in the world.
The 'Jack Team' consists of Hans Kuijf, Wim Heemskerk,
Martin Pattenier and former Bermuda Bowl-winner Berry Westra. After Jack won
last year, they worked very hard to improve Jack even further, making the most
progress in the bidding. That turned out to be necessary, as rival programs
improved also. Almost all the programs use simulations and try to plan ahead.
However, this championship proved that Jack still has an edge over its
competitors. Defense is undoubtedly the weakest point of Jack's game. If he can
improve on that he will be very hard to beat in the coming years. More
information about Jack can be found at the website
