World Champion? What were the others like?,
This review is from: Jack - World Champion Computer Bridge (CD-ROM)
A bit like the parson's egg - good in parts, but frustrating.
I used to play bridge at county level some 30 years ago and thought it would be good to get some practice in before looking for a new human partner as I',m very rusty.
Jack knows about a lot of bidding systems and conventions, but only if you use them in the combinations it wants.
The bidding is erratic. With "Professor Jack" turned on it will force you into unmakeable contracts even if you try to bid the correct one (eg 5D-2 when 3NT makes).
Other times it underbids, for example leaving you in 6D when 7NT is stone cold.
Similarly, when it runs the hand for itself after you have done your bit, it will often do better then you simply by defending a lesser contract, for example you end up defending a slam which makes, Jack defends a game contract that makes with 3 over tricks then claims it's better than you when you actually managed to win one trick in defense and Jack did not.
I emailed their help line pointing out these inconsistencies and received the reply "I am sorry but we lack the time for discussing technical bridge related issues." Not what I would have expected, what are they there for?

Perhaps the bidding is out of sync with the system you are used to using - things have changed a lot in the last few years. The bidding may seem erratic but is linked to the convention card you have set up - whilst this is not as complex as some of us would like it does give a number of options and apart from some annoying missing extensions its not bad. Play one of the modern systems and it is right more often than not when one looks at the par scores, double dummy and possible outcomes.

Possibly but I've always played Benjaminised Acol, one of the systems offered by Jack. It does not seem to have changed much over the years.
