Conventions is the long awaited software which shows you how to use 90% of the conventions that can be found on the ACBL convention card. The software gives you a brief description of a convention and then lets you bid dozens of hands interactively with the computer. At each junction in the auction, you are given a choice of bids. One is right and the rest are wrong to some degree. Each choice is explained to show you what is good and what is not good about a bid.
