These Practice pages can be utilized in several ways.
The recommended method is for two partners to be in vocal contact, each
looking at the page in a different computer - perhaps one with a laptop.
Using this method one partner would start by clicking on NORTH, the other on SOUTH.
Somewhat less satisfactorily, the partners can use a single computer, and alternate
looking at the display, again one as NORTH, the other as SOUTH.
As a last resort, one person can click back and forth between screens.
Start by clicking one of the buttons; when the bidding is complete click the BIDDING
button to check the "recommended" bidding.
