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.
 Your partner, SOUTH, is the Dealer.
 Bid this hand together.
 The opponents do not bid.
 You are the Dealer.

NORTH has 5 points, so she responds 2 to SOUTH's opening 2♣ bid.

SOUTH bids his 5-card ♠ suit.

NORTH is too good for the second negative, so she supports SOUTH's ♠.

SOUTH doesn't have enough to think about slam, so he signs off at 4♠.
