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.
 Bid this hand with your partner.
 The opponents do not bid.

NORTH has a balanced hand with 11 points, so she responds 2NT to SOUTH's 2♣ opening bid.

SOUTH bids 3NT. This shows 22-24 points, a hand he was planning to rebid 2NT.

NORTH knows the side has at least 33 points, but no more than 35 so she bids 6NT.
