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.

SOUTH has a balanced hand with 23 points. He opens 2♣ and expects to rebid 2NT.

NORTH has 12 points so makes a positive response in her best suit. Since that suit is s she must jump to the 3-level.

SOUTH now describes his balanced, minimum hand by bidding 3NT.

NORTH bids 6NT, knowing that the partnership holds at least 34 points.
