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

NORTH opens 2♣ and SOUTH responds 2 showing fewer than 8 points.

NORTH bids 2NT with a 23 point balanced hand.

SOUTH has enough points to bid 3NT, but with two 4-card Major suits bids 3♣ Stayman instead. NORTH won't confuse this as the second negative since that bid isn't used after a 2NT rebid.

So NORTH shows her 4-card suit and SOUTH bids 4.
