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.

SOUTH might be tempted to blast into Blackwood with his first bid, pushing toward some slam in s. He chooses to temporize with a 1 response and is rewarded when NORTH jumps to 2NT (18-19 points).

The Notrump bid prevents SOUTH from using Blackwood, but Gerber 4♣ will work just fine. When he discovers that NORTH holds three Aces and one King he can count thirteen tricks.
