If DD analysis is on (check box is selected) - the DD tricks are displayed. The switch will also take place after clicking on the Double label.

If DD analysis is off - the SD1 tricks for first room or SD2 tricks for second room are displayed. Because Information obtained from opponents' auctions is also used, if the other side has bid, the number of SD tricks on both tables may be different.

By clicking on the table you can choose either SD1 tricks or SD2 tricks (the auction did not reveal the wrong location of the two missing kings).
