Bridge Craftwork DD

See where the tricks went. A browser extension that adds double-dummy review to the History panel of Bridge Base Online’s web client.

For every board you open

• The cards that cost a trick are marked in the hands, with the trick they were played to.
• Click one and the viewer steps to that trick. The hand that erred shows what it should have played: the best cards in green, the rest in red.
• The card that led and the card that won each trick are marked on the table.
• Each board in the list is tagged with the errors by you, your partner and the opponents, or “clean”. The event’s totals sit beside BBO’s own score.
• DD Details opens the board in the detailed double-dummy viewer, by way of Bridge Classroom.

On your device

The solver runs inside the extension. Nothing is sent to a server for analysis, unless you choose DD Details for a board. No analytics, no tracking, no accounts. Hide or show it any time from the menu on BBO’s deal view.
