Bridge Craftwork DD

Double-dummy review in Bridge Base Online's History panel: every card that cost a trick, and what should have been played instead.

See where the tricks went. Bridge Craftwork DD adds double-dummy review to the History panel of Bridge Base Online's web client, right where you already look back over your boards. Open an event in BBO's History and, 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 double-dummy best cards in green, the rest in red. • On the table, the card that led and the card that won each trick are marked, since the hands no longer say who won the trick before. • 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. • A DD Details button opens the board in the detailed double-dummy viewer, by way of Bridge Classroom. The double-dummy solver runs inside the extension, on your device. Nothing is sent to a server for analysis, and the extension makes no requests of its own to Bridge Base: it reads the boards BBO's own History panel has already loaded. Analyses are kept on your device for 14 days, so going back to an event is instant. Hide or show it any time from the menu on BBO's deal view. No analytics, no tracking, no accounts. Open source.
