12.44 This new version of DDS includes many great improvements to the Filter feature, especially concerning Opening  Leads and DD Bidding. As always, the Filter feature works best when you have accumulated a large database of deals. The easiest way to get that large database is to open multiple files into one file: Click Open File, hold down the <Ctrl> key and click on all the files you want to include - typically they would be hands played by the same player.

This version has also been translated in Bulgarian. Thank you George.

Opening Leads

Here are some of the ways you can filter your results based upon the Opening Lead.

DD Bidding

Bridge players are aware of Double Dummy (DD) Play analysis on a hand, and also the concept of the "Par Result".  The key point is that DD analysis, unlike "real" bridge, makes its calculations after looking at all 52 cards. Despite the flaws of DD bridge, many feel that it can provide valuable insight into improving one's game.

Double Dummy Solver has taken this idea one step further by introducing the concept of DD Bidding analysis. Did we overbid, miss a sacrifice, or perhaps wrong-side a contract; i.e. declare from the wrong side of the table. This analysis is unaffected by the play of the hand.

Based upon the final contract and DD analysis, DDS classifies the bidding on every deal into 23 different categories, shown on the right.

The DD Bidding classification for each hand can be seen on the Scoreboard and also in the bottom-right corner of the main screen. More explanations about DD Bidding can be found in the User Guide.

Many thanks to Bob Cohen for all his tireless help in debugging this complicated feature.
