For example, the image shown below is taken from the bridgewebs.com website that provides results of events at my local bridge club. At lower right is a summary of what can be made in each strain by the different declarers. I have also seen analyses that show “par” for each deal, taking into account contracts that go down doubled.
I don’t suggest that the current GIB Double Dummy feature be dropped – it is very useful indeed. But a full deal double dummy feature would be a great addition.
