There are many software that show best line of play double dummy, knowing all 4 hands. But not one that will conclusively show best percentage line of play for knowing only two hands, single dummy. The various playing software out there, like Jack, Wbridge, GIB, will give you opinion if you make them play the hand. They are often pretty good about this if they aren't confused by the auction, but won't be as good as say a Michael Rosenberg at drawing inferences about human defenders and finding good psychological plays that may not be the best technical play but will be successful in practice more often vs typical defenders.

Agree with Stephen Tu.

The current spurt of progress in AI might change things. In particular, the emergence of Deepmind type neural-net AI, running on dedicated hardware like Google "tensor-processors".

Given the basic rules of a game (in this case the subset applying to disclosure and declarer-play), Deepmind bots can learn, by trial and error, playing against themselves, without further human input. With improved disclosure, augmented where necessary by GIB-type simulation, IMO, such bots would approach declarer-play perfection. Of course, they would still be susceptible to bad luck

Just as the Robos have limitations as ican’t read the human mind so will be the case with a software.As far as dummy play is concerned there are a few excellent books available and some out of print..Double dummy analysis is also available in some books but I think that that is the limit to books..I ,personally,do not think that such a software will or can be developed.
