It was a JOKE! It is virtually impossible to say anything about the merits of a double by running a simulation. A double dummy analysis tells you nothing because you need to take into account how the auction will develop if you double and how the auction will develop if you don't.
now isnt this what we are doing when we play bridge?
We assume when RHO opens he has min to max hcp, min spades suit.
so we let the constraints be set for RHO we have our hand and we let the computer deal the other 26 cars for our partner and LHO.
If we play in an ACBL tourney real live bridge, the hand records give us DF analysis of the possible contracts both directions. They do not take into account any auctions at all, it just looks at the hands and says what can me made in both directions. That bascially is what the computer assimilation is doing with Deep Finesse.
I am now up to 4349 hands that I have put through these constraints
