Lead Captain generates
millions of totally random hands to find hands that fit
your criteria, then uses double dummy analysis to
determine the results of those hands. The better you have
defined the hand patterns that fit your problem, the
better your results. Generally 2,000 or more hands are
needed to obtain statistically meaningful answers. Whether
you are trying to answer an opening
question or a
, the general procedure with Lead
Captain is the same:
- Fill in all 13 cards for the South hand. In bidding
decisions, you can also define a pattern for South in
lieu of all 13 cards.
- Define the other three hands. Up to 50 different
patterns are allowed for each hand.
- Fill in the desired number of deals in your study.
- Click the Leads or the Create Deals button.
When you click the Create Deals button, Lead Captain
shuffles, deals, and then determines if the criteria
you've set for all hands have been met. If not, the
cards are randomly shuffled again and the resulting deal
If the deal meets all hand definitions Lead Captain
then uses Bo Haglund's double dummy engine to determine
the optimum double dummy result, stores that information
for subsequent reporting, and then returns to shuffle
the cards once again.
In a simple test, Lead Captain my shuffle the deck one
million times to find 5,000 hands that fit your
definitions. Depending on the number of patterns to be
tested, it takes approximately 10 seconds for Lead
Captain to shuffle and deal 1 million hands. It takes
the double dummy engine roughly two minutes to make it's
calculations on those 5,000 hands.
