It holds 50,000 random deals – a compromise number giving acceptable search times and acceptably varied deals. For each deal, information is noted about the cards dealt to each seat, the joint holding of each pair and the deal overall. Sets of deals can be selected on any or all of the three.
|High card points||Sum of A=4, K=3, Q=2, J=1||Sum of hcp of the two seats||Difference between the hcp totals of the two pairs|
|Length points||One point for the fifth and subsequent card(s) in each suit.||Sum of lep of the two seats||N/A|
|Losing trick count||Count of missing AKQs for each suit, mitigated by suit length.||Sum of ltc of the two seats||Difference between the ltc totals of the two pairs|
|Balanced||0 = the hand is unbalanced
1 = the hand is balanced i.e. no singleton or void and no more than one doubleton.
|The number of balanced hands in the pair||The number of balanced hands in the deal|
|Shape||The no. of cards in each suit, longest first e.g. 5-3-3-2. Actual suits are not indicated.||N/A||N/A|
|Fit||N/A||0 = the pair have no fit
1 = the pair hold 8 cards or more in one or more suits
|The number of pairs with a fit.|
|Controls||N/A||f dash s where f is the number of suits with first round control and s the number with second round control.||N/A|
Deals in the database were generated randomly and the randomiser is pretty good. In high-volume tests, results conformed closely with predicted distributions. With our 50,000 deals, expect only minor anomolies.
From time to time, the database will be refreshed i.e. deleted and re-spun with new, random deals. This will prevent over familiarisation with its deals - particularly the low probability, extreme distributions so often re-visited.
