dokoko Posted June 23, 2017 Report Share Posted June 23, 2017 I recently read the Bird/Anthias books on opening leads (review). Although tbh DD analysis proofs nothing, I like the ideas and want to do some research on the subject. Is there any useful free software available to generate deals which match a given bidding and analyze them on double dummy basis (like that used by the authors)? Thanks for your help.

barmar Posted June 23, 2017 Report Share Posted June 23, 2017 There's Henk Uijterwaal's Dealer software: https://henku.home.xs4all.nl/software/dealer.html You don't give it the bidding, you give it a description of the hands (HCP, distribution). So you need to translate the auction to the types of hands that would fit. This is the software we use when you specify hand criteria in BBO's Bidding Practice tables.

johnu Posted June 23, 2017 Report Share Posted June 23, 2017 I use Dealmaster Pro, http://dealmaster.com/ You can either input specific hands, or specify point counts, suit quality, distribution, or a combination of both in a simulation. It runs a double dummy analyzer that gives expected number of tricks, and can also determine which card is the best lead. Quote Link to comment Share on other sites More sharing options...
uday Posted June 25, 2017 Report Share Posted June 25, 2017 This is a version of the usual BBO dealer tool, but one that supports the tricks( ) function, allowing you to do some of what you're talking about . You have to specify the constraints for the unseen hands so it is a bit more work than "auction went: 1n p 3N" http://dealergib1.bridgebase.com/tools/dealer/dealer.php You can try it w/this input to see how many times you'd take 10 tricks in spades under specific circumstances predeal north SKQT32,H2,DQ32,CQ432 s = shape(south,4x5x) and hcp(south) >= 11 and hcp(south) <= 12w = hearts(west) ==5 and hcp(west) >= 13 e = hearts(east) >=3 and hearts(east) <= 4 and hcp(east) >= 6 condition s and w and e produce 10 action frequency "Game in spades" (tricks(north,spades)>=10, 0, 1) Quote Link to comment Share on other sites More sharing options...
nige1 Posted June 25, 2017 Report Share Posted June 25, 2017 Thank you, Uday. Just what I always wanted. A simple dealer script: # # Dealer Script print dealss and how many tricks NS make at double-dummy. # Uses Dealer by Hans van Staveren et al. # http://dealergib1.bridgebase.com/tools/dealer/dealer.php # produce 5 condition hcp (north) > 13 and spades (south) > 4 action printoneline (tricks (north, spades)) Which produced this output: n KQ.5.QT9.AKJ8743 e 63.A9843.8753.QT s T9852.QJT2.KJ6.2 w AJ74.K76.A42.965 8 n K9.K942.AJ8.AJT5 e A62.JT83.K972.43 s J8743.6.Q6543.97 w QT5.AQ75.T.KQ862 7 n QT852.5.AKT3.AQ2 e K.AKT863.964.T54 s J7643.7.QJ52.J86 w A9.QJ942.87.K973 9 n A976.KQT8.A7.QT3 e Q8.J2.K954.A9652 s JT532.54.QJ3.J84 w K4.A9763.T862.K7 7 n KQ9.942.KJ98.AK9 e 2.KQT85.A732.J32 s AT763.J.Q64.QT86 w J854.A763.T5.754 10 Generated 95 hands Produced 5 hands Initial random seed 1498414231 Time needed 0.439 sec Quote Link to comment Share on other sites More sharing options...
Lorne50 Posted May 10, 2021 Report Share Posted May 10, 2021 I recently read the Bird/Anthias books on opening leads (review). Although tbh DD analysis proofs nothing, I like the ideas and want to do some research on the subject. Is there any useful free software available to generate deals which match a given bidding and analyze them on double dummy basis (like that used by the authors)? Thanks for your help. You could try Bridge Analyser here:https://www.cantab.net/users/bridge.analyser/Bridge/index.html It is mentioned in the book and was used by Taf Anthias for some of the initial analysis. Amongst other things it can deal hands to match constraints you set and do double dummy analysis based of fixed leads. Quote Link to comment Share on other sites More sharing options...
