Upgrade History - Current version 2.0.2.1

====================

NEWS:

Bridge Analyser uses a double dummy solver about 10 times quicker than Deep Finesse and the current version has multi-processor support - a typical 32 hand duplicate set of boards will be fully processed with double dummy results for 0-13 tricks in all 20 contracts in under 20 seconds on a modern computer with one processor, under 10 seconds with two processors and in a blistering 5 seconds with 4 processors. Dealing also supports multi processor systems so a large number of deals with complex biasing can be created in parallel on each processor.

If you would like to see any new features email me and I will look at including them in the next release.

Bridge analyser is the ideal bridge software for Bridge Clubs, Bridge Teachers and players interested in developing their bidding, play or defensive skills.

Compatibility Info: I have now updated all my code to work with new Windows 10, Windows 8 and Windows 7 security requirements, either 32bit or 64 bit versions. An unfortunate side effect is that it now only works with Windows XP or later. (Windows 2000 and earlier will show an error and probably not start, although some server versions will work). If you have a multi core processor it will run using 2 cores on quite low RAM but to use more than 2 cores at once the min RAM requirements are:

> 1Gb to use more than 2 cores at once;

> 2Gb to use more than 4;

> 3Gb to use more than 8 (max = 16 regardless of RAM).

I have not tested it with any other operating system though I know of no reason why it should not work with other systems that have Windows Emulation and I know of users running it on a Mac with Windows VM.

Upgrade:

Note upgrades are always free but I charge a nominal £10 for a new serial number when you get a new computer. I think this is fair as you would normally expect several free upgrades between computer changes.

  • Reworked the user interface to use skins and allow buttons on the caption bar to restore the functionality lost when Microsoft disabled caption bar buttons in Windows Vista.
  • New double dummy option to compare IMP and MP scores for 2 contracts.
  • Added ability to export single deal printouts to a Word document (requires Word to be installed on your computer).
  • A few small tweaks to various menu options.

Help file updated.

v1.1.0.1 Launched 24th October 2009:
  • Minor error in menu draw routine corrected
  • Minor error corrected so that if a file containing makeable contracts data is dropped into Bridge Analyser the window hides the unnecessary 'get makeable contracts data' button.
v1.1.0.0 Launched 22nd October 2009:
  • Major new code to switch from the Deep Finesse double dummy solver to Bo Haglund's solver which is much faster. This has dramatically improved the speed of double dummy analysis and analysing sets of hands for makeable contracts.
  • Added a database save option so all sets of hands dealt for duplicates or competitions can be saved to the database (file name HandDatabase.mdb) and retrieved later. ·
  • Added a deal ID code for each set of deals saved and printed.
  • Option to calculate lifetime statistics for all deals in the database file.
  • Added 'par result' to summary print out and makeable contracts display on the main screen.
  • Made the routines for fixing cards in any hand more flexible so you no longer have to do it in a specified order.
  • Minor change to saved bdg files which now store makeable tricks (ie 0-13) rather than makeable contracts (ie - or 1-7). As a result you can now always toggle between tricks and contract view. Opening an old file will cause the Makeable contracts data to be removed so you will have to run the DD solver again.
  • Bug Fix: various issues related to Windows Vista have now been resolved (except one solved in v1.1.1) so you can run the program in normal mode rather than as Administrator.
v1.0.8.0 Launched 13th September 2009:
  • Major new code to add overcall bidding options to the bias menu.
  • Reworked the look of the bias form windows and the bid system form windows to simplify editing settings.

  • Added a 'make declarer South' option for printing hands that have been bid to a final contract for lessons.
  • Added option to select which hands are printed (used to be all, NS or EW).
  • Added option to save the screen form to a jpg picture file.
  • View menu item added to give more option on which hands are shown on the screen.
  • Some cosmetic changes made to the look and feel of some windows.
  • Bug on startup fixed so last used bidding system is correctly read.
Help file updated.
v1.0.7.1 Launched 28th January 2009:
  • Fixed a bug printing curtain cards.
v1.0.7.0 Launched 10th July 2008:
  • Major rework of the look and feel of the menus and buttons using Windows Themes so the look of the program should match any decisions you make in the look of Windows.
  • Added option so Deep Finesse can show the number of overtricks or undertricks for any card when in play mode as well as whether any card is a good or bad play.
  • Added play option in which Deep Finesse can be set to play or defend double dummy whilst you play or defend with the hand you choose. This is very much experimental at this stage and DF will often play a card that makes your life easy if it can see the triple squeeze must work ! I need to work on how to make the play more deceptive.
  • Bug fixed where open file may fail after a certain sequence of dealing & save.
  • Added file registration option to the menu so you can automatically associate Bridge analyser files with the program. If you enable this clicking a BA file in windows explorer will open the file and the BA software.
  • Added some sizing routines to solve issues for those using non-standard screen DPI settings.
  • Added an indication of total hands dealt to the graph and Double Dummy screens so you can see how many deals were needed to find those analysed that met the bias settings you used.
  • Some menu layouts changed.
v1.0.6.1 Launched 30th September 2007:
  • User created files that were stored in the Program Folders (usually C:\Program Files\Bridge Analyser and its Saved Files sub folder) have been moved to the all users application files area (normally C:\Documents and Settings\All Users\Application Data\Bridge Analyser). This is because Microsoft are putting restrictions on writing data to Program Folders as a security measure. If you upgrade Bridge Analyser it will move the files it created on first startup (so you will keep any changes you made to them) but you have to manually move any files you have created such as .bdg & .b13 files and your bidding system files.
  • The .bdg & .b13 file structures used by Bridge Analyser has been changed to allow Deep Finesse results to be stored. If you try and open an old format file it will be copied to a new file (it will be named 'oldname.old') and a file containing all the deals in the new format will be created in its place.
  • The help files have been updated and changed to html format as Microsoft are no longer supporting the old format I originally used.
  • You can drag & drop .bdg & .b13 files onto the main BA screen or the open file screen
  • The file open menu lets you open PBN files directly and saves a copy in .bdg format automatically
  • You can now save directly in PBN format rather than save as .bdg and later convert the file to PBN
  • Double Dummy analysis will save Deep Finesse data if you select the option to save the run as a file
  • a screen drawing bug that came to light after a recent Windows update has been corrected (sometimes the main screen was showing the heart 2 repeated 13 times in a hand after opening and closing the DF window).
v1.0.5.0 Launched 10th December2006:
  • Added option to set Deep Finesse to analyse for all tricks from 0 to 13 rather than just whether a contract can be made. This affects output for Double Dummy analysis and also for single hand analysis from the main screen but not printed output for hand records which stay as before.
  • Corrected a bug where putting a partly fixed hand in a position other than South, then setting a constraint for another hand that the partly fixed hand also complies with could result in a deal passing a bias test when one hand does not meet the tests set
v1.0.4.0 Launched 2nd July 2006:
  • Corrected bug that prevented user from stopping a Deep Finesse analysis when impossible hand constraints had been set
  • Added ability to import a saved hand to any position (N, S, E or W rather than just South)
v1.0.3.0 Launched 22nd September 2005:
  • Improved graph utilities to include:
    - Filter option added so graphs can be redrawn excluding or including hands with certain suit length/strength/shape/opening bid characteristics
    - Ability to choose your own axis values for points graph (incl. 1 point ranges)
    - Standard deviation is displayed when graph bars are clicked, and bid system info is shown when clicking on the opening bid graph
    - Export graph data and/or underlying base data to an Excel spreadsheet
    - Graphs can now be drawn for any of the four hands
    - Graphs can analyse hand data stored in a file rather than just new deal sets
    - Number of aces held added to one of the graph pages
  • double dummy analysis enhanced
  • Average number of tricks now displayed for each contract
  • Deals used can now be saved as a file and reviewed later
  • Curtain card creation now has a more conspicuous warning if the deal mode is not random, and sets Deep Finesse to analyse all contracts (in case you set it differently in Double Dummy analysis)
  • Ability to edit partly played hands added to Hand Report function
  • Multi 2D bidding revised to avoid a bug if certain other conventions were set with it
  • Option to check for free program updates added to help menu
  • Option to create start menu group added to help menu
v1.0.2.0 Launched 26th August 2005:
  • Improved double dummy analysis to allow the same contract to be analysed for several different leads at once
  • Added ability to export double dummy results and probability tables to Excel
  • Added progress bar to form dealing sets of hands
  • Added menu item under Swap Dlr/suits to move cards between hands on the main form
  • Corrected a bug that prevented lead of a 2 in double dummy analysis
  • Corrected a bug that prevented hand save without bidding
  • Added ability to close any window from the system menu 'X'
HELP files also upgraded to v1.0.2.0 at this time
v1.0.1.0 Launched 28th July 2005:
  • Added ability to select a forced lead in double dummy analysis
  • Added ability to define overall hand shape in bias deal options
