WinChloe & WinChloe light

WinChloe is a software devoted to chess problems written by Christian Poisson.

Since version 2.00, WinChloe has a bilingual interface : French and English

Main features :

  • Database
    • More than 650 000 problems recorded in the main table "Echecs"
    • 11 reference tables : authors (more than 18 000), sources, themes, conditions ...etc.
      An Internet connection is needed to update these tables.
    • Possibility to record chessboards from 1×1 to 250×250.
    • Formatted solution.
    • Filters and queries.
  • Edition
    • each record, i.e. each problem, including diagram (using "1Echecs" font), author(s) name, source, solution, themes... can be copied to the clipboard in RTF format, then pasted in a text editor such Word. Several problems can be copied at the same time.
      Since version 2.00, the text can be automatically copied in "MS Word" and/or "OpenOffice.org Writer".
  • Solving
    • a new solving program which knows :
      • 20 stipulations (direct, help, self ...).
        Since version 3.09 : solving of orthodox direct and selfmates is much faster. Also, it is multithreaded and can use an external 64-bits engine.

        For instance, on Intel(R) Core(TM) (4 cores - 8 threads) i7-3770 CPU 3.40GHz with 8 GB memory, Windows 8 64-bits :
         
        the following ‡8 is solved (key + variations with threats) in 2 s.
        Olivier SCHMITT, diagrammes 2009

        ‡8
        the following ‡11 is solved (key + variations with threats) in 8 minutes 33 s.
        Volker ZIPF, Problemschach 2009

        ‡11
        the following s‡9 is solved (key + variations) in 13 minutes 29 s.
        Udo DEGENER, Ceskoslovensky Šach 2006

        s‡9
        the following s=10 is solved (key + variations) in 10 s.
        Daniel PERONE, Ideal-Mate Review 2012

        s=10

    • It is also possible to use the old "Chloe" programs, and Pascal Wassong's "Natch" for proof games.
    • Since version 3.05 : it is possible to solve studies if the corresponding Nalimov tablebases are installed.
  • Miscellaneous
    • "Redaction mode" : you play the moves on the diagram and they are automatically written in the solution.
    • It is possible to analyze orthodox studies or moremovers using a UCI engine (Houdini, Critter, Stockfish, Fruit, Rybka, Naum ...)
    • If you select a move in the solution, the corresponding position appears on the board.
    • Some tutorials are available.
    • Statistics : number of problems by author, source, year ...
