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 960 000 problems recorded in the main database "Echecs"
    • 11 reference tables: authors (more than 23 000), 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.
    • Queries.
  • Edition
    • each record, i.e. each problem, including diagram (using "1Echecs" font), author(s) name, source, solution, themes... can be recorded in a RTF file. Several problems can be recorded at the same time.
  • 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) i7-14700 CPU 2.10GHz with 64 GB memory, Windows 11 64-bits, using 24 threads out of 28:
         
        the following 8 is solved (key + variations with threats) in 1 s.
        Olivier SCHMITT, diagrammes 2009

        ‡8
        the following 11 is solved (key + variations with threats) in 3 minutes 07 s.
        Volker ZIPF, Problemschach 2009

        ‡11
        the following s9 is solved (key + variations) in 4 minutes 56 s.
        Udo DEGENER, Ceskoslovensky Šach 2006

        s‡9
        the following s=10 is solved (key + variations) in 5 s.
        Daniel PERONE, Ideal-Mate Review 2012

        s=10

      • more than 160 aims (mate, stalemate, capture, ideal mate, model pin mate ...)
      • more than 1300 fairy pieces
      • more than 1100 fairy conditions, on any (normal, cylinder or anchor-ring) board from 1×1 to 250×250.
      • and which is able to recognize a lot of themes
    • It is also possible to use the old "Chloe" programs (on 32-bits system), 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.
    • If you select a move in the solution, the corresponding position appears on the board.
    • It is possible to analyze orthodox studies or moremovers using a UCI engine (Houdini, Critter, Stockfish, Fruit, Rybka, Naum ...)
    • Some tutorials are available.
    • Statistics : number of problems by author, source, year ...
    • Possibility to save the diagram in PNG, BMP, GIF or JPEG format.
    • Possibility to regularly update the database "Echecs" (~ once a month).
    • Possibility to freely download new versions of WinChloe.
    • ...

WinChloe requires :

  • Windows 7, 8, 10 or 11.
  • Internet connection.
  • 1 GB disk space.

WinChloe light allows only to browse the main database, using eventually queries like in WinChloe. But it is not possible to record nor to solve problems. And the interface is only in French (help in English).

WinChloe costs 200 Euros.
WinChloe light costs 40 Euros
