ChessExplorer is a program intended mainly for solving typical chess problems: direct mates, selfmates, helpmates as well as seriesmovers.
He has additional options:
- creator of problems ( "Mate in 2", "Mate in 3", "Helpmate" and "Seriesmovers". )
- solving tasks of the kind "8-Queens Problem"
- counting the number of possible continuations from a given position in a specified number of moves.
The program is built according to the general principle that
absolutely all possible moves are tested and
all existing solutions are found exactly ("brute force" method - using large computing power of modern computers). The optimized algorithm allows a standard computer to analyze tens of millions of moves within a second (approximately 120 processor clock cycles per move).
Shareware - can be used within one month from the date of installation. If you use it after this date, the program must be registered (details in the "Info" option of the program and
here).
Characteristics:
- can find mates/selfmates/helpmates in any number of moves, up to 63
- preview and import/export FEN position ( *.pgn, *.epd, *.fen files )
- 17 notation's languages (Czech, Danish, Dutch, English, Estonian, Finnish, French, German, Hungarian, Icelandic, Italian, Norwegian, Polish, Portuguese, Romanian, Spanish, Swedish )
- "Men move" - select first move to test
- can stop and save the state of analysis in order to continue later
- show time, progress, number of testing moves and speed (moves per second)
- can move, rotate positions and print diagrams
- quickly installation, simple and intuitive usage.
Additional options:
- creating problems "Mate in 2" and "Mate in 3"
- counting amount of possible continuations from fixed position
- solving tasks of the kind "8-Queens Problem"
Solving problems.
Creating problems.
Option "Positions" ( "8-Queens non-attacked" ).
Option "Positions" ( "Maximum of attacking squares" ).
Remarks:
- The problems of kind "Mate in n moves" are well-known, but not everybody know what's "Selfmate" and "Helpmate":
- Selfmate - white moves first and force black to mate him (white)
- Helpmate - black moves first and helps white to mate him (black)
- Detailed descriptions of *.EPD, *.PGN, *.FEN files are in standard.txt (from http://pgn.freeservers.com). Compressed (38 kB) version of this file here. Description of FEN-notation is also in ChessExplorer (option "Info").
