BEGIN Notes:
Not satisfied with both windows and PM port of gnuchess 3.1 and my own
modification to gnuchess 4.0, which I added mouse support to move the
piece, I decided to port gnuchess 4.0 pl65 to OS/2 PM.
Start with Kent Cedola's code, here are what I did:
- Rewrote the most part of the main module (pmchess.c).
- Got gnuchess 4.0 chess engine work with PM GUI (hard part, to understand
someone else's thousands of lines of source code is not easy after all)
- Used Multithreaded programming technique (OS/2 programming is fun)
- Added continuously scalable board and piece (tricky)
- Redesigned menu logic
- Redesigned the pieces
- Implemented opening book to pmchess
- Added save, load and list game features
- Added language file to display some of information
- Added on-line help
- Fixed bugs caused by multi-threading (This is hard part, since GDB
doesn't do multi-thread debug)
- Fixed many other bugs (time consuming)
- Added STOP and REFRESH commands
I would like to thank Kent Cedola and Daryl Baker for their hard work
to convert GNU Chess from a character mode to a GUI world in the first
place. Without their effort, this work will take considerably long time.
Have fun with PMCHESS

>>> The PM version of GNUCHESS is a hard port of the Windows port done by
Daryl Baker. My goal was to do the initial port of the code to PM and
then hope that another programmer (someone that enjoys chess abit more
than I do) will continue with future enhancements. I myself prefer
games with lots of hexes.
While I did clean up some of the code when I did the translation. The
overall structure of this application needs some work. The board
should be moved to it's own window for example.
I would also like to thank Daryl Baker for his much harder task in
converting GNU Chess from a character mode to Windows in the first
place. Without his effort I would of never attempted the PM port.

Fixes/changes since 1.0
1) Fixed bug where "computer is black" never changed when switched
sides
2) Fixed problem with promoting pawn.
3) Changed File Get ... to File Open ...
4) Made fancier Open dialog box, (includes scroll bars amoung other)
5) Properly frees memory when program ends.
6) Made text color selectable
7) Added GNU copyleft to source files.
ToDos
1) Code needs to be looked over and cleaned up, routines
made "static near", and such. Maybe use -GW switch for
several modules.
2) Scalable/scrollable graphics (Probably won't get done)
3) Once pawn is promoted UNDO does not restore to pawn. This also
appers in the dos and unix versions of gnuchess. Not sure if
I'll fix it. I have tried not to change (this is debatable) the
orignal source except to "windowize" it.
release notes:
1) I have only tested this under windows 3.0 386 enhanced mode.
Seems to work ok in real mode though slower.
2) It requires at least 282k of memory.
3) Fits on a EGA screen, no scrolling implemented.
4) Most of the GNUCHESS commands are implemented.
5) When computer is playing itself abort by clicking on any square.
The last move made will most likely show "draw" or "mate", ignore
this message. You may have to remove the last move.
6) To have the computer think while it is your turn, select "easy"
from the menu. Clicking on square to take your turn will abort
the look ahead.
7) There is no help file.
8) The file gnuchess.boo must be in the same directory as
the executable.
9) The program create a file "chess.ini" in your windows directory to
store various settings. Currently only the screen colors.
Enjoy.
