- New in MacChess 4.0 Rotterdam December 1997
-
- First, a special "thank you" to Richard A. Fowell.
- He helped test MacChess 4.0 and proofread my English.
-
- Special thanks also to everyone that gave me support and advice by
- sending me postcards and email.
-
- ====== NEW FEATURES ======
-
- 1. Save Game As (File menu) "Save" now overwrites file!
- 2. Player Name (Option menu) Enter and/or save player name.
- 3. Next Best Move (Option menu) Not just "2nd best" now.
- 4. Analyze Game (Analyses menu) Annotates an entire game
- 5. Analyze Player vs Player (Analyses menu) Displays analysis as you move
- 6. Works in the background
-
- 7. Copy and Paste:
- - PGN game ( when the Moves window is active. )
- - EPD position ( when the Board window is active. )
- - Principal variation ( when the PV window is active. )
-
- 8. Changed the import PGN window so that you can choose several games
- out of a game file without reading the all the games every time again.
- 9. Player names from imported PGN games are displayed above the board.
- 10. More knowledge of simple endings was added to the chess engine.
- 11. ECO codes are now displayed as will as opening names.
- 12. Added nearly 8,000 moves to the opening book.
- 13. MacChess web site created by Richard A. Fowell
-
-
- ====== FIXED PROBLEMS ======
-
- 1. Easy Level settings are now:
- - Saved with the game.
- - Saved with the "Save Level Settings" option from the "Level" menu.
- 2. A saved game as Player vs Player will be loaded as Player vs Player.
- 3. Play command[G]: (Players menu) Now this also works in the
- Player vs Player mode.
- 4. Can make a move after closing a window. With MacChess 3.0 it was not
- possible to make a move after a window was closed. This could be
- fixed by clicking on a non-board window, then clicking on the board
- window again.
-
- ====== SAVE GAME AS ====== ( Important Change! "Save Game" now overwrites!)
-
- The "Save Game" command in MacChess 2.5/3.0 always prompted for a file name -
- it really was a "Save Game As" command. This was nonstandard, and awkward
- when using Macchess to track postal games. If you load a MacChess game into
- MacChess 4.0, make some moves, then select "Save Game", you will not be
- prompted - the current game will overwrite the game you loaded.
-
- It is very important that you understand this, because if you are used to
- the old behavior, you may overwrite a game that you did not want changed!
-
- *** If you want to save to a new file, ***
- *** you must use the new "Save Game As" command. ***
-
- ====== PLAYER NAME ======
-
- The "Player Name ..." command in the Option menu lets you fill in
- and save a player's name. The first eight letters of that name will
- be replace the default text string "Player" as MacChess's opponent.
-
- ====== NEXT BEST MOVE ======
-
- The "Next Best Move" in MacChess 3.0 was really only "Second Best Move" -
- no matter how many times you invoked it, only one move was excluded
- from the candidate move list.
-
- The "Next Best Move" command from the Option menu now excludes another
- move from the candidate move list each time it is used, until no moves
- are left.
-
- ====== ANALYZE GAME ======
-
- The "Analyze Game" command in the Analyses menu analyzes a specified
- range of moves in a game for a specified number of seconds per move
- for the white moves, black moves, or both.
-
- The results are saved in a file. This is an excellent way to have
- MacChess annotate one of your tournament games overnight.
-
- ====== ANALYZE PLAYER VS PLAYER ======
-
- The "Analyze Player vs Player" command in the Analyses menu puts
- MacChess in the "Player vs Player" mode and activates the search engine.
- So you can view the search output while playing the moves yourself.
- This is a good way to play over a move from a book while getting
- a continuous analysis from MacChess.
-
- Currently, you must make the moves by hand - you cannot use this
- feature to have MacChess analyze while using the "VCR buttons" to play
- through an existing game.
-
- ====== WORKING IN THE BACKGROUND ======
-
- Now MacChess continues analyzing when you put it in the background.
- This lets you use your computer for other tasks while MacChess is
- doing a long analysis like "Analyze Game".
-
- However, this can slow down your other work considerably!
-
- If you want MacChess to stay open in the background, but do not want
- it to think, make sure MacChess is in "Player vs. Player" mode,
- with "Analyze Player vs Player" off before sending MacChess to the back.
-
- ====== COPY AND PASTE ======
-
- The "Copy" and "Paste" options in the "Edit Menu" can now used by
- MacChess in a restricted way for:
-
- - PGN games
- - EPD positions
- - Principal Variation (PV)
-
- as follows:
-
- - A PGN game is copied/pasted by making the Moves window active. Then
-
- - Copy: copies from the "Moves" window to the Clipboard.
- - Paste: pastes from the Clipboard to the "Moves" window
-
- - An EPD position is copied/pasted by making the Board window active. Then
-
- - Copy: copies from the "Board" window to the Clipboard
- - Paste: pastes from the "Clipboard" to the "Board" window
-
- - A principal variation (PV) is copied by making the PV window active. Then
- - Copy: copies the principal variation as one text line to the Clipboard.
-
- ====== IMPORT PGN ======
-
- The import PGN window was changed so you can view several games from a PGN
- file without reloading the PGN file each time.
-
- The import PGN window is sent to the back after a PGN game is chosen.
-
- To view another game from the same PGN file:
- - click on the Import PGN window to bring it to the front
- - select another game from the window.
-
- To open a new PGN file
- - click on the Import PGN window to bring it to the front
- - close the Import PGN window
- - use the "Import PGN" menu item to read in a new PGN file.
-
- Another new feature is that the names of the players from a imported
- PGN game are displayed in the Board window bar.
-
- ====== END GAME KNOWLEDGE ======
-
- I've added some simple endgame knowledge to the search engine.
- It is far from complete but the method can be used
- to add much more detailed endgame knowledge in the future.
- (Thanks to Walter Ravenek, author of Arthur, who shared his ideas with me)
-
- The knowledge of draw, win or loss are added for some end game positions
- with the following pieces.
-
- - K-K
- - KN-K/ KNN-K
- - KB-K/ KBB-K
- - K-KN/ K-KNN
- - K-KB/ K-KBB
- - KN-KN/ KNN-KN
- - KN-KNN/ KNN-KNN
- - KB-KB
- - KB-KN/ KB-KNN
- - KN-KB/ KNN-KB
- - KP-K
- - K-KP
- - KP-KP
- - KBP-K
- - K-KBP
- - KNP-K
- - K-KNP
- - KR-K
- - KQ-K
- - K-KR
- - K-KQ
-
- ====== OPENING BOOK ======
-
- ECO codes were added to the existing opening names in the MacChess
- opening book. The sub-variations are far from complete
- but will be expanded in the future.
-
- I added nearly 8,000 moves to the opening book - now 54,045 moves.
-
- ====== MACCHESS WEB SITE ======
-
- There is a MacChess Web site, designed by Richard A. Fowell, at:
- http://members.aol.com/Macchess/
