-
- SYSTEM REQUIREMENTS
-
- MacChess 5.0.1 requires a Power Macintosh.
- (If you don't have a Power Macintosh, the non-Power Macintosh version,
- MacChess 2.5.1, is available from the downloads page at the Web site:
- http://members.aol.com/Macchess/ )
- MacChess has been tested on many Power Macs: 6100, 7300, 7600,
- and Power Macs with a 604e and G3 processor.
- Please let me know of any problems with other Power Macintosh models.
-
- MEMORY AND TRANSPOSITION TABLES
-
- MacChess requires about 4000 K, but wants more memory for
- “Transposition Tables.” MacChess uses transposition table sizes:
- 0.5 Mb, 1Mb, 2Mb, 4Mb, 8Mb, 16Mb, 32Mb and 64Mb.
- The "About MacChess" item in the Apple Menu shows the current table size.
- If you have lots of memory (RAM), you can use it to give MacChess larger
- transposition tables by using the Finder "Get Info" command in the
- File menu on the MacChess application file to increase the "Preferred Size"
- to the desired Transposition Table size plus 4000K.
-
- Generally, doubling transposition table size increases strength by
- roughly 8 rating points, and is most useful in the ending.
- MacChess test results suggest that a 4000Kb table is optimal for
- the middle game.
-
- Memory problems:
-
- If you are short on memory, reducing your screen color depth.
- (Using "256 color" instead of "thousands of colors" will
- reduce MacChess's memory requirements.)
-
- CASTLING
-
- Castling is a move of the king, not the rook.
- Just move the king two squares, and if castling is allowed,
- the rook will move by itself.
-
- OPENING BOOK
-
- The opening book version 5.0 contains 66,022 moves.
-
- =============================================================================
-
- WINDOWS
-
- When MacChess is launched, the chess board is in the upper left corner
- of the screen. There are five more windows:
-
- • Main Line: (Principal Variation)
-
- This shows the best continuation MacChess has found so far.
-
- • Info: Information about the search:
-
- - score: MacChess's evaluation of the position
-
- If the score is -M4 then MacChess can be checkmated in 4 moves.
- If the score is +90, then MacChess thinks it stands about a Pawn better.
-
- - depth/max.depth: Search depth so far, in normal and extended continuations.
-
- The first figure shows the search depth of MacChess and the second
- figure shows the highest search depth with extensions.
-
- - number of moves: Number of moves considered
- The second figure shows the number of moves minus the moves
- leading to a checkmate.
-
- - move/number:
- This shows the candidate move being considered.
- The number that follows indicates how many candidate moves have
- been considered at this search depth.
-
- - nodes: The number of nodes which are visited.
- A node is a possible future position that is examined.
-
- - nodes/sec: The number of nodes examined per second.
-
- - phase of the game:
- This shows what phase of the game MacChess thinks it is in:
- opening, middlegame or endgame.
- For example: KR-K indicates a King + Rook vs. King endgame.
-
- • Time:
- This window displays the clocks of white (left) and black (right).
- The times are displayed in hours:minutes:seconds format.
- For each player, it displays:
-
- Line 1: Time used so far (total, elapsed).
- Line 2: Time used on the latest move.
- Line 3: Time (average - per move) remaining before next time control.
- Line 4: Number of moves remaining until next time control.
- Line 5: Time remaining (total) until next time control.
-
- Above the clock display, the colors controlled by MacChess are shown:
- MacChess - Player,
- Player - MacChess,
- Player - Player, or
- MacChess - MacChess.
- (You can change "Player" to your name using "Options: Player Name ...")
-
- • Moves:
- The game score is displayed here.
- There are "VCR-style" control buttons on the bottom for controlling
- the monitor (game review) mode.
- The "VCR" buttons let you step through (>|) or animate (>) the game.
- To stop a game animation, click and hold on the pause (||) VCR button.
-
- • Opening Book:
- At program launch, this displays the version number and the number of
- opening book moves. During the game, the name of the opening played and
- the ECO code is shown here. The lower right corner of this window
- displays the move number where the game leaves MacChess's opening book.
-
- =============================================================================

- • Analyses:
- - Analyze MC Positions:
- This analyzes a series of positions and saves the results to disk.
-
- After selecting 'Analyze Positions' you progress through four dialog boxes:
- 1 - Set the time or depth to analyze each position
- 2 - Select the file that lists the position files (such as Serie CCR).
- 3 - Select the name of your output file.
- 4 - Confirm the information you have entered, and
- see how long the analysis will take.
-
- - Analyze EPD Positions:
- This does the same as Analyze Positions except it analyzes the
- positions stored in a file in .EPD format. Such files must be text files,
- and their names must end in .EPD. Of course, they must contain positions
- in proper .EPD format. Many such files are provided with MacChess.
-
- While MacChess is analyzing an Analysis Status window shows information
- about the test being run.
- For example, when testing a file of .EPD positions, it shows:
- - the name of the file
- - the "id" (identification field) and "bm" (best move) or
- "am" (move to avoid)
- - the number of the position being examined and the total number of
- positions in the file.
-
- - Analyze Game:
- This will analyze all or part of a game for white or black or
- both colors. The results are saved in a file.
-
- - Stop Analyzing:
- Exit the analysis session.
-
- - Analyze Player vs Player:
- This option puts MacChess in the player vs player mode and activates
- the search engine. So you can watch the search output while playing
- the moves yourself.
-
- - Log:
- This saves the search output to disk during a game. This will let you see
- what MacChess was thinking when you review the game later.

- ============================================================================
- Notes:
-
- 1) PGN is "Portable Game Notation,” and EPD is "Extended Position Notation.”
- These are standards respectively for storing games and positions so that
- other software can read them. The detailed description of the standard
- is at: ftp://caissa.onenet.net/pub/chess/PGN/Standard
- Many chess-playing programs and chess database programs support EPD and PGN.
- Thousands of PGN files can be found on the Internet - here are some sites:
- * 30,000 games from the last few years, arranged by opening:
- http://www.hsv.tis.net/chess/regence/regence.htm
- * Grandmaster tournament games from the current week (and prior weeks)
- http://www.chesscenter.com/twic/twic.html
- * Older games, collected by player name, and by event (over 250,000 games)
- http://www.pitt.edu/~schach
- MacChess reads the first 500 games in a PGN file. If there are more, split
- the file into chunks with 500 games or less with a text editor like
- BBEdit Lite.
-
- 2) "Permanent Brain" means the computer thinks on your time, that its "Brain"
- is "Permanently" active. If MacChess beats you all the time, you may want
- to turn this off, and give MacChess a short time to think in the "Level"
- menu. Giving MacChess a small time without turning off Permanent Brain has
- much less effect, since it thinks on your move. If it still wins too often,
- use the "Setup" option so that it starts the game without one of its pieces -
- such as a Queen ("Queen odds") or Rook ("Rook odds"). As you improve, you
- can move from Queen odds to Rook odds to Knight odds to Pawn odds.
- You can also make use of the "Easy" levels.
-

- found on the Web in the "Macintosh Chess FAQ" at:
