MacChess 2.5 Manual   by Wim van Beusekom             Rotterdam June 1996

MacChess 2.5 is Freeware (postcardware) and consists of five files:
the application file, a data file, and three text files:

- MacChess 2.5 program; 495,375 bytes.
- MacChess Opening Book; MacChess 2.5 document 136,526 bytes.

- ~Manual MacChess 2.5; SimpleText document 12,077 bytes.
- ~History of MacChess; SimpleText document 4,016 bytes.
- ~New in MacChess 2.5; SimpleText document 8,708 bytes.

SYSTEM REQUIREMENTS

MacChess requires a Macintosh with at least a 68020 processor and System 7.
MacChess has been tested on a IIsi, Centris 610, Quadra 610, Power Mac 6100, Power Mac 7600, and a PowerBook.
Please let me know of any problems with other Macintosh models.

MEMORY AND TRANSPOSITION TABLES

MacChess requires about 2300 K, but wants more memory for ╥Transposition Tables╙.
MacChess uses transposition table sizes: 0.5 Mb, 1Mb, 2Mb, 4Mb, 8Mb, 16Mb, 32Mb, etc.
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 2300K.

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 (e.g., 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.

=============================================================================

WINDOWS

When MacChess is launched, the chess board is in the upper left corner of the screen.
There are five more windows:

Ñ PV: Principal Variation.

   This shows the best continuation MacChess has found so far.

Ñ 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 80, then MacChess thinks it stands about a Pawn better.

 - 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 mov: Number of moves considered
    The second figure shows the number of moves minus the moves leading to a checkmate.

 - move:
    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.

 - nod/sec.: The number of nodes 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.

Ñ 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't change "Player" to your name)

Ñ 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.

Ñ Opening Book:
   At program launch, this displays the version number and the size of the opening book.
   During the game, the name of the opening played is shown here.
   The lower right corner of this window displays the move number where the game leaves MacChess's opening book.

Ñ Players:
 - Play [CMD-G]
    Switches colors so MacChess has the move - also starts MacChess thinking.
    Also used in the monitor mode as MacChess must be playing from a fixed
    position.

 - Player vs MacChess:   Player (white) against MacChess (black).
 - MacChess vs Player:   MacChess (white) against Player (black).
 - Player vs Player:  Can also be used to reach a position through an opening you choose yourself.

Ñ Level: [CMD-L]

       This can also be done for the time after the time control.

    Mate in: MacChess search to a mate in ... A separate mate-finding logic is
             invoked when the level chosen is one of the "Mate in" choices.
             This finds forced mates quickly and correctly if the depth is
             correct. It doesn't always find mates faster than the regular
             search, however.
    Infinite: MacChess search till you stop it with [command] F.
       Or a forced completion is reached - e.g., forced mate.
