ΓòÉΓòÉΓòÉ 1. About UChess ΓòÉΓòÉΓòÉ
UChess is a Pentium optimized OS/2 32 bit Chess Program by Roger Uzun
(uzun@crash.cts.com). UChess is based on gnuchess 4PL73 with several
enhancements designed to strengthen its play. Both UChess and its source are
freely distributable, in accordance to the gnu license. NOTE TO WARP USERS:
Make sure your WORKPLACE SHELL PALETTE AWARENESS is set OFF in the system
settings notebook, on the screen page, if you are using a 256 color desktop.
To move your pieces simply use the mouse or type in your moves in either
shortened algabraic notation (Nf3) or long form (g1f3) followed by the enter
key. In the Time control menu, you can turn off Deep thinking to disallow the
computer to think about its next move during your turn. The machine will play a
stronger game if you allow it to think during your move.
Startup options : If the pgm seems to swap too much on your system you can use
the following arguments:
UChess mini <small tables>
UChess micro <smaller tables>
UChess Max <very large tables>
The larger the tables, the stronger the play

ΓòÉΓòÉΓòÉ 4. General Help ΓòÉΓòÉΓòÉ

shortened algabraic notation (Nf3) or long form (g1f3) followed by the enter
key. You can type "beep" followed by the enter key to toggle the beep sound.
In the Time control menu, you can turn off Deep thinking to disallow the
computer to think about its next move during your turn. The machine will play a

ΓòÉΓòÉΓòÉ 5. Index ΓòÉΓòÉΓòÉ
Use this choice to display the help index.
The help index lists the titles of the help information that is available.
ΓòÉΓòÉΓòÉ 6. Product Information ΓòÉΓòÉΓòÉ
This dialog displays information about UChess such as version number and
authors name.
ΓòÉΓòÉΓòÉ 7. Skill Levels ΓòÉΓòÉΓòÉ
Here you can choose to start the game with a material advantage.
ΓòÉΓòÉΓòÉ 8. Time Controls ΓòÉΓòÉΓòÉ
This Menu Selection allows you to set the chess clocks and various strength
parameters. You can choose to play a timed game, each side required to play <n>
moves in <m> minutes, or you can choose to have the computer search each of its
moves to a fixed ply or depth. The computer plays stronger if given more time,
and/or deeper search depths. This dialog also allows you to choose deep
thinking (on/off). Deep thinking on means that the computer will ponder its
next move while it is your turn, turning it off means the computer will remain
inactive during your move. The computer plays stronger with deep thinking on.
You can also choose to allow the computer to use its opening book or not. The
opening book allows the computer to start with some of its favorite moves,
without having to waste its time thinking about the opening portion of the
game.
ΓòÉΓòÉΓòÉ 9. Players ΓòÉΓòÉΓòÉ
This menu item allows you to choose who will play the game. You can choose to
play white, with the computer playing as black. Or you can play as black with
the computer playing as white. Or you can choose to have the computer play
against itself. In order to halt autoplay mode, simply click on the board with
the left mouse button, or press any key when the boards window is active. Note
if it is the computers turn next, it will immediately begin considering its
next move, when it gets out of autoplay mode. In addition you can choose to
have the computer simply act as a referee, and play against another human
opponent, the computer playing neither side.
ΓòÉΓòÉΓòÉ 10. Hint ΓòÉΓòÉΓòÉ
This menu item allows you to ask the computer what it believes is a reasonable
choice for your next move. The choice will appear on the upper right hand box.
ΓòÉΓòÉΓòÉ 11. Move Now ΓòÉΓòÉΓòÉ
This menu item allows you to force the computer to make his next move
immediately and cease thinking. On slower machines or while examining complex
positions, the computer may take a while to respond.
ΓòÉΓòÉΓòÉ 12. Undo Last ply ΓòÉΓòÉΓòÉ
This menu item allows you to take back the last ply, or 1/2 move. This
implicitly swaps sides, so to take back a full move, and retain your color,
choose this option twice.
ΓòÉΓòÉΓòÉ 13. Edit Board ΓòÉΓòÉΓòÉ
This menu item places you in edit mode, allowing you to place/remove any pieces
on the board. You must have 1 black and 1 white king in any setup. To exit
edit mode, press the 'x' key. To clear the board of all pieces, use the <tab>
key. To place the pieces on the board, use the mouse and the left mouse
button. To choose which piece you want, simply type in the chess letter of
that piece, lower case for White, upper case for Black. Type <space> to choose
"no piece" e.g. to remove pieces from the board. The chesspiece letters are
p,n,b,r,q,k for Pawn Knight, Bishop, Rook, Queen, King.
ΓòÉΓòÉΓòÉ 14. Calc nominal Pgm rating ΓòÉΓòÉΓòÉ
This menu item will destroy any current game in process. What it does is to
measure the time it takes for UChess to calculate the first move, as white, to
a depth of 6 ply. This gives you a rough idea of how fast your machine is, and
how strong its chess rating may be. A Pentium 90 machine takes about 2.75
seconds to calculate this move.
ΓòÉΓòÉΓòÉ 15. Test CPU Speed ΓòÉΓòÉΓòÉ
This menu item will not destroy the current game. It measures the nodes/sec
that the host computer can calculate for various aspects of the chess engine.
The number is highly dependent upon the current board configuration, how many
pieces are on the board, how many ways to check the king there are, etc etc.
ΓòÉΓòÉΓòÉ 16. Toggle Beep ΓòÉΓòÉΓòÉ
This menu item will turn on/off the beep sound when the computer completes a
move. The new beep state can be seen in the message window on the lower right
screen corner.
ΓòÉΓòÉΓòÉ 17. Toggle Verbose ΓòÉΓòÉΓòÉ
This menu item will toggle "Verbose" mode, which causes the computers thought
process to appear on the lower right hand corner of the screen, in the message
window.
ΓòÉΓòÉΓòÉ 18. Problems with UChess ΓòÉΓòÉΓòÉ
If you are having troubles with UChess's performance on your machine, it may be
because if excessive swapping. You can force UChess to use less memory on
startup by passing the following arguments into the program:
UChess micro : This forces a very small memory model (default for <8M machines)
UChess mini : This forces a small memory model (default for 8M machines)
UChess MAX : This allows UChess to use oversized tables for computers with a
lot of free RAM.
