The page is the online manual for HIARCS Palm Chess Pro 13.1. The manual is

the game. Hiarcs will also resign for itself in hopeless positions. Hiarcs
does not resign on instant levels (except Challenger) or at Set Elo levels
below 1400 Elo because players at these weaker levels should practice
delivering checkmate. On the stronger abilities Hiarcs will resign if it
considers the position hopeless. When Hiarcs resigns the game result is set,
however, if you wish to play on you may and Hiarcs will not offer its
resignation again in that game enabling you to practice finishing the opponent
off to checkmate.

Playing Levels screen
The Playing Levels screen allows you to set many aspects of the playing
level. Click any of the following to read more.
There are many levels to select from as follows:
- Instant Sparring - these are beginner sparring levels which are
instant, they are in Elo steps of 50 Elo from 750 Elo to 1200 Elo
- Casual Move Time Presets - this is a settable time for which Hiarcs
will aim to think, sometimes more, sometimes less
- Game In Preset - this is a set time for which each side must play
all their moves
- Move Bonus Preset - this is a set of time controls including time
bonuses for each move (ie. fischer increments)

You can view the presets in their categories below.
Beginner Instant Sparring
Casual Move Time Presets
Game In Preset
Time Control Preset
Move Entry Bonus
For any level you can set the Move Entry Bonus - this is a bonus time between
1 and 5 seconds which is allowed for you to enter a move. Your clock cannot gain
time if you use less than the bonus time for a move, but when using time to
enter you move your clock will gain up to the bonus time. This gives you a
little extra time to enter your moves and avoid losing on time.
Handicap Limit HIARCS chess strength
Class of Elo
To handicap/limit HIARCS to a specific Elo strength you should check the
Handicap/Limit checkbox. Once selected, you can then either select the exact Elo
you entering it into the numeric Actual Set Elo field or use the arrow buttons
to decrement/increment the Elo count. The alternative is to use the Class
selector to choose an Elo range. If you select a range at or above the maximum
strength on your device Hiarcs will automatically switch off the handicap.
The minimum Elo is set to 750 Elo for all Palm devices. The maximum Elo is
computed based on the performance of your device and hence this figure varies
widely between devices depending on the performance of the underlying hardware,
especially the CPU.
Time Control screen
The time control screen enables you to set the number of moves to play in a
time period and an increment for each of up to 3 time controls. Additionally you
can define the number of times each time control is used. A zero for the moves
indicates that ALL moves should be played. A star will appear in the "x times"
field where the time control should repeat, the last time control
Play Role options
The Hiarcs Role message box gives you the choice to set what Hiarcs' role in
the current game should be. Choose Analyse to get Hiarcs to begin analysing the
current position while it awaits you moves which it will continuously analyse.
To have Hiarcs just watch as you enter move select/tap the Watch button. To
simply play a game against Hiarcs select/tap Play Game.
Engine Room screen
The Engine Room screen allows you to configure the HIARCS chess engine in
detail. Select/tap the OK button to apply any changes to the Engine Room
settings. Select/tap the Optimise button to set the parameters to their optimum
settings. To cancel any changes tap the Cancel button.
The following options can be checked on or off:
|Learn Positions - when on, Hiarcs will try to learn from the positions it
plays or analyses to improve its future performance. Default is ON.|
|Smart Search - when on, Hiarcs will use a smart search approach which is
normally more effective. Default is ON.|
|Perm. Brain - when on, Hiarcs will use the time when it is your move to
continue thinking about its future moves in response to the move it expects
you to make next. Please be aware permanent brain can drain the battery more
because Hiarcs spends more time thinking and therefore you will be warned
about this if Perm Brain is ON when you click OK. For tournament games or for
optimum performance this setting should be ON.|
|Avoid Draws - when on, Hiarcs will try to avoid draws where it can without
risky defeat too much. Default is OFF.|
|Combinations - when on, Hiarcs explores tactical combinations in more
depth which should improve tactical strength but at the cost of some
positional strength. Default is OFF.|
|Deep Search - when on, Hiarcs performs a deeper search analysis which
normally proves to be very effective. Default is ON.|
The following options can be selected from the pop up selectors:
You can set Hiarcs to Show its Thinking in the following ways:
|Off - no thinking shown|
|First Move - shows just the next move Hiarcs is considering|
|Full Variation - shows the full variation Hiarcs is currently intending|
|Full Analysis - show the full variation but also during thinking on the
You can also set the Hash Table size for the engine. The available hash
tables depend on the available dynamic ram on your device.
Three playing styles are available, Normal, Aggressive and Solid with Normal
being the default.
You can configure the depth to which threats are computed ahead with the
Threat Depth setting. The default of 5 is the best since it spots impeding
threats better for both sides.
The search can be configured for its degree of selectivity. The most
effective setting is the Extremely Selective option which allows Hiarcs to reach
greater search depths at little risk.
You can download many opening books from
www.hiarcs.com including the small, medium, large and full books. The book
choice can be selected between a number of settings:
|Off - Book is not consulted.|
|Wild - Hiarcs will try to play a very wide variety of book moves often
leading to wild risky lines of play|
|Surprise - Hiarcs will play surprising lines which are generally a
stronger choice than the Wild book moves|
|Playable - Hiarcs will select from a set of generally playable lines|
|Tournament - Hiarcs will select from the best moves available. This is the
book setting that should be used for all important games or tournaments since
the level of play achieved is higher.|
When analysing or trying out different game continuations you can use the
unique game branch feature of Hiarcs Chess Pro.
Let us look at an example to see how this new feature works.
Here we are analysing game variations. We reach this position at the start of
the modern Sicilian defence. Here we start analysing the Najdorf continutation
5...a6 and follow a line reaching this position:
Now I decide to go back to the first position diagram and try a Sicilian
Dragon with 5...g6.
At this point Hiarcs detects a possible game branch and asks if how you wish
to treat the current game. Your can choose one of the following options:
|Overwrite - this means the existing game continuation (Sicilian Najdorf)
will be overwritten with the new move and subsequent moves|
|Branch - this means Hiarcs will save the current game continuation to the
Hiarcs Game Database and will start a new continuation with the move 5...g6|
|Cancel - this means Hiarcs will cancel the move 5...g6 and return to the
I choose to the Branch option and I then continue to enter moves in this new
game variation reaching the following position:
Now I wish to go back to the previous game branch to re-look at it so I
select the Prev Branch menu option:
Hiarcs now saves the current branch (which was the Sicilian Dragon) and
returns to the previous game branch which was the Sicilian Najdorf variation.
You can press the forward button to move through the Sicilian Najdorf line.
At anytime you can go back to the Sicilian Dragon line by selecting the Next
Branch menu item.
In the event no more branches are found in the direction requested you will
see the following error:
Hiarcs will store how the game branches are related in the event header using
a special symbol. As a result if you later load a game with game branches you
can navigate forward and/or backwards through the game branches using the Next
Branch and Prev Branch menu items.
In addition when deleting a game from the Hiarcs Game Database, if Hiarcs
notices it is part of a set of related game branches you will be offer the
option of deleting all the game branches at the same time. In this way to can
manage the Hiarcs Games Database better.
