1. General Questions

1.1. Where can I find new versions of TI-Chess?

The preferred way to download new versions is from the file archives from TICALC.ORG. At this site we can see the file download counter raising and this makes us happy ;-)
The easiest way is to check Thomas Nussbaumer's author info page to see if there already exists a new version. The author's info page can be found at: http://www.ticalc.org/archives/files/fileinfo/116/11606.html
There you can find also other "brain breakers" like TI-Con45.
To find news and/or rumors about TI-Chess Team Software visit the TI-Chess Team HQ page at: http://tict.ticalc.org.


1.2. How can I contact TiCT (the TI-Chess Team)?

The preferred way is our Messageboard at http://pub26.ezboard.com/btichessteamhq or you can contact me by mail at: thomas.nussbaumer@gmx.net


1.3. How do I report a bug?

First of all, please read carefully this FAQ and the readme.txt file! Maybe your problem is already mentioned there. If not, please check if there is already a new version of TI-Chess available. See section 1.1. for details where to get new versions. If none of these suggestions helps post a bug report on our Messageboard at http://pub26.ezboard.com/btichessteamhq, which should contain the following informations (just copy and paste this block !!):

Calculator Type (TI89/TI92):
Hardware Version (HW1/HW2):
Installed AMS Version (1.xx/2.03/2.04/2.05):
Installed Kernel (if any):
Version of TI-Chess:
State of Ti-Chess (normal/archived/locked):

[--- Optional infos (must not be filled) ---]
Is the Problem re-producable:
Can it be re-produced with VTI:

If the problem is related to the chess engine itself (how the program plays chess), please save a position where the problem shows up and attach this ticsave file to the mail. Additionally attach the ticcfg file. Thanx.
By providing all this information the "problem solving process" will be much faster.


2. Game Related Questions

2.1. Why does the calculator always plays the same combinations?

TI-Chess like other chess programs calculates the best answers on your moves. Under normal conditions it will just find one best move. So it plays always the same style.
UPDATE: Since TI-Chess v3.80 BETA TI-Chess supports opening books. This helps alot "randomizing" the moves in the opening phase. If there are more than one continuation move for the actual position stored in the opening book TI-Chess will choose randomly which one it will play.


2.2. The program states "Invalid move" on a valid move. What's going on?

There are many possible reasons for this:

  1. Check if your king is in a check condition first. If this is true you have to move your king first out of the check or protect him with another figure before you can make any other move
  2. Additionally check if your king will come into a check condition when you will move the desired figure. You cannot move a figure if this would make your king "capture-able" for the opponent.
  3. Next check if one side is already mate. The program doesn't always display a hint on a mate situation. For example: If you use the back" and "forward again" keys the infoboards get cleared. You won't see the hint about the mate situation anymore.
  4. At last check if the figure you want to draw is really marked with a black rectangle. This happens more than once to me (trying to move a figure which I haven't really selected) ;-)

2.3. The program captures a pawn after a double step in a really strange way ...

You have just experienced the occurrence of the "En Passant" rule. This rule is the least used move in Chess and a little bit obscure. It can only occur when a player exercises his option to move his pawn two squares on its initial movement. When this happens, the opposing player has the option to take the moved pawn "en passant" as if it had only moved one square. This option, though, only stays open for one move. The en passant move was developed after pawns were allowed to move more than one square on their initial move. This was done to make sure they retained some of the restrictions imposed by slow movement, while at the same time speeding up the game. Check the links on the tutorial section to learn more on this topic.


2.4. What are the chess clocks for?

The chess clocks are introduced in TI-Chess 3.00 to give you a hint how long you thought about your moves and how long the calculator took up. Yet there are no functions build-in to restrict the time for each side, but this is planned for future releases.


2.5. What are Nodes (displayed on the infoboard)?

Nodes is the chess programming term for evaluated positions. If on the infoboard "Nodes: 12344" is displayed, the program has evaluated 12344 possible positions.


2.6. What is the best/last display on the infoboard good for?

During a calculator move the program hints you its "best move till now" by displaying "best:XYZ". Otherwise the infoboard will show the last move of each side with "last:XYZ".


2.7. How can I force the program to start a game with the white pieces?

  1. Start by selecting "New Game" from the menu
  2. Use the "Change Side" key before making any move. Now the calculator starts with the white pieces.
  3. If you prefer to see the board with "white on top" just use the "Rotate Board" key

A keylist for your calculator can be found in the readme.txt file.


2.8. What is a ply/what are plies?

Ply is the chess programming term for a complete move. A move consists of two "half-moves". Yours and the oppent's "half-move". So if a chess puzzle states a "Mate in 2 plies" this means that you make a move, then the opponent and afterwards you again. The opponent should now be mate if you made your moves well-planned ;-)
