- DIFFERENCES PLAYER / TUTOR / ANALYZER

- In addition to the Players functionality, Tutor is also able to
- evaluate all positions, suggest moves and comment

- mentioned capacities, it can also perform four kinds of rollouts.

-
- STARTING A GAME OR MATCH
- 'File->New->Single game' or
- 'File->New->Match'
- If you want JellyFish to log the match or game in a .mat or .gam file,
- check 'Settings->Prompt For Log File' before starting the game/match. When
- you start the program, it automatically starts a new game or match.
-
- ROLLING THE DICE
- Click on the righthand side of the board. If you have
- 'Settings->Manual Dice' checked, it will prompt you for the dice roll,
- otherwise it's generated automatically. By choosing 'Settings->seed'
- you can set the input to the dice generator. This input consists
- of two numbers: seed and counter. By experimenting with this you
- can verify that it doesn't cheat with the dice, and that the roll
- is completely independent of level, position and other factors.
- Check 'View->Seed' to display the seed on the status bar.
-
- MOVING CHECKERS
- Click on the checkers you want to move. The dice are sorted with the
- higher first, and the dice are played in that order. If you want to play
- the dice in the opposite order, click the dice with the right hand
- mouse button.
- There is a shortcut that often works:
- If you click with the righthand mouse button on a point, the
- program looks for a play that maximizes the number of checkers there.
- After moving the checkers, you finish the play by clicking the dice.
- Until you have done this, you can take back the move by pressing the
- button with a single leftpointing arrow.
-
- DOUBLING
- Click the image of the cube. When JellyFish doubles, you get a dialog
- box where you can choose your response.
-
- FINISH GAME
- Clicking the 'running man button' on the tool bar makes JF
- finish the game on level 5.
-
- TAKE BACK
- You can rewind the game by pressing the double leftpointing arrow.
-
- EDITING POSITIONS
- You can change the position by clicking the pencil-button. You then
- remove checkers with the righthand button, and insert them with the
- lefthand button. You can also move the cube level and position by
- clicking on or beside the cube. When you're done, you press the
- pencil-button again to finish editing.
-
- SAVING/LOADING of positions
- 'File->Save'
- 'File->Save As...'
- 'File->Open'
-
- LEVELS OF PLAY
- You set the level by 'Level->...'. On the highest level (7), it prompts
- you for a time factor, which determines the limit to how long it may
- 'think' while searcing for the best move.
-
- DEMO MODE
- In demo mode the program plays a given position over and over on the
- level associated with the position. To stop it, press space bar on your
- keyboard.
-
- REPLAYING A GAME OR MATCH
- 'File->Open...' Choose Files of type .gam or .mat. Step through the chosen
- game with the double rightpointing and leftpointing arrows.
-
- CAUTION
- 'Setting->Caution'
- If you're backing JellyFish against a proffesional player in moneygames,
- you should have this switch toggled on. It will make the program stop
- doubling when the cube reaches 32. Also if the opponent doubles, and
- JellyFish thinks it has the advantage, the program will stop redoubling
- until contact is broken.
-
- There does exist positions where JellyFish thinks it's the favourite,
- when the opposite is true. These are extreme positions, and they are not
- important for normal games. Without caution set the human expert can
- seek these positions, letting lots of checkers being hit and forming a
- massive backgame. Most of the time this will fail, and he will just have
- lost 4 points from a doubled gammon. When it does succeed, however, he
- can jack the cube up to 512 paying for all the losses. This was a big
- problem with the 2.0 version, but this 3.0 version is far better at
- evaluating extreme positions. Therefore the caution setting may not be
- needed, but it's nice to have a safety net when playing for real money.
