Version 3.1

Release Date

2009-03-03

What's new

The main purpose of version 3.1 was the addition of i-Books, but as usual a number of other smaller features were added, mostly based on user requests. The change log can be found below, but we start by looking at the new features.

Description of new features

i-Books

This is another major feature that current owners of Aquarium get for free. i-Books allow users to enjoy interactive chess books in Aquarium. i-Books allow much more flexibility than traditional game annotations. As the name indicates they can also be used to write books that are structured in a similar way as traditional chess books. The image below shows a typical, short i-Book consisting of some text, analysis, images and diagrams. It was created by converting the original tenth round report from the recent Corus tournament to an i-Book.

The report itself runs down the right-hand side of the image. The difference from the original is that the moves mentioned in the report are clickable in the i-Book. When you click a move, the corresponding position is displayed on the chessboard in the upper left corner so you can easily follow the variations discussed in the report. The game notation – with the analysis – is displayed below the board. Other information, such as a table of contents and a tree configuration can also be displayed in an i-Book if the author chooses.

For further information see the article Interactive Chess Books in Rybka Aquarium(external link) on ChessCafe.

Besides viewing i-Books in Aquarium they can also be published on the web or exported to a word processor, such as MS-Word.

Game Analysis in the Sandbox

Now all of Aquarium's analysis methods are available in the Sandbox, including Game Analysis. This enhancement has been requested by many users.

Improved graphic annotations

The usability of graphic annotations is greatly enhanced in Aquarium 3.1.0. The new graphic annotation palette stays open while you are annotating a game, so adding graphic annotations to a game is much faster than before. Just pick the shape and color from the palette and apply it as many times as you like to any position in the game.

The graphic annotation palette is (of course) located on the Comments tab. Click the Color Marks button to open the palette.

Show threats when starting infinite analysis

A new option allow you to display the opponent's main threat graphically on the chessboard when starting infinite analysis. This unique, little feature will can be quite helpful, even for strong players, although it will probably be most appreciated by weaker players.

You can activate this feature in the analysis options as shown in the image below.

Image

Select 'Limited depth' and set the depth to the desired value. Normally you would choose some low depth value (depending on the speed of your computer) as you don't want this step to take too much time before the actual analysis of the position starts. The threat found by the analysis is displayed on the chessboard with a curved red arrow.

The example below shows that White's main threat is not to capture the bishop on f5, but rather the deadly g4-g5+, which would be followed by a knight fork on c6 or f7 depending on where the black king moves.

Smart input - even smarter!

User 'Bunt' on the Aquarium forum(external link) thought that the 'Smart input' option wasn't smart enough and asked for enhancements. The developers have now implemented his suggestions. If you have selected the 'Smart input' option try to click on a piece (that can move) or a square that more than one piece can move to. While holding down the left mouse button press the right button. This allows you to cycle through the possible destination squares for a piece or which piece should move to the selected square.

Image

Here the user has clicked on the d7-square and is holding down the left mouse button. Both the knight on b6 and e5 can move to that square. The knight on b6 is currently highlighted, so it will be moved to d7 if the mouse button is released now. The other knight can be selected instead by pressing the right mouse button.

Manually adjust play percentages

Play percentages in Aquarium opening books can now be manually adjusted. Right-click on a cell in the 'Play %' column and select 'Edit percents...'.

Image

You can also use the keyboard shortcut shown at the end of the 'Edit percents...' line in the menu. The "Edit Percents" dialog box is displayed.

Image

In this case I am going to change the percentage from 23 to 15. When I click OK the book will be modified.

If you want to restore the automatically calculated percentage, open the "Edit Percents" dialog box again, remove the check mark in front of "Set playing probability and click OK.

Tree window: Select configuration

Now it is even easier to switch between different tree configurations in Aquarium. There is a new button, a downward pointing triangle in the title bar of the tree window (see the button circled in the image below). Clicking that button displays an alphabetically ordered list of all available tree configurations. Select the one you want from the list.

Image

Only show main tree moves in a tree configuration

Normally a tree configuration will populate the 'Move' column in the tree window with all the moves present in any of the trees that comprise the configuration. Now you have the option to show only the moves from the main tree.

While viewing a game, select the Tree tab and click Options. The 'Tree Configurations' dialog box will be displayed. Click the Advanced button to see the additional options.

Image

Enable the new option by selecting 'Show main tree moves only'.

Auto232 support

Auto232 is an old protocol, designed for allowing engines on different computers play against each other. Aquarium supports Auto232, although it is not recommended unless other methods are not available. It is a bit tricky to connect two GUIs via Auto232 and you need to perform the required steps in the order given below. Auto232 support will be improved in upcoming versions and we encourage feedback from Aquarium users.

As an example of how to use this feature, the steps required to set up a match between Rybka running in Aquarium and Fritz are described below.

1. Aquarium. Create a new engine as shown in the image below. It will be used to connect to Fritz.

Image

Type: Auto232 Slave

Engine path: \\. (\\ followed by a dot)

Name: Any name you want. In this example I call it 'Fritz Remote'.

2. Aquarium. Select the engine you want to play in Aquarium and set the engine priority.

Image

In this case I have selected Rybka 3 w32 and I change its priority to 'Normal' (Essential for playing on a single computer, but also advisable for network play). You can of course choose any other installed engine.

3. Aquarium. Create an engine match, between Rybka 3 w32 and Fritz.

Image

White: Fritz Remote
Black: Rybka 3 w32
Switch sides: yes
Time control: Set the correct time control. You must make sure that you chose the same time control in Aquarium and Fritz.

Image

The critical parameters are highlighted in the screenshot, but of course you may also want to set other parameters. Note that the opening book and hash size settings have no effect on Fritz Remote. All its parameters must be set in the Fritz GUI.

When you click OK, the match will be started on the Aquarium side, but the clocks won't start running until we have finished the setup on the Fritz side, so we can take our time for that.

4. Fritz. After setting the Fritz parameters as you like, you should specify the same time controls as you did in Aquarium. In our example we chose 3 minutes/game plus 2 second increment, so you should do the same here. After that, go to File -> New -> Two Computer Match.

Image

Select Auto232 1.0

Select Server name and then enter the server name where Aquarium is running (skip the initial \\)). Example: 'zruty'. If you are running Aquarium and Fritz on the same computer a '.' (dot) also works.

Click OK and Fritz should connect to Aquarium after that.

5. Fritz. There's a next dialog. Input engine names, click OK.

Image

Voila! The games are now started.

To end the match, you can stop the GUIs in any order: Stop Game in Aquarium, red cross in Fritz.

Checked with Fritz version 9 and 10.
