To play a game against a calculation module it is necessary to enter the online meeting room pressing the button () on the main toolbar of the viewer, just as you do to play games online against remote opponents.
In that window, pressing the connecting button () shows a list that contains, in the first items, the connection profiles for the Meeting Rooms to play online and next the registered engines. To play against one of them, just click with the mouse on the corresponding line.
The toobar window
changes, now showing the following buttons:
In the right side we are informed about the loading process of the engine as well as the options configured for it:
The board is configured for a standard game, in which the module plays as Black and the time control is 10+5 (10 minutes, plus a five seconds increment by move.)
To begin to play, simply press the start button () and make yur first move. The module will start calculating and we can follow the progress of those analysis in the lower left side of the window:
The calculation window can be hidden by the button ()of the toolbar.
If you want to adjust the playing options, click with the mouse in the area showing the current options:
Clicking there opens up a window in which you can alter the side to move and the time control:
Furthermore, it is possible to set up the game's position by the button (). First you need to copy to the clipboard the new position in FEN format, then you press the button.
It's also possible to set up games between engines marking the option "Engine at both sides."
Even when different engines claim to be UCI compatible, they do not implement all the possibilities of this protocol, what's more, they could implement them in different ways. There are two critical points, the way in which it is necessary to communicate with the current position on the board and the capacity of the engine to calculate while the opponent is thinking to improve its power.
To deal with those different working options, the toolbar contains the buttons: () and
().
The first, () being repeatedely pressed, allows to set up to three modes of analysis so that the engine can try to calculate on his opponent's turn to move.
() Full analysis
() Simulated analysis
() Not possible to analyze
The second button () defines the way of sending the position to the module
() Position in FEN format.
() Current position of the game.
If for a certain module, you adjust one of options that it does not implement correctly, an error will occur, or the module will suggest absurd moves or simply it will not do anything at all.
When you register the calculation modules, by the standard option (), the viewer adds two more options to the list to allow you to define the two features that we have just described:
VsIA ponderar (0,1,2) default 2 (no)
VsIA modo env�o posici�n default 0
When a module is loaded, the values set for those two options are read, and the icons () and
() reflect those values. Using those buttons one can change the values temporarily. The registered
options can only be changed definitively through the option to register modules, so altering the values temporarily is a possibility that, normally, will be used when we are testing a new module and we do not know yet its full possibilities.
