Advanced Options

Modify Mode
You can edit the actual board position by selecting Edit Modify to put in Modify Mode.You can add red or yellow pieces or delete them. The status line shows the number of red and yellow pieces, the move number, the side which is to draw the next move, and whether the position is valid: An exclamation sign means no, a checked symbol yes.
If the position is invalid and you switch back to normal Play Mode, you can't play! Only valid positions can be used as a starting position for a game.
Take back and Forward simply decrement and increment the move number, but don't change any pieces.

Usage
By pressing the left or right mouse button on an empty or yellow field, you enter Red piece Adding mode; by pressing the middle button on an empty or red field, you get in Yellow piece Adding mode. Finally by pressing the left or the right mouse button on a red piece, or the middle mouse button on an yellow piece, you enter Piece Deleting Mode. Any piece that the mouse passes over with the button pressed will be deleted.
To exit Modify Mode and re-enter Play Mode, just uncheck Modify in the Edit menu.

Using the Clipboard
The current board can be copied to the clipboard using the Copy command in the Edit menu, and then pasted back in using Paste. This way you can copy the board positions of one program to another by pressing Copy in one program and Paste in the other, but this is better done with Network Mode (see above). Another usage is to save positions into a text file (using Copy and your Editor of choice) and retrieve a position later by selecting it in the editor and pasting in .

Computer Level
The computer can play at four different levels, namely:
Easy
Normal
Hard
Challenge
The harder the setting, the longer the computer searches for a move. You can interrupt the search by pressing the S key.

Spying
Spying can be turned on and off from the Settings menu, and the Spy option. If it is your turn, you can see the computer's rating of the move you want to play in the status bar. If it's the computer's turn you can see (in status bar and highlighted pieces) the move he actually thinks is the best to play. Of course this changes along his search.

Selecting what color the computer plays
You can make the computer play Red, Yellow or both sides. Choose between these options before starting a new game. Of course it works in a game too if you want to change sides. Choose None to play against another human. This is very useful in Network Mode.
