In Section 10.2 of the Fritz5 manual, the "single-click" entry mode is described. In many chess programs the user has to click twice to move a piece: once on the piece to be moved and once on the destination square. This can cause the user to actually lose a game in blitz games, speed games, and games in which the user is in time pressure because A) the act of moving a piece in this manner on a computer screen can take longer than making the same move on a real chessboard, and B) the computer program can move much more quickly than a human player.
Single-click entry causes Fritz5 to "guess" where you want to move when you click on a piece. When a piece is selected, Fritz5 will highlight a square where it "thinks" you want the piece to go. If this is in fact the proper square, you can simply release the mouse button and Fritz will move the piece to that square. This is obviously much faster than having to click once, move the mouse cursor to the new square, and then click again.
However, some users are concerned about the "touch-move" implications of this feature. In older versions of Fritz, if you clicked on a piece and then decided to not move it, you could simply release the mouse button on the same square and then make another selection. Single-click movement doesn't allow this; if you click on a piece, you must move it.
There is a way to turn off the single-click move feature. You'll find a file called f5.ini in your FRITZ5 folder on your hard drive. Use a text editing program (such as Notepad) to open this file. In the section called [General], you'll see a line for MiniHeumas followed by some number. Change this line so that reads as follows:
and then use "save" to make the change permanent. Restart Fritz5 and you'll find that the single-click move entry feature has been turned off.
