Adjusting the program's playing strength

Click Game and then Options. Choose the Playing tab. To make the program play weaker perhaps the easiest way is to increase the maximum evaluation error with the slider. To make the program play at its strongest have the quiescence search checkbox checked, use hashTable and reduce the maximum random evaluation error with the slider to zero. A small random evaluation error will make the program play more varied but still close to its best. An increase of search depth in plies or an increase in the search time in seconds will of course make the program make stronger moves. Quiescence search in this program is when the program looks at most piece exchanges until there is no more pieces to be taken by either side before evaluating a position.
