Why do you make the program slower by giving it so many option.

You should let it search deeper by giving it less options(usually I prefer only
1 option(2 may be also acceptable but I see no reason to give it 43 options
because it waste too much time on analyzing stupid blunders only to get an exact
score for them that is not interesting).
