My question is if increasing the size of a chess program can reduce its speed.

I assume for the discussion that
99% of the program is almost never done.

Suppose that a programmer writes long code for a lot of special cases about
specific endgames.

Assume that detecting that you are not in one of the special cases is cheap.

Can writing the long code reduce the speed of the program significantly even in
case that the program almost never get the special cases in the search?
