Why does the first person want to cut the cake first?

The first person wants to cut the cake so as to maximize his share min (x, 1 – x). The maximum value of min (x, 1 – x) for x between 0 and 1 occurs when x = 0.5, which means 1 – x is also 0.5. So the first player will cut the cake into 2 equal slices and the “I cut, you choose” method produces a fair division of the cake.
