1. Use duality and get a strategy of (3/4, 1/4) for the column player. Both ways give a value of 7/2 for their respective LP, so must be optimal.

2. It is always optimal for the row player to choose the bottom row (since in each corresponding column, the value of the bottom row is larger). The column player knows this, so she will always choose the first column. Thus, the maxmin value is 4.
