Imperfect Defense on Two Routes

A defender chooses whether to patrol Route $L$ or Route $R$. An attacker chooses which route to use. The defender's payoff matrix is \[ \begin{pmatrix} -0.2 & -2.0 \\ -1.0 & -0.3 \end{pmatrix}, \] where rows are the defender's choices and columns are the attacker's choices. Find the equilibrium mixes and the value to the defender.
