I have a zero-sum game described by $$ A=\begin{pmatrix} 1 & 8\\ 4 & 2\\ 3 & 5 \end{pmatrix} $$
where the player 1 selects the row and he wants to maximize the utility and the player 2 selects the column and he wants to minimize the utility. In the solutions the professor starts by deleting the first row because he says that it is never selected by player 1. Can someone tell me why I can delete the first row?
