Imagine you are Player 1 in a two-player strategic interaction, and the potential outcomes are shown in a standard payoff table where your potential payoffs are listed. If you know for certain that Player 2 will choose their 'Strategy X', describe the precise method you would use to identify your own best response from the table. Your explanation should focus only on the process of finding your single best move in this specific situation.

Finding Best Responses
Dominant Strategy
Two competing firms, Firm A and Firm B, must simultaneously decide whether to 'Launch a new product' or 'Maintain the current product line'. The resulting profits for each firm depend on the actions of both, as shown in the following payoff structure, where the first number in the parentheses is Firm A's profit and the second is Firm B's profit:
- If both firms Launch: ($50 million, $50 million)
- If Firm A Launches and Firm B Maintains: ($120 million, $30 million)
- If Firm A Maintains and Firm B Launches: ($40 million, $100 million)
- If both firms Maintain: ($80 million, $80 million)
Given this information, if you know that Firm B has decided to 'Launch a new product', what is the best response for Firm A to maximize its own profit?

Ben: Clean Ben: Relax Alex: Clean (8, 8) (3, 10) Alex: Relax (10, 3) (0, 0) Statement: If Ben decides to 'Clean', Alex's best response is also to 'Clean'.
