a dominant strategy is: optimal regardless of what other players do

Can you always win a game no matter what others do?

Imagine you're playing a game of chess. You want to win no matter what your opponent does.

A dominant strategy is like choosing a chess move that guarantees you a win, no matter how your opponent plays.

Example

If you always play your queen early in chess, it's a dominant strategy because it can lead to victory regardless of your opponent's moves.

Remember this

A dominant strategy guarantees the best outcome for you, no matter what others do.
