 There is one strategy that deserves a special name, because it is the identity morphism in the category whose objects are games and whose morphisms from \(G\) to \(H\) are the strategies on \(G \multimap H\). The copy-cat strategy \(\textsf{id}\) on \(G \multimap G\) is defined as the set of sequences of moves \(s\) such that the restriction of \(s\) to the left instance of \(G\) coincides with its restriction to the right instance.
