We investigate the adaptation of cooperating strategies in an iterated Prisoner's Dilemma (IPD) game. The deterministic IPD describes the interaction of N agents spatially distributed on a lattice, which are assumed to only interact with their four neighbors, hence, local configurations are of great importance. Particular interest is in the spatial-temporal distributions of agents playing different strategies, and their dependence on the number of consecutive encounters n_g during each generation. We show that above a critical n_g, there is no coexistence between agents playing different strategies, while below the critical n_g coexistence is found.
