Abstract
The Strong Ramsey game is a two player game with players and , where and are -uniform hypergraphs for some . is always finite, while may be infinite. and alternately color uncolored edges in their respective color and begins. Whoever completes a monochromatic copy of in their own color first, wins the game. If no one claims a monochromatic copy of in a finite number of moves, the game is declared a draw. For a , let denote the together with the edge connecting the two vertices in the partition class of size 2. The purpose of this paper is to give a winning strategy for in the game .
