 The opponent has no further possible move. Because her repetition rank is \(\rank{1}\), she cannot challenge again the proponent’s move, as established in the   Game-playing Rule SR1i.  Notice that moves 3 to 6 follow the rule SR1i: after the repetition ranks have been chosen, each move is a challenge or a defence in reaction to a previous move. Since O cannot make any move after move 6, the proponent wins the play according to the  Winning Rule SR3.
