+		And who is X and who is O
+
+Scenario: My Turn
+	Given I have a started Tic-Tac-Toe game
+		And it is my turn
+		And the computer knows my name is Renee
+	Then the computer prints "Renee's Move:"
+		And waits for my input of "B2"
+
+Scenario: Computer's Turn
+	Given I have a started Tic-Tac-Toe game
+		And it is the computer's turn
+		And the computer is playing X
+	Then the computer randomly chooses an open position for its move 
+		And the board should have an X on it
+
+Scenario: Making Moves
+	Given I have a started Tic-Tac-Toe game
+		And it is my turn
+		And I am playing X
+	When I enter a position "A1" on the board
