If you won the first game and the second game is a draw, play the 3rd game. If time is called before the 3rd game finishes then you win the match.
When time is called, turn player finishes the turn. Then you look at the game score (number of wins and losses of games that have been completed), Since you won one game and your opponent didn't win a game (draw is not winning and the third game is not complete) then you win the match and the 3rd game is considered 'not completed'
If the 3rd game finishes and your opponent wins then you must start a 4th game.
When time is called, turn player finishes the turn. If the 4th game is not started then the Game score is a tie and you start the 4th game in sudden death (as descibed above). If the 4th game has started, then after the turn ends you compare Life points and that player is considered to win that game and the match.
