In game three, we went to time, we played three turns and player one ended on 6 points and I ended on 4. Does player one win due to being 2 points ahead?

Yes, Player 1 is declared the winner of that game, and consequently the winner of the match.

According to Tournament Rule 408.2.b:

"If the game is incomplete at the end of the additional turns, a player is declared the winner of the game if they have a point lead of two or more. If no player has a point lead of two or more, the game is a draw."

Since Player 1 has 6 points and you have 4 points, they have exactly a two-point lead, which satisfies the requirement to be declared the winner of Game 3.

Because this was Game 3 of a Best-of-3 match:

1. Game 3 Result: Player 1 wins.
2. Match Score: Player 1 now has 2 game wins to your 1 game win.
3. Match Result: Player 1 wins the match (per Rule 408.3.a, which states the player with more game wins wins the match if the end of match procedure is completed).
