points in tournament

What to do to have 5 or 4 points in championship or tournament competition

For a lichess tournament, to get five points, you would need either two victories and a draw, or a berserk victory and a victory. Those are not the only combinations.

There are numerous ways to get four points as well. Key:
Streak win: 4 points
Berserk Win: 3 points
Streak Draw: 2 points
Win: 2 points
Draw: 1 point
Loss: 0 points

5 points straight is a streak win in berserk mode.
Translation: after 2 wins in a row you're on a streak - every immediately subsequent win is then worth double. This continues until you lose or draw a game; the streak is then finished and you must win 2 games in a row again to start a new streak.
Berserk mode must be started befor your 1st move; your clock time is halved (and any increment is cancelled), but you get an additional point for a win.
