Well I need chi20 to win his round against Trofo but currently Trofo leading with 1 point with 5 more different answers.
They have 4 more different answers, not 5. You counted wrong.
I just checked the first division table and I see to finish the league at the second place, you need to win your own match and Trofo not to win.
No difference whether Trofo loses or draws. Therefore, a draw in Trofo vs chi20 match will be good for you too.
