direct confrontation tiebreaker

Hi.

I need find a solution to separete equals points each Player, but i need follow a "rule".

I have Two sheets (Find_Dup, Bolls_Table).
Firsth, I need find duplicate values in sheet(Find_Dup), coparing values in column B.
Secondth, I need check in sheet(Bolls_Table), who wins who, check if has same ID_Game (column C), and value in column D.
then go back to sheet(Find_Dup), write in column C a code that I can use to sort data after.

See my file, i try show result manualy on sheet(Find_Dup) in column C.

Exemple:
This players have same points >>sheet(Find_Dup)
Names-Result
Darci Gaucho-26
Marcos Rodrigo-26
---------------------------------------------
But when their play against each othe, who win?
>>sheet(Bolls_Table)
Round-Players-ID_Game-Result
Round 3-Marcos Rodrigo-2017071518-1
Round 3-Darci Gaucho-2017071518-2
Look for same ID_Game(2017071518), then Darci won, becouse 2>1
