The game below was played in a team match called TM C.L. 2016 Div. C RO: Kopaonik vs. 300 Spartans. The match was played on 109 boards and I played on board 22 for Kopaonik. For some reason I have been able to play well when I have played for Kopaonik and so it was in this match as well because I won both of my games. The final score of the match was 125 - 93 in favor of Kopaonik. The statistics below have been taken from the LiveBook.
