 Caruana faced a Four Knights Game with 4.Be2, an opening that he has never seen before, but at the end still won the thrilling game against Andrew Greet of Scotland.The issue with the incomplete pairing was handed down from the first to the second round and 14 African teams remained unpaired, meaning that the total number of teams actually playing was 166 instead of 180 as expected, which was 10 less than at the previous Chess Olympiad.
