The Czech Republic put on an excellent display of chess and computer power, winning every match but one – a 2-2 tie with runner-up Germany to win the 16th Olympiad by five points.  This was the last Olympiad to be played by post. The US did not fare well in this Olympiad, drawing six of its twelve matches, losing five, and winning only one, against England. Alik Zilberberg held down first board for the US, scoring 5 ½-6 ½.  Ed Duliba finished with 4-8.    Keith Holzmueller had an outstanding +3 undefeated  result to score 7 ½-4 ½ and Jerry Weisskohl holdng down fourth board scored 3 ½-8 ½.
