One of my favorite hobbies is treasure hunting for beautifully instructive chess games during the annual Chess Olympiads. With more than 180 countries each sending their best male and female teams to compete in one event, the Chess Olympiads is a veritable mother load of chess gems. For hunting these chess treasures, I follow along at:
