TBs would be tie-break systems. There are several different systems in use, and the tournament organizers will usually list more than one, so that if two teams are tied for a prize, the first TB system is used, if still tied then the second system is used, etc.
Typical TB systems: http://en.wikipedia.org/wiki/Tie-breaking_in_Swiss-system_tournaments
Ah... check down at the very bottom of the page in the link that you gave in your post:
Tie Break1: Matchpoints (2 for wins, 1 for Draws, 0 for Losses)
Tie Break2: Olympiad-Sonneborn-Berger Tie-Break without lowest result (Khanty-Mansiysk)
Tie Break3: points (game-points)
thanks a lot blueemu
Hello everyone. I was recently on a Tromso 2014 chess Olympiad website looking at the standings and I didn't understand certain parts of it. I was wondering if any of you could explain the TB1 TB2 and TB3 columns and how they're calculated. Here's a link to the website I'm referring to. http://chess-results.com/tnr140380.aspx?lan=1&art=10&flag=30&wi=821
