From Wikipedia
Each match of the quarterfinals consisted of two “slow” rapid games (45 minutes for 40 moves plus 15 minutes for the rest, without increment), two “fast” rapid games (15 minutes plus 2 seconds increment) and 2 blitz games (3 minutes plus 2 seconds increment). The games were weighted differently: 3 points for each slow rapid game, 2 points for each fast rapid game and 1 point for each blitz game.
I believe this applies to the semi-finals and finals too. For the 9 matches of the quarter-finals and the 4 matches of the semi-finals and finals (4 includes the 3rd place match), for anyone that lost the 45min (slow rapid? Classical?) portion of their match, did they catch up and win the overall match?
