I could understand the current obsession with trying to force top players to play on at all costs if short draws was a problem. In the 1980s many players could blitz out the opening and then agree to a draw when that was a result both were happy with. This was fairly common at the highest level, for example Spassky won Linares 1983 after drawing games in 13, 17, 17, 18 and 18 moves, and had another couple of draws in 25 moves. This in a ten round tournament. Karpov drew in 12 moves against Miles in the same event.
Today you rarely see this lack of fighting spirit at the highest level. When Carlsen won the Tal Memorial he had one draw in less than 30 moves, and that was because Kramnik preferred to go for a repetition in a better position. Seven of Carlsen's nine games were at least 40 moves long.
When Aronian won Wijk he played one draw shorter than 28 moves, when securing the victory in the last round against a Radjabov that preferred to go for a repetition in the opening instead of trying to win the tournament. Not strange that Aronian had nothing against that given the situation. Carlsen in second place had one draw in less than 34 moves, and this in a tournament of 13 rounds.
So yet another futile attempt to artificially remove draws from chess tournaments fails in Dortmund. The pre tournament publicity boasted of a cast iron 'No Draw Offers' rule which on closer inspection doesn't quite mean what it says. Although the players are not allowed to make draw offers they can ask the Arbiter to rule a position as drawn if he thinks there is no real possibility of a win for either side.
Given that most arbiters are likely to be old school players who can remember when adjournments were commonplace it stands to reason that they aren't going to force players to play on in unclear positions if both of them are happy with a draw.
Get rid of the stupid 'Sofia' rules as well and stop artificially trying to force professional players to keep going until somebody makes a mistake - draws are an integral part of top class chess and have been for a century at least, get over it..
