Moreover, the difference between 40/2 hrs and 40/2.5 hrs (the good old time control) is noticeable. This include the fatigue that you might have, which is generally little. After the 5 or 6 hours is when you start seing more likely chances of committing inaccuracies. Your idea that computer migh earn similar strength than a human when increasing thinking time is way wrong. Humans increase their powers with each minute extra. Computers do not do it in the same way. For instance, between two human players of similar strength one is 60/game and the other is 120/game, the first one is dead meat. The first one might hold until there is time trouble. This is nothing new. Regards, Miguel
