Its in between. If you *can* make a move in a day in a three day limit but choose not to, its intentionally playing slow. Usually the people who use all their time are ones who have 200+ games ongoing. Its still a question of is using all of your time in the hopes that someone flakes out, gets banned, etc is actually a winning tactic.
I see two people otherwise equal in a 3 day tournament; one makes a move every day, one makes a move with hours to spare. The second will consistently perform better.
I have been seeing a trend in daily tournaments; playing slow increases your chances of advancing.
There have been enough times I have seen the one player who uses two and a half of the three day limit to make a move gains an advantage because of people flaking from the site. A person who made at least one move a day will end at least one if not both of their games against a particular opponent. The slow mover however will end up gaining more points if a particular opponent flakes two months down the road.
Should everyone intentionally play a bit slower, or should there be some sort of mitigation to detract from playing slowly being a slight advantage in daily tournaments?
