What I observed happen was that Scott started out playing the strategy of old-school 1-pocket to play defensively and to try to keep Dennis off the shot, like he indicated in his pre-match interview.
Scott then found out that Dennis can also move pretty good and that he couldn't get to the first shot before Dennis playing like that.
After being down 5-0, Scott then played his typical power 1-pocket, and he started getting in stroke and winning.
Dennis' shotmaking started to falter later in the day, probably due to the increasing pressure as the day went on.
Overall, great match. It appears to me that if Scott plays his normal, aggresive style, he has the best chance to win.
