Karen definitely was not playing how she normally does in any of these last three streamed matches. These are exhibitions meant to be fun and all the players have had a great time ribbing each other, going for crazy shots (mostly pocketing them, which is the scary part) and just having a good bit of fun. Alain and Karen traded breaks for each other starting later in the match--he broke for her and she broke for him. Karen's weakness, which is nothing new, is the break. If she had a big break, she'd dominate most anyone she played. That being said, after about 30 games, they started fooling around and shooting crazy shots on the 9 and when they started loosening up and playing like that both players were free wheeling and running out from everywhere. Karen Corr is one of the best kickers in pool man or woman and though we so often see her defensive game in matches on TV and in tournaments, she is an offensive beast when she plays the shots. So the 21-20 scoreline was obviously not the final match score if both players were serious about winning, but each played very well at the end.
By the way, I haven't seen the matches anywhere on YouTube or Google Videos but they are still available on the streaming website at the bottom of the page. Just click the link provided in the opening of this thread and scroll down.
