I did a little Google search on the course. Congressional is described as having tree lined fairways with generous landing areas. It's also described as a difficult hilly course. With it's hills and rolling terrain it has the feel of a links type course. So it could be an advantage for both the big hitters and European golfers.. Ernie Els was the last golfer to win the Open on that course. And he was a pretty long hitter back in 1997 when he won. There have been several other tournaments that have played at Congressional. The Kemper Open, which had such notable winners as Craig Stadler, Fred Couples, Greg Norman and Sergio Garcia (mostly long hitters). The AT&T National was also played there. This is the one that was hosted by Tiger Woods. And the two winners in those tournaments were Anthony Kim and K.J. Choi. So you have to think that Choi will be comfortable playing there. And confident after his big Players win.
