Disagree with all of this. The course is set up to reward good shots, punish bad shots and give average shots a chance to recover a par. It doesn't strongly favour a particular type of golfer. The list of winners includes left handers, short hitters like Zach Johnson and for a course that has 'unplayable greens', average at best putters like Garcia, Scott and Matsuyama The penalty for being above the hole, or on the wrong tier here is severe, the players know this and can play accordingly, leaving themselves a 20 ft putt for birdie, or risk it with the knowledge that there's a possibility of a big number.
The short par 5 15th is a prime example of this and a great strategic hole. If it was an easy up and down for birdie from the back, then the water at the front becomes irrelevant as the pro's would just know that going long carries no penalty. You would as well be making it a long par 4.
This course is far from unplayable, it's just very difficult and punishing if you're out of position on your approach or on the green, the number of birdies made and the historical winning scores, on only 6 occasions in the last 35 years has the winner shot less than -8, is testament to this.
