Jerry: Of course they are going for that green. They can hit that shot comfortably and succeed 95% of the time ... that's the equivalent of you or me going for the same green from 165 yards.
But even still, most Tour pros aren't even going to look at the flag in a situation like that. They are going to aim right at the middle of the green, left-center if they are prone to missing left, or right-center if they are prone to missing right. They are going to take the water out of play just as much as possible.
One of the great golf conversations to which I've been witness was a discussion between Ed Sneed and Pete Dye about the 13th hole on the TPC at Sawgrass. Sneed was explaining how he tried to aim at the bank in the green to get the ball to feed down to the lower left pin position close to the water, and he said that the margin for error for that shot was only three feet, and no pro was that good. Pete replied that he wasn't making Ed aim at that slope ... he could aim for the pin instead, but he was being extra cautious about not pulling a shot into the water, so he had no right to complain from there.
