phred952: It's like the first Par 5 on Bethpage Black. It tempts you to shoot over the bunkers to the green. But you either come up short and get to play in the sand, or you're long and can't hold the green, running off the other side. Both reduce your chances of a birdie by a lot.
I hate to disagree with you on this, but I'll do it anyway ;-)
#4 is a much easier birdie, if you shoot for the green. Played correctly (full bs, adding about 20y of power to stated distance in side wind, adjusted for other wind), you should end up a yard or 2 off the green. From there you have an easy pitch to a flat surface (unlike when playing from the right and short), which is in fact a decent eagle chance. There are a few spots (long and a bit to the right), where all you need to do is ding the pitch, it's totally straight, all you need is the correct power and a ding. Although, I haven't had more than a couple of dings (or even close to 1) per round, since my PC broke down in the beginning of October :-(
The only thing you need to worry about, when going for the green, is not landing on the green before the hole. There's a nasty slope, which can make your ball shoot far away. But the bunker in front of the green is an easy out, the 10-15% lie is easy, just play a full bs flop with the correct power and you should end up not more than 5-6 feet from the hole.
Of course, the above only goes, if both your clubs and balls have a decent amount of spin ;-)
