I love number 3 at Pebble -- excellent hole IMHO.
The tee shot is what makes the hole excellent, since you have to be left enough to not be on the slope to the right. If you bail out away from the trees to the right and you hit the ball solidly, yoiu will be above the green to the right and in the rough.
On the second shot, you will have a downhill wedge to a green that slopes mostly right to left, and the ball is above your feet. That is NOT an easy golf shot, since it's so easy to get the ball going left from that lie. Get it going left, and the ball won't stay on the green.
As for number 1, I like the hole. It lulls you to sleep off the tee, but the green can be tough to hit -- especially with the butterflies still fluttering around inside!
