I believe 5 at Cal Club is actually a very good hole strategically, but the bunker pattern does not fit with what we're used to seeing for short par 4's due to the uphill nature of the hole. Allow me to explain...
The approach to the green is significantly uphill, and unlikely to be into the wind. While there is a backstop on the left side that is useful for back left hole locations, everywhere else on the green requires a controlled, high trajectory, and fairly high spin shot to hit, hold, and give the golfer a good chance at birdie.
My last time playing the course, I decided that hitting driver would be advantageous as I could take the right side bunkers out of play completely. I hit a good drive down the middle, which was not a guarantee. Not quite the preferred right side but I was in good shape and had 68 yards left to the hole.
Playing to a front left hole location I found myself staring at far more front bunker than visible flagstick. I don't mind less than full wedges or even opening the face up, but this was not exactly the position I wanted to be in. My full lob is comfortably 85-90 yards, and other full wedge distances would have put me right between the bunkers off the tee. Turns out they are protecting prime real estate. I ended up safely on the back of the green and two putted for par. I didn't feel like I missed my birdie opportunity on the hole but did play the hole in a riskier fashion than necessary. If given the option again I'd probably lay up short of the left fairway trap to leave 120-125.
To conclude - the fairway bunkering does not mesh with the greensite in a way to scream "HEY, PLAY THE HOLE THIS WAY FOR A BIRDIE" but does offer distinct risks/rewards in how the player chooses his route. If I played there often I'd imagine my strategy would change depending on what clubs were working in my bag and where the pin was located that day. That to me, is at the least a solid golf hole.
