How to unlock the Dig Deep achievement in Tiger Woods PGA TOUR 13 - Definitive Guide
In game settings change the caddy to auto. Then play now on any course with Tiger as your golfer. Before starting you can go into the options to select the holes of your chosen course that have bunkers near the green or just play through he 18 (I did this while doing the 18 holes from the red tee achievement)
Once your on the course get the ball in a bunker near the green. Hit Y to have your caddy line up the shot then press up on the left stick to see where the ball will land and decide if you'll need to add spin to get it closer to the hole. Then take the best shot you can, adding any needed spin
Hope this helps
Another achievement that will probably pop as you progress through career mode. To do it quickly select the Amateur settings and a Play now course. Any course will do and i recommend just playing the par 3's in custom mode. Simply land you tee shot in the bunker. Then use the caddy recommendation to line up your chip and ensure that the target line ends at either the cup or right next to it. Simply swing the recommended power and you should land within a yard easily. This can also be achieved in any Tiger Legacy objective or online play as well.
Another trophy you can pretty much forget about, as you will more than likely get it without trying. But if in a hurry, start aiming for greenside bunkers. Remember that all chips and pitches from inside 50 yards or so will over shoot their target marker by default. So always aim a little bit short of where you think.
