Last week I went to our practise bunker and hit 70 balls out of it. I thought at last I have cracked it! The sand was firm and wet. I went to play yesterday. The first bunker I got in I naturally thought, this is going to be easy. However, it took me 4 shots to get out of it. The only difference was that it was soft powdery sand. I hit the shot hard but the ball only move to the lip of the bunker and rolled back in. What am I doing wrong here do you think? Am I taking too much sand? If so, how do I fix this please?
