Basic do's:
1. Shoot balls away from his pocket.
2. Shoot them so they go towards your pocket.
3. Put the cueball where he can't shoot them away from your pocket.
Basic don'ts:
1. Don't ever lose patience.
2. Don't shoot shots that can cause you to lose but can't help you win.
3. Don't ever give up in any game against anyone.
Here's a helpful tip from a current WWYD thread but is applicable to many situations. Many times when you are faced with a situation such as this (you have a 4-1 lead) you simply eliminate the balls you won't shoot and then the shot becomes more obvious.
In this example you would not shoot the 5, 10,11,4,1,14,15,13, or 6. That leaves the 12.
Many times this "elimination" method will help you see the "right" shot.
