Don't Cross That Line!
In an effort to generate more power and length in the swing, many golfers lift their right elbow at the completion of the backswing. However, this "flying" right elbow often tilts the shaft of the golf club "across the line" or plane. If you cross the plane, it is very difficult to get the club back on the proper plane prior to impact and you will suffer inconsistent contact and loss of power. In other words, you are creating a zig-zag in your swing that requires too much timing. If you "zig" off plane at the top, you will have to counter that move by doing a "zag" on the way down. Good luck timing that!
To improve your position at the top of the backswing, place a Nerf football or sponge between your elbows. When you swing to the top, your elbows should remain close together and the sponge should remain without falling.
Notice in photo 1 that my club is hidden behind hands and has not crossed the line.

In photo 2, the football is falling and the club has crossed the line at the top.

In addition to the Laser/Flashlight Drill, this is a great way to practice and improve your swing plane.
