Three Dimensional Chess

I just heard Mitt Romney use three dimensional chess as a metaphor for the fact the world has changed since the days of simply playing friends and enemies.

I think anybody who uses three dimensional chess as a metaphor should demonstrate their understanding of the rules of three dimensional chess.

When I figured out three dimensional chess confused me, I took it out of my vocabulary.

I hope this doesn't reintroduce it. I really don't feel like learning the rules.

Plus I feel like people use it to express something beyond their understanding and still try to sound like they know what they're talking about.

That's not good, especially for a presidential candidate discussing foreign policy.

Peace!
