Well, in that case, all board games are a stupid analogy because that describes them all... and I don't disagree with you except that great Chess players (and I'm talking the best in the world) don't tend to be idiots. Bobby Fischer may have been crazy but his IQ was said to be 160. That is Stephen Hawking level smart.
Theres a lot more to it than most think. There is game theory, "leveling", range meshing, etc. Dummies will always play on level 1 - what do I have? Most will advance to level 2 - what does my opponent have? Few get to level 3 - what does my opponent think I have (and how to react based on this perception)? Level 4 and beyond becomes a leveling game few ever reach.
