Do you even realize that "modern chess" is a EXPTIME-complete problem?
Notice that although we don't know if NP is equal to P or not, we do know that EXPTIME-complete problems are not in P; it has been proven that these problems cannot be solved in polynomial time, by the time hierarchy theorem.
i mean what's to say the traditional/original game of chess that originated in India before European intervention was inferior..what if it was a more complex, in-depth game than "modern chess"
