Chess Games
Math brain teasers require computations to solve.

 would have been nice to see how that was derived. i took your first answer as a given, figured the moves were exponential, and raised it to the (10/4) power. could you please show how you came up with that answer? or is it something from a chess book?

 the "problem" that makes this so much more than mathematical, aka you can't just do (10/4) power is that it is not constant exponential growth. Think of the first move  any of 8 pawns 2 different ways, or 2 knights different places, so 20 for each player, or 400 after just 1 move by each. Then, where it gets increasingly confusing is the ability to move either 7 pawns 2 ways and one pawn 1 way, possibly 2 knights two ways and then the rook, or the bishop to a multitude of spots, or the queen or king even. this opening of possibilities raises this problem to a much tougher degree than originally expected, but to be able to figure all that out is surely mathematically sound and "simple" but intense. wish there was a more simple explanation (maybe that link would help, havent checked it yet).

 Definitely trivia as the answer was computed through trialanderror by a computer rather than calculated mathematically.
