Variants of chess are common everywhere, I'd hazard a guess to say that people who play chess all the time are more likely to start mixing it up to add a bit of spice to the game.
Chess 960 is a good example of the backline swapping around.
Damn true. I can still remember my high school chess coaches getting mad at us for playing bughouse, saying it ruins our ordinary playing. I never believed it would, and it was quite fun, but then again, practice time is for practice time.
