Listen, I can understand that for a serious chess player, the style of chess has evolved enormously during the 20th century. That doesn't make it less of a strictly codified game. Anyway, it's a matter of tastes..

One last observation. I remember that in the early nineties, a single chord from Nirvana - I was hearing them for the first time- was enough to make me say "this is not heavy metal" (I was actually pretty disgusted by that sound at the time :)). How is it that after more than twenty years (during which I haven't listened to new metal bands), 3 seconds of Meshuggah are enough for my brain to categorize them with absolute certainty as heavy metal?
