Not all chess analogies work well

I'm not really sure what the connection to chess is in this one:

...here in Ontario, buying gas is like a game of chess. At-the-pump prices go up and down like yo-yos, with ten cent per liter (think thirty cents per gallon) daily swings a common occurrence. So when gas is running about eighty-one cents per liter (USD$2.60/gal.), and you see it drop to seventy-four cents, you pull in and fill up. It doesn't matter if the tank is full, and it's all you can do to squeeze three bucks worth in.

Maybe they play chess differently in Canada?
