A. Forget the steroids. Q. A car races a shark along a seaside road. The shark loses much of this advantage in having to bend its body to swim, says University of British Columbia zoologist John M. Gosline.
Water density is almost a thousand times greater than air, posing enormous drag.
This is an unfair competition, and so is shark vs. car. A second consideration is power output. So on both counts the car wins big. A. Careful here. There are actually few sequences of possible moves in a game, since by arguments of symmetry, all corner openings are essentially the same, as are all mid-side marks.
