After the most recent top Starcraft tournament (gsl code S), they asked the loser why he lost. He said, "I worked hard to prepare for this tournament, but my opponent prepared better." What kind of things did he prepare? It wasn't reflexes, it was strategy. What kind of strategies was he preparing? He watched his opponent's past games, and came up with some build orders of course, but in this case, the primary strategy he came up with was an army composition hoping to counter what his opponent had been doing recently. When the opponent had the proper counter to that strategy, he won the rest of the games easily.
