Everyone wants to learn about chess strategy. Players believe that if they learn more about this magic thing called “strategy” they’ll win every single game. But what chess strategy really is? Is it attack or defense, style of playing or evaluation of positions, set of rules, or tactics? No, my friend, I’m not trying to confuse you, just to show that chess strategy covers all of the above to some extent.
Wikipedia defines chess strategy as an evaluation of chess positions and setting up goals and long-term tactics for future play.
