Today, chess programs have become so good that even grandmasters sometimes struggle to understand the logic behind some of their moves. In chess magazines, one often sees comments from top players such as “My silicon friend says I should have moved my King instead of my Queen, but I still think I played the best ‘human’ move.”
拥有更强大的处理器，硅棋手的计算能力如此之快以至于短期战术性计算和长期战略规划的差异变得很模糊。与此同时，计算机程序开始挖掘象棋冠军（象棋界最高头衔）比赛中的数据库，使用人类比赛结果来推测哪些象棋步法取胜的可能性最大。很快，比较明确的事实是：即便是人类最好的象棋手也鲜有机会比偶尔的和局做得好。
