"善弈者通盘无妙手"—《棋经》
高手下棋,不靠奇招,靠每一步略胜积累胜率。
如李昌镐只求半目胜,即每手51%的胜率。
如费德勒在 2024 达特茅斯毕业演讲上说:“In the 1,526 singles matches I played in my career, I won almost 80% of those matches. Now I have a question for you: What percentage of points do you think I won in those matches? Only 54%.”即赢了近 80%的比赛,但每一次击球的得分概率只有 54%。
