We know from last time that you should not choose a dominated strategy, and we also know we probably aren't going to choose a weakly dominated strategy, and we also know that you should put yourself in other people's shoes and figure out that they're not going to play strongly or strictly or weakly dominated strategies.

上节课我们学到了,不要采用劣势策略,然后今天我们学到了,我们有时可能不会选择弱劣势策略,我们还学会了站在别人立场上思考,然后推测出他们不会选择,严格劣势策略或弱劣势则略
