The word "win" is rarely used in chess. When it comes to winning, there is a big gap between the two sides, and there is no possibility of coincidence. For example, one side has two cars, two horses, two guns and two soldiers, and the other side has only one soldier. This is a win-win situation. No matter what the other side says, losing is inevitable. Example: You can win under normal circumstances, but you can't win under any circumstances. For example, artillery is superior to soldiers, and the whole case is superior to other soldiers. But this is not a victory. If soldiers cross the river in the same phase and are controlled by the opposing double shadow, it can be a coincidence or a situation. This is the difference between winning and winning. Sheng Qiao: Under normal circumstances, you can't win, but you can only win because the opponent's position is not good. For example, knights are better than people and elephants. Generally speaking, cavalry is an example, and scholars are the same. But if the defensive taxi position is not good, the cavalry side also has a chance to win. Because you can't win under normal circumstances, it's called "clever victory". This is the difference between success and example.
