So what did William the Conqueror do?

那么威廉一世当时是怎么做的呢
He burned his ships.

他把船都烧掉了
So let's now make this game a little bit more

下面我们把这个博弈还原得
like the real historical situation,

更接近史实一些
here's a move that William the Conqueror, the King of the Normans can do.

这是威廉一世即诺曼底国王的选择
He can either not burn his ships or he can burn them.

他可以选择是否要烧掉船只
If he burns them then the game is rather different.

但如果烧了博弈就大不相同了
Once again, the Saxons can decide whether to fight or run away,

当然萨克逊人可以选择抵抗还是逃跑
but now the Normans really don't have any choice.

但诺是曼底人却没有选择的余地了
They have to stay and fight

他们只能选择继续战斗
because swimming back to France wearing armor is difficult.

因为穿着盔甲游回法国非常不现实
So the payoffs become (0,0) and (2,1) as before.

因此收益仍是(0, 0)和(2, 1)
