Third conditional

The third conditional is used to talk about things which did not happen in the past. It is often used to express criticism or regret:

If you had driven more carefully, you would not have had an accident.	Criticism: You had an accident because you didn't drive carefully enough.
If we had played a little better, we could have won the game.	Regret: We didn't play well, so we lost the game.
