What do you do after E4

What do you do after E4? Well what about E5. Actually that is quite good. But I would like to talk about something different? What if you play D5. That would actually be quite a big mistake. Okay, E4 takes, then queen takes. The problem is that you brought your queen out too early. White can play Nc3. It attacks the queen and at the same time, it develops the knight. You can do that again with another piece if the other player does move to another. If you move the C pawn to any square, it would be okay. If you would move the C pawn I would like to move the pawn to C6 because the game seems good when you play a old opening that has been a good opening for a long time. If you want to know the name of the opening, the name would be Caro-Kann Defense. And if you want to know the name of the first opening I mentioned I think it was called the Centre Counter game.
