i hate the coordinates on the chessboard, but play your knight to defend your king pawn(e4 or e5). Then move your knight to attack the opponent's king pawn. then move your bishop somewhere to attack the other dudes knight. sacrifice your bishop for their knights, since i think knights are better than bishops. thats my opening i ALWAYS play, unless i feel really bored. i think its called the four knight opening.

Out of every double KIng's pawn opening, the Scotch makes the most sense to me. When I used to play it, I would play 2.d4. If you have any specific questions, shoot me a message.

You can't go wrong learning the Ruy Lopez. One GM said that if you don't know how to play it, then you don't know much about chess.
(According to that reasoning, I don't know anything about chess because the Ruy Lopez never occurs in my games.)
From the white side, play the Ruy Lopez against e4 e5. If you learn that and something to play against the Sicilian, then you'll be ok.
Or you could be like me, and switch to d4. :-)
HI pplz, can you please recommend me an opening other than guicco piano, fried liver, or ruy lopez? I am looking to try out something different, the only idea i currently have is the scotch game.
