In the middle and the end of a chess game, there are visible consequences to almost every move you can make, there are more contraints limiting what is logical to move, and it is fairly straightforward to see what you did wrong when you analyze the game.
At the beginning of the game, it seems like there is a tremendous number of possible ways a game could progress--and not very many of the moves have any immediately tangible consequences. Because of this, I usually have no idea what I should do in the beginning of a game.
Are there any things I should be thinking about at the beginning? Up to date, I've just been moving pieces haphazardly until what I need to do becomes obvious.
