chess styles
First, in most positions there isn't an objectively best move. In some cases you have to make a choice between taking the game into two different kinds of positions. In this case, knowing whether you tend to do better in a complex tactical position or a position that demands slow positional manoevering could be important in deciding what move to play.
Second, if you're going to adopt a particular opening system it's best to pick one that fits your style. Otherwise you'll wind up in middle game positions that you don't play as well as middle game positions from other opening systems.
Having said that, if you're below expert level, these considerations are far far less important than consistently making good moves and accurately calculating tactics. Nearly all games below expert level are decided by mistakes rather than good moves that don't fit the players style.
