Playing well and having a good chess understanding is what every chess player is looking for. However, when it comes to practice this is not the only thing that matters. While when you are training there is no time limit on the exercises you solve and the themes that your learn, during a tournament you have a very stressing piece of equipment at the side of the board – a chess clock. This means that even if your play is good, bad management of the time you spend on your moves will eventually lead to time trouble when bad moves can easily happen.
