I think, a tight game at the early stage of any tournament is not the best tactic of the game. Of course, when you get a new table (new opponents), you can't see and know the full statistics of the players, but the early stage is, when the blinds allow you to play much wider and more aggressively, so this is a great opportunity to increase your pot - using these opportunities. It is necessary to conduct a more open game and a wide game in order to collect more information and play average hands. But, when you play a lot of hands, not every hand will be for you, so do not worry about the possibility of folding and calmly wait for the next not bad hand to play. About the risk at the table, this is absolutely true, you should not go to everything, when you have a very strong hand, because the initial stage is very dangerous and unpredictable and the strength of the top pairs is very reduced..
