re: Poker & Hello! Any tips on how to play Holdem better?l
Welcome to CardsChat and thanks for your post!
Your question is a bit general, as asking how to play better in a tournament is much like asking which highway to take from Dallas to Cincinnati. There are many highways, many roads, many play styles, many decisions which go into a single tournament which contribute to your overall success.
As for which style to play in a tournament? The one which works for you. Generally, most experts advocate a TAG approach to the beginning stages of a tournament, and opening up your game as the tournament advances. A LAG approach can also be effective, but it is generally left best to those who have mastered the basics, as there is a higher risk involved with playing loose-aggressive.
