re: Poker & Tight Player Needs Tips
If you haven't started taking notes on players, start now. Write notes such as:
Folded to a 3-Flush board.
Played KK passively
Check/raised Top 2 pair
When you have notes on the majority table (ie: reads) and not just TAG, LAG then you can start to loosen up. You will be able to force these people off of hands.
Personally, besides the obvious short-stacked, short-handed strategies, I feel that it is much better to play tight until you feel you have the advantage.
