Poker Strategies
After receiving pocket cards, you are immediately faced with a choice: play your cards and either raise or call the blinds, or fold.
Practice Matters
Looking at each situation from a more mathematical perspective
Looking at each situation from a more mathematical perspective and focusing on the goal at hand with each decision will make becoming more aggressive a lot easier to incorporate. You're betting or raising because it's the absolute best decision given the situation. Until this becomes nearly crystal clear, your natural lack of aggression and more passive personality will take reign in the decision-making process instead of the more mathematical / rational side. And if you don't think you excel at math, hyper focusing on hand ranges and working on equity using an equity calculator will improve this area for you over time. It will take work, but if your goal is to make the best decision possible in each situation, this is the area that will most improve the problem of not being aggressive enough.
When you are unsure which play is the correct play
When you are unsure which play is the correct play in a given situation, you'll lapse to your default psychology, which if it's too passive you're going to check too often. And as we said earlier, it's better to default to being too aggressive then too passive in poker. Naturally aggressive people tend to do better initially at online hold'em poker than naturally passive people, as long as they don't go too over board. However, once you have the proper understanding, and know which decision is the correct decision, you won't lapse into your default psychology.
