Poker is a game of chance, but it also requires a fair amount of skill and psychology. The most important skill to master in poker is being able to read your opponents. You need to be able to pick up on little things like how they bet, how they react to certain cards and even the by-play between players.
You can do this by studying their eyes, idiosyncrasies and hand gestures. For example, if you notice that one player always calls your raises even though they have a weak hand, it is likely because they are trying to conceal their true strength from the rest of the table. A good poker player will also be able to read the table as a whole and use this information to their advantage.
Another important aspect of poker is being aggressive when it makes sense. This will help you build up pots and win more money. But be careful not to get too aggressive as this can lead to disaster. A good poker player will know how to balance aggression and make smart bluffs.
It is also crucial to play in position. This will allow you to open with more hands and put pressure on your opponent. For example, if you are in EP and your opponent checks to you with a marginal hand, it would be wise to check back and call. This will prevent you from over-committing to the pot and losing your chips.
