A: That depends a lot on your current skill level. If you are a complete beginner it would be to play very conservatively, fold most of your hands without making any bets. If you are a bit further along it could be to start learning some of the more significant strategic approaches to the game.
Poker is a card game in which players place bets into a pot prior to seeing their cards. Each player can call that bet, raise it or drop (fold) their hand at any point during the betting round. The highest ranked hand wins the pot. Bets are only placed into the pot if players believe they have positive expected value or they are trying to bluff other players for various strategic reasons.
The best way to improve your poker skills is to spend as much time studying away from the table as you do at it. Reading poker blogs, articles, books by professional poker players, and watching poker videos are all great ways to get a better understanding of the game and how to play it well.
Another thing you should focus on is studying other players to learn their tells (eye movements, idiosyncrasies, betting behavior etc.). This will help you make more educated decisions on when to call or raise against them. Another very important aspect of poker is learning about ranges. This is a mathematical concept that helps you figure out the range of cards that an opponent can have in their hand. This will give you a better idea of how likely they are to have a certain type of hand and what your chances are of beating it.
