Remember, poker is a game of skill and strategy. The more you play and learn, the better you will become. Generally, novice players call bets way too often. If you're new to poker the most profitable strategy that will get you into the least trouble is to play (ultra) tight-agressive.

It's primarily a skill game, although luck plays a huge role. In any single given hand, luck is the predominant factor in who will win or lose. However, poker players don't play a single hand. They play hand after hand after hand & and overall, skill dominates.
