One thing that can really set a amateur from a pro when it comes to poker is the ability to read your opponent. Picking up on "tells" from your opponent can be the key from folding your hand or making that extra bet to take the pot. One of the main keys they factor on is that you need to take into affect the possible strength of your opponents hand and your position on that opponent. Good players do not win on a consistent basis just from getting good hands. While it takes much practice if you develop good reading skills on your opponents it can take you a long way in poker.
