It could also be the range from UTG (under the gun, the position that is first to act in a hand). It isn't generally recommended to play as few hands, but can be a good way to start in poker if you're a beginner (only playing strong hands makes the decisions easier).

This chart displays a 10% range in pre-flop: A small range has high ”density” for hands such as AQ and AK. The narrower the range of the opponent, the higher the risk for strong hands. Notice that a 10% range, for example, isn't the same as 10% of the the hands displayed in the charts – there are more combinations of some hands (see Number of combinations for different hand categories), therefore, the marked hands versus unmarked in the chart doesn't coincide with the percent numbers. The charts are categorized by the percentage of hands. For your help to visualize all possible starting hands, these ranges can be very helpful. Instead of making up your mind from time to time, you should have a constant plan. When you play poker, you should be relative consistent regarding which starting hands you play in different situations.
