Simply pick your two cards and whether or not they are of the same suit. Then select the number of opponents. Preflop Odds will show you the % of times your hand will win or tie. Odds are calculated using every possible combination of cards. Player styles, betting strategies and other real world conditions are not considered. Therefore the odds given may not represent conditions at a real world poker table. Preflop odds is meant as a research tool to guide you to the strength of your hand preflop. It will help you to understand how to adjust your play as the number of players at a table dwindles. You may be suprised by the strength of a hand in a given situation. For example 76 suited against 2 opponents fares better than AA against 9.
