One of the most important (and exciting) things about poker is that no two situations are the same. You can have the same exact two cards twice in a row, but chances are the decisions you make will be very different depending on what the flop is, how many players are involved, your position and everything else that comes into play. One of the most influential factors that can determine a fold, call or re-raise is the type of opponent you’re facing. We’ve all played against the guy (or sometimes girl) who is involved in every single pot. He or she plays hands you wouldn’t dream of playing; raising with 5-8 offsuit.
