What is Razz?
The best way to think about razz is that it is seven-card stud in reverse. The high card is the bring-in, and on each street the lowest hand begins the betting. Typically this game tends to frustrate players as they can start with a great-looking low hand, only to catch multiple high cards or pairs. It's not a game that you will find spread very often in either cash game or tournament format in brick-and-mortar casinos. You can find plenty of razz online, but usually at low limits.
A typical joke between razz players is, "What is the average age of a razz player?" The answer? Deceased.
