All amateurs with the exception of aged based divisions, like Juniors or Masters and older, compete in divisions based on rating levels. You may not play in a lower division if your rating is above a certain number. Current Amateur divisional ratings lines are; MA1 if 935+, MA2 <935, MA3 <900, MA4 <850 and Am Women; FA1 if 800+, FA2 <800, FA3 <750 (from the Player Division Table.) In addition, there are ratings events where everyone – Ams and Pros – play in a division based on their rating. Players are always allowed to enter divisions even higher than their current rating, just never below.
