How does your rating affect what division you can enter?

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.
