Understand the boundary
The ITF lists the Australian Open, Roland Garros, Wimbledon and US Open. Roland Garros is the French Open; these are names for one tournament, not two separate majors. A “Grand Slam” can also describe winning all four, but this question asks for an individual event.

Choose an answer for your goal
Our prepared aliases accept French Open for Roland Garros, AO for Australian Open and The Championships for Wimbledon. They preserve the same canonical answer and fixed points. Roland Garros earns 80 points and Australian Open 65. The presence of “Open” in a title does not make any other event a major.
Worked examples — reveals answers
- French Open · Accepted
- An explicit alias for Roland Garros, worth the same 80 fixed points.

- ATP Finals · Outside this set
- A professional event, but not one of the four Grand Slam tournaments listed by the ITF.
Practice the distinction
Check French Open and Paris. One is a tournament alias; the other is its host city. Then switch to the Grand Slam host-cities question and explain why the requested answer type changes.
