What are the first names of the different drivers who won in position 1 as driver standing and had more than 20 points?
SELECT DISTINCT T1.forename FROM drivers AS T1 JOIN driverstandings AS T2 ON T1.driverid = T2.driverid WHERE T2.position = 1 AND T2.wins = 1 AND T2.points > 20
first names of drivers = T1.forename; won in position 1 as driver standing = T2.position = 1; had more than 20 points = T2.points > 20; wins = T2.wins = 1; DISTINCT is used to select different drivers.
