CREATE TABLE table_name_86 (laps INT, grid VARCHAR, time VARCHAR)

With a Grid less than 15, and a Time of +52.833, what is the highest number of Laps?
SELECT MAX(laps) FROM table_name_86 WHERE grid < 15 AND time = "+52.833"
SELECT MAX("laps") FROM "table_name_86" WHERE "+52.833" = "time" AND "grid" < 15
