CREATE TABLE "preliminary" (
  "rank" real,
  "country" text,
  "athlete" text,
  "technical" real,
  "free" real,
  "total" real
);

Question: what is the most free when the total is 81.167 and the rank is higher than 23?
SQL: SELECT MAX("free") FROM "preliminary" WHERE "total"=81.167 AND "rank">23;
