Table schema:
CREATE TABLE table_name_6 (to_par_ VARCHAR, a_ VARCHAR, year VARCHAR, champion VARCHAR)

Question: What was the To Par [a] when Charles Coody Category:Articles with hCards was champion and the year was earlier than 1973?
SQL: SELECT to_par_[a_] FROM table_name_6 WHERE year < 1973 AND champion = "charles coody category:articles with hcards"
