Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_name_69 ( tries_for INTEGER, points_diff VARCHAR, points_against VARCHAR, tries_against VARCHAR )

### Question ###
Which Tries for has Points against larger than 87, and Tries against smaller than 28, and Points diff of +63?

### Accurate SQL ###

SELECT AVG(tries_for) FROM table_name_69 WHERE points_against > 87 AND tries_against < 28 AND points_diff = "+63"
