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 ###

### Question ###
What is the lowest Semidoubles, when Doubles, II Class is 18, and when Total is less than 164?

SELECT MIN("Semidoubles") FROM table_40515 WHERE "Doubles, II Class" = '18' AND "Total" < '164'
