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_59336 ( "White" text, "Black" text, "Year" real, "Result" text, "Moves" real, "Tournament" text, "Opening" text )

### Question ###
What is Opening, when White is Kramnik, when Year is less than 2001, and when Tournament is 'Siemens Giants'?

SELECT "Opening" FROM table_59336 WHERE "White" = 'kramnik' AND "Year" < '2001' AND "Tournament" = 'siemens giants'
