CREATE TABLE table_name_13 (method VARCHAR, round VARCHAR, record VARCHAR)

What method was used in the match that went to round 1, and had a 6-3-1 record?
SELECT method FROM table_name_13 WHERE round = 1 AND record = "6-3-1"
SELECT "method" FROM "table_name_13" WHERE "6-3-1" = "record" AND "round" = 1
