Van Alen called his innovation a "tiebreaker", and he actually proposed two different kinds or versions of it: best-five-of-nine-points tiebreaker and best-seven-of-12-points tiebreaker. The first lasts a maximum of 9 points, and awards victory in the set to whichever player or team first reaches 5 points – even if the other player or team already has 4; the margin of victory can be a single point. Because this "9-point" tiebreaker must end after a maximum of 9 points, even if neither player or team has a 2-point (or greater) margin, Van Alen also called it a "sudden-death tiebreaker" (If and when the score reached four points all, both players faced simultaneous set point and/or match point.). This type of tiebreaker had its Grand Slam debut at 1970 US Open and was employed there until 1974. Apart from being used for 5 years at US Open it was also used 1 year at Wimbledon and for a while on the Virginia Slims circuit and in American Colleges.
The score of a complete match may be given simply by sets won, or with the scores in each set given separately. In either case, the match winner's score is stated first. In the former, shorter form, a match might be listed as 3–1 (i.e. three sets to one). In the latter form, this same match might be further described as "7–5, 6–7(4–7), 6–4, 7–6(8–6)". (As noted above, an alternate form of writing the tiebreak score lists only the loser's score—e.g., "7–6(6)" for the fourth set in the example.) This match was won three sets to one, with the match loser winning the second set on a tiebreaker. The numbers in parentheses, normally included in printed scorelines but omitted when spoken, indicate the duration of the tiebreaker following a given set. Here, the match winner lost the second-set tiebreaker 7–4 and won the fourth-set tiebreaker 8–6.
"Tennis Court" received positive reviews from music critics, with some highlighting the song's production and lyrical content. The single was a commercial success in Oceania, reaching number one in New Zealand and number 20 in Australia. It received platinum certification in Canada, double platinum certification in New Zealand and triple platinum certification in Australia. "Tennis Court" achieved modest chart success throughout Europe and North America, entering at low-tier positions on charts in Canada, Germany, the UK and the US. Joel Kefali directed the song's accompanying music video, a one shot in which Lorde stares to the camera throughout. "Tennis Court" was included on the set list of Lorde's Pure Heroine Tour (2013–14).
