Harvey: Rules? In a knife fight?! No rules! [Butch immediately kicks Harvey in the groin]
Butch: Well, if there ain't going to be any rules, let's get the fight started. Someone count 1-2-3 go.
Sundance: 1-2-3 go! [Butch finishes off a helpless Harvey]
In any competition, making the first move helps. Naturally, the Combat Pragmatists of the world and those who believe in fighting dirty often like to take that a step further, by intentionally getting in a first blow before a competition is even supposed to start so they have the advantage.
While an Anti-Hero may be able to get away with this, it's generally more of a villain move. After all, heroes can only get away with creeping out in front of a race's starting line or hitting an opponent that isn't ready in sparring so many times before they stop looking like a hero.
If the person doing it loses anyway, it's because Cheaters Never Prosper.
The "Why Wait?" Combatant has a lot of similarities to this tactic (and can occasionally overlap), but that sort of combatant often just wants to fight, while this one is fighting dirty to win.
Not to be confused with False Start.
- KonoSuba: done by Kazuma when Mitsurugi challenges him to a duel over his perceived mistreatment of Aqua. Kazuma immediately says "OkayIacceptGO!" and attacks. Mitsurugi is so caught off guard that he's unable to properly defend himself, despite having far superior equipment.
- The live action version of Initial D has Itsuki starting before the countdown finishes during his face with Takeshi Nazakato. Being a casual racer, it doesn't help that much when he crashes.

- In The Quick and the Dead, a Quick Draw tournament is held where both contestants start to draw when the town clock chimes the hour.

- Butch Cassidy and the Sundance Kid. Butch is about to be in a knife fight with fellow gang member Harvey, who is challenging Butch to be leader of the gang. Butch tells the others that the fight isn't starting yet and approaches Harvey, pretending to be concerned about what rules they'll fight under. When Harvey protests that there are no such things as rules in a knife fight, Butch immediately disables Harvey with a Groin Attack, then instructs his other men to officially start the fight, then finishes off Harvey.
- The Man with the Golden Gun: James Bond is kidnapped by Hai Fat and taken to a martial arts school, where he is forced to fight the students.

The next contestant only bows partway, keeping his eye on Bond the whole time.

Danaher makes a show of raising his arms and announcing to the watching crowd, "Marquis of Queensbury! Marquis of Queensbury!" meaning that he intends to fight in accordance with the rules of boxing, as set forth by the Marquis of Queensbury. Sean Thornton, wanting to signify the same intention, mimics Danaher's performance. Thornton is still gesturing to the crowd when Danaher wallops him with right hook that sends Thornton reeling.
- Escape from L.A. has Snake in a seemingly unwinnable situation of a 4 to 1 gun duel, so he challenges the four gunmen to a duel where "No one draws until this (an aluminum can he finds) hits the ground. You ready?" After Snake throws up the can, he immediately shoots the four gunmen dead with his two pistols. After the can lands, "Draw".

He then calls and gets his down payment, then reveals that he's killed the target just moments ago.

- In the same episode, Tarrant becomes the Champion and has to fight on a killing ground chosen at random. Orac hacks into the gaming computer to find out the environment Tarrant is about to enter, so he has a few crucial seconds to prepare an ambush. In fairness, the other side is already cheating by using an android as their player.
- Game of Thrones: After Jaime Lannister loses his sword hand, he is forced to retrain his other hand, taking up sparring lessons with Bronn. Bronn, being a proud Combat Pragmatist, starts the match by punching Jaime in the face before he's even ready. Jaime calls him out on cheating, but Bronn just shrugs.
- Oh so often, usually with the Heel attacking the Face before the bell. Technically illegal, but it happens so often that it's usually completely ignored by the referees nowadays, who just signal for the opening bell after the first guy gets in the first shot. Another version, taken a little more seriously, is when someone is attacked backstage before the match.
- In a fan participation run before WrestleMania 4, Mr. Fuji, wearing a full tuxedo, started running at the "On your mark" call, while everyone else waited for "Go." Of course, he was soon overtaken by the real racers, and then got into a push cart and had someone push him all the way to the finish line.

- In Nikolai's Trains, Neow-Neow challenges Nikolai to a race to see who has the faster, stronger, and better train. Just before the starter fires his pistol, Neow-Neow releases his engine's brakes and races away. This backfires immensely, as the lineman had neglected to change the switch, resulting in Neow-Neow's train being diverted onto a siding, where it crashes against a bumper and falls to pieces. Nikolai waits patiently while Neow-Neow has his train fixed, and restarts the race when Neow-Neow's train is back together. This time, Neow-Neow agrees to play fairly for the rest of the race.
- All over the place in TF2 - Duel Failure (a Jerma-Star crossover.) The two of them try to arrange a revolver duel, but both of them keep trying to betray each other. The first time, Jerma lies that he won't attack STAR_ as he approaches the duel zone, only to fire... and completely miss. The second time, STAR_ kills Jerma in the middle of explaining the rules. Then lastly, when the two of them arrange the rules to be to face away, take ten steps, and then turn to shoot, STAR_ tries to cheat by turning on step 3, except Jerma never turned at all and shoots him the instant STAR_ tries.
- In Undertale, Sans does this, attacking the player mid-dialogue — and taking the first turn, which the enemies in Undertale otherwise never do. If the player survives the attack, he wonders out loud why people don't always start off with their strongest attacks.

- The LEGO website used to have a flash game based on its Drome Racers line wherein you could set your start to go on green, yellow, or red.

Tommy is given the job of waving the flag (which consists of a pair of underwear on a stick). Angelica drives off before he waves the flag, which leads to this exchange:
Lil: Hey! That was cheating!
Tommy: Nah, Angelica told me, she was opposed to go right before the flag was waved, and Susie's opposed to right after.
Phil: Oh. Well, as long as it wasn't cheating.
- Mike, Lu & Og: In "The Mother of All Marathons," Mike and Lu have a sprint race and Lu starts before Mike says "Go." Mike still wins because she's more athletic.
- The Land Rush of 1889 had a number of people hide out in unoccupied lands of what is now Oklahoma to claim the land before the Land Rush officially started. Because they got there sooner than the others, they were referred to as "Sooners." This is why Oklahoma's state nickname is "The Sooner State."
- The shortest professional boxing match that ended by knockout went 10 1/2 seconds including the 10 count. It is estimated that Aurele Catoure was more than halfway across the ring before the opening bell sounded; he punched & knocked out Ralph Walton while Walton was still adjusting his mouthpiece.
