For this, you must be bigger than your opponent and be able to run in pursuit for three to five minutes, depending on the game length.
One Way to Always Win An OTB Blitz Game!!!

1. Bet with your opponent for a large sum of money, over 10$.
2. Set the time control to 3 minutes, the shorter the better.
3. When you shake hands, IMMEDIATLY GRAB YOU OPPONENT'S KING AND PRESS THE CLOCK ON YOUR FIRST MOVE.
4. Then grab your own king and RUN!
5. Notify that since your opponent is your only opponent, he is the only one who can tackle, etc me to get the kings back while your opponent's clock is running.
6. By definition, you have WON! "Taking you opponent's king and claiming a win" is a rulebook phrase.
Find a safe spot while your opponent pursues you. Only AFTER the game you can agree for that to never happen again, but you have won.

Well played, sir. Well played.

Lee Trevino did a similar technicality with golf rules. In a PGA tournament, he swapped his golf ball for a cleaner one; when an official confronted him, Trevino said "it was marked" - as he took out a marker from his pocket and "marked" the old ball. The rules of golf refer to "marked" meaning damaged - nevertheless Trevino got away with it.
Likewise, I may win a chess game by your method - as I am quick. The Flash and Sonic The Hedgehog finally pays off! The only problem I see is not them catching you; the only problem is them willingly paying off the bet after you win.
But your idea was worth a shot, right?

Well I will bring a friend to the board and ask him to determine the result, will explain the rules and the situation, will force opponent to pay!

unfortunatelly for you, that game can either be proclaimed your loss (plus, you likely won't get to play another during the same event), or the same player can ignore the fact that the king isn't physically there (he can maybe place anything in its spot, for simplicity) and simply make a move to get your clock started (while you're chasing chicken outside).
This method will probably not work in a real tournament, but you can use this when you are playing a game with someone you know for money!
