In almost all the open tournaments in the world, there would always be an additional time in the later game once both players had already passed a specific threshold. The normal case was 30 minutes additional time once both players passed the 40th move, with 30 30-second increment in each move. This additional time was there to give players more time for the complex and time-consuming endgame phase, ensuring they had sufficient time to play these critical positions well rather than being forced to make mistakes under pressure due to limited clock time.
After all, the endgame phase was no joke. It was a different beast, a completely different battlefield. It was a cruel stage full of landmines, where one mistaken step was enough to blow even the best player in the world.
