Crunchyroll testing AI for subtitling

Translator's note:

In the intricate world of chess, where strategy and tactics intertwine, **making an illegal move** can happen for various reasons. Let's explore some of them:

1. **Accidental Oversight**: Often, players unintentionally make illegal moves due to oversight or lack of awareness. Perhaps they didn't realize their king was in check or misunderstood a piece's allowed movements.

2. **Pressure and Nerves**: In high-stakes games, nerves can play tricks on even the most seasoned players. The pressure to perform well might lead to hasty decisions, resulting in an inadvertent illegal move.

3. **Complexity of Rules**: Chess has a plethora of rules governing piece movements, castling, en passant captures, and pawn promotion. Amidst this complexity, players might inadvertently violate a rule.

4. **Psychological Tactics**: Some players intentionally make illegal moves as a psychological ploy. They hope to confuse or distract their opponent, disrupting their focus and rhythm.

5. **Desperation**: When faced with a losing position, a player might resort to an illegal move out of desperation. They hope their opponent won't notice, or perhaps they're banking on insufficient mating material to salvage a draw.

Remember, the consequences of an illegal move vary:
- **First Offense**: The opponent gains extra time (two minutes in standard games, one minute in blitz).
- **Second Offense**: The player loses the game.
- **Insufficient Mating Material**: If the opponent lacks enough pieces to checkmate, the game is drawn.

So, whether accidental or strategic, illegal moves add an intriguing layer to the chess battlefield.
