Most Tic-Tac-Toe losses happen from pattern mistakes, not bad luck. If you learn a few high-value patterns and apply them consistently, your results improve immediately.
First Rule: Never Skip Threat Check
Before every move, run this sequence:

Safe Defense When You Are Under Pressure

Defensive checklist

Common Pattern Mistakes
Mistake 1: Chasing your own line while opponent has a direct threat

Mistake 3: Playing too fast in move 5-7
Fix: Mid-game is where forks appear; take extra time here.
