Part 3: The Breakthrough (2015-2016)

**Verse 1:** In the days when the game changed its course, AlphaGo rose, a silent force. Against the champion, with no remorse, A victory path, it would endorse. **Pre-Chorus:** On the board where stones lay cast, A battle between the future and past. With each move, a shadow cast, AI’s triumph, vast and vast. **Chorus:** Beyond the board, a new dawn breaks, With every move that AlphaGo makes. A world of possibilities it awakes, In the realm of AI, the earth quakes. **Verse 2:** Lee Sedol, a master of his art, Faced a challenger off the chart. A machine with no heart, Yet, in strategy, it played its part. **Pre-Chorus:** Move by move, the game unfolds, In this tale that history holds. A future where AI beholds, More than stories, more than molds. **Chorus:** Beyond the board, in the silent fray, AlphaGo leads the way. A testament to AI's sway, In the dance of minds, it'll stay.
