Stockfish Obliterates AlphaZero in a Violent Alekhine Defense Attack

This game is not slow. It is not subtle. It is pure domination through pressure. Stockfish turns AlphaZero’s Alekhine Defense into a structural disaster and never allows recovery.

Opening Phase: Provocation Backfires (Moves 1–15)

The Alekhine Defense invites White to overextend—but here, that plan completely fails.

After 3...Nxc3 and 4...d5, the center opens early. But Black makes a critical mistake:

12... Nc6 (repeating moves)

This loss of time gives Stockfish exactly what it wants—space, control, and initiative.

Then comes the key moment:

16. e6!

This is not just a pawn push. This is a positional lock. Black’s pieces are pushed back into passive squares.

Key Insight: When your pieces are restricted, tactics will eventually destroy you.

Middlegame: Structural Collapse (Moves 16–35)

Stockfish expands on both sides:

• b4–b5 crushing queenside
• g4 opening kingside

AlphaZero tries to react with ...f5, but this only weakens its own position.

Then comes a critical sequence:

24... Rdxe6 25. Rxe6 Rxe6 26. gxf5

Black’s pawn structure is completely shattered. Every weakness is permanent.

Turning Point: After 27. Nxf5, White is simply better everywhere.

Domination Phase: No Counterplay Allowed (Moves 36–60)

Stockfish now plays like a python—slowly squeezing.

• Re1 controls center
• Ne4–Nf2 improves pieces
• f5! breaks the position open

AlphaZero tries to fight back with Qg3 and rook activity, but Stockfish calmly neutralizes everything:

39. Qxg3+!

All attacking chances disappear instantly.

Reality: When your attack gets traded off, your weaknesses remain forever.

Endgame: Passed Pawns Decide Everything (Moves 61–76)

Now comes the final phase—and it’s brutal.

Stockfish creates multiple unstoppable threats:

• f-pawn advance (f6, f7)
• h-pawn march (h5–h6–h7)
• a-pawn promotion

AlphaZero is overwhelmed. It cannot stop all threats at once.

The final sequence is clean and inevitable:

76. Qd5#

A precise checkmate—no drama, just complete control.

Key Lessons from This Game

Final Verdict

AlphaZero tried to provoke—but Stockfish turned that provocation into punishment.

This was not just a win. This was a systematic destruction from opening to checkmate.
