AlphaZero shocks the world: Unbelievable Triple-Pawn Sacrifice

ChessAnalysisOpeningTacticsChess engine
In the popular Two Knights defence, there is a Triple-Pawn Sacrifice For A Deadly Bishop Pair Assault against the White King

Hi all

Another fascinating dynamic game shows Alphazero really playing in the spirit of the Romantic era, first with a well known counter gambit, but then extending the game to two more pawns. The resulting compensation is an impressive bishop pair but also another hidden asset - a 3rd rank which is clear of pawns that can be used to pivot a rook into the attack.

The game starts with the Two Knights variation

There is an invitation for White to play Ng5 here which Stockfish does play:

The best known antidote is a gambit variation

Qd1 is the equivalent of resignation - giving up a piece

So Why did Stockfish give up a piece? Lets highlight behind the scenes action now:

Key takeaway points

  • The Two Knights's defence goes into a very interesting gambit which is well known
  • Alphazero played two more pawn sacrifices, and Stockfish 8 only realised too late that the King attack was too powerful and just ended up giving up a piece
  • We cannot underestimate the power of dynamic attacking chess
