AlphaZero shocks the world: Unbelievable Triple-Pawn Sacrifice
In the popular Two Knights defence, there is a Triple-Pawn Sacrifice For A Deadly Bishop Pair Assault against the White KingHi 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:

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
