White attacks the knight. |

Before moving the knight, black does this exchange. It is a good idea generally to exchange pieces, but not pawns, if materially ahead, but in this case it is slightly questionable as the Bishop on g4 was more active than the knight on e2. |

White of course back, clearly the best move. |

Now if black had played this a move previously, white would have had difficulty in defending the pawn on c2 - in fact it would have been impossible, and so to avoid losing the c pawn white would have had to take the knight on a3 with her bishop. As it is, white has a strong reply. |

An excellent move by white! There is no a real danger that black will lose his extra piece. For instance, 13. ...Ba5? 14. Bxa3! There was however an equally good move in this position for white, namely 13. Bh6! with the threat of Qxg7 mate! Black can defend with 13...Ne8! and then white can play 14. c3 |

This unfortunately is a mistake. 14. Qd3 was called for, keeping the double protection of knight and queen on the pawn on c3. |

Black now has material advantage of bishop and two pawns. |

Clever move by black, protecting the bishop and attacking the queen. |

Queen has to move again. White is cleverly planning an attack on g7. |

Black attacks the rook, a good idea, but there was a much better move at black's disposal here, namely 16. Qf6! attacking the rook on a1 and also nullifying white's attempted to attack the black king. |

An excellent move by white, threatening mate. |

Knight takes the rook. |

White correctly takes back the more active bishop, rather than the knight on a1 which is trapped behind enemy lines and lost anyway. |

The knight tries to come out. |

A good square to put the queen where it attacks the knight. |

Black develops the queen. |
