This is my serious annotation. This game comes from Philidor's Defense and reveals the power of opposite-side castling with a pawn storm. |

An interesting fact about this move is that in GK's database, after this move white wins most games continued from this opening. Must say something about it. |

Black is the first to break main line in this opening. On move 4! Maybe he should have learned his opening better if he wished to not get in trouble. |

Another strange move out of an unusual defense. What is the point of c6? White appears to have an advantage here with more development and space. He has also created a backwards pawn on d6 unless he plans to push with d5, but this wastes time. |

I did not want to lose some of my center with 7...Nxe4 8 Nxe4 d5, and I wanted to keep pressure on f7. |

This is a pointless move as f3 is already part of white's development in Philidor's Defense and this gives white tempo. |

I thought that black's plan was to hit my bishop on b3 with his knight so I provided an escape square, but a better plan for black is 10...Nc7 with ...d5 to remove his weakness. |

10... Nc5

My prediction comes through as black is not noticing the fact that he has a weakness on d6. |

An odd place to develop the queen. It now only has three spaces to move to an none of them attack. The only benefit from this move is putting a useless battery on the c8-h3 diagonal. |

What IS black doing with his pawns? He now has weaknesses on d6 AND c6 and his c pawn cannot move because of his knight. |

Pawn storm! this move has been waiting to happen for a while once the king castles kingside right into an onslaught. Notice that I am completely developed, I have a battery on the c1-h6 diagonal, my rooks are connected, and my light-squared bishop points directly at black's king. |

Maybe black was trying to open up his dark-squared bishop to attack the storm, but it doesn't help. |

An interesting move. Pushing my f-pawn removes a defender from g4 but is there a reason? |

Black takes the bait. |

Cutting the string that connected the queen and bishop in half! The bishop is now going to be stuck on the wrong side of the pawn chain. |

The bishop is the only defender of the kingside that is doing anything, and it seems logical to remove it. |

Exclam! A brilliant sacrifice! If 21...Kxg7, then 22 Qg5 Kh8 23 Qxf6 Kg8 24 Rg1 Bg6 25 fxg6 and forced mate is coming after 26 gxh7 Kxh7 27 Qg7#, or 22...Bg6 23 fxg6 and forced mate follows. A quicker death is 25...hxg6 26 Rxg6# all thanks to the bishop in the corner pinning the pawn. |

21... Rfg8

Since capure is bad, this is the only move that can stop the looming pressure on g7. |
