24... Qc3+
|
Black seeks to buy a valuable tempo with the check to deal with the threats created by the White knight. |

Moving the Rook instead of the bishop would not have been any better, i.e. 25...Rxe7 26.Bxe7 or 25...Reb8 26.Nxf5 |

26. Qg4
|
White is aiming at e6, since Qe6+ is lethal for Black. |

|
|
|
26... Nc5
|
Defending against both Qe6+ and Nxb7. |

|

27. Rc1
|
Skewering the Queen and the knight at c5. |

|
|
|
27... Qb3
|
Black is banking everything on the passed pawn at a3, ready to give up the knight if it will buy another tempo. |

Now b7 is onyl again vulnerable, but White has to take extreme care due to the impending threats with ...a2 and ...a1=Q |

|
|
|
28... a2
|
The threat is a1=Q+ |

Probably the only move, White must be willing to give up the extra material in order the neutralize Black's attack. Now 29...a1=Q 30.Rxa1 Bxa1 31.Nd2 Qd5 32.N2c4 Nd7 33.Nxe8 Rxe8 34.Ne3 Qe5 35.Qc4+ looks good for White. |

Probably a mistake, since Black now loses more material. A better try might have been a1=Q, leading to 30.Rxa1 Bxa1 31.Nd2 Qd5 32.N2c4 Nd7 33.Nxe8 Rxe8 34.Ne3 Qe5 35.Qc4+ Kh8, which gains a rook and loses two pawns by comparison. White still has a better position but it is not as clear cut. |

Opening up a line of defense for the Queen to defend the important bishop at e2, which is under some pressure from Black. |

|

Black now has a very tangible threat: ...a1=Q |

White threatens mate and creates an absolute pin (the strongest kind of pin!) on g7. |

|
|
|
32... Qf7
|
Black must consolidate and guard g7 which is currently the focal point of White's attack. |

Removing the promotion threat and banking on the power of the absolute pin - the white bishop is immune on a1 as long as the g7 bishop remains pinned to the king. |

|
|
|
33... Qxe7
|
With the e7 finally undefended Black jumps on the opportunity to capture it, adding to the pressure on e2. Also worth considering was the prophylactic move ...Kh8 |

|

White consolidates king safety, adding another defender to e2 and creating discovery check threats. |

|
|
|
34... Bd3

Black pins the bishop at e2 and adds even more pressure on it. 35.Bxd3?? Qxe1# |

|

White creates its own threats with which Black must deal immediately. Both the Queen and bishop at g7 are under attack, and the pressure on the h-file is also mounting. So in order to alleviate the pressure Black must give up some more material. |

|
|
|
35... Bxe2+ 36. Rxe2 Qxe2+ 37. Qxe2 Rxe2 38. Kxe2
|
The dust has settled, and White find itself up a piece with the threat on a2 nearly neutralized. This endgame is easily won for White. |
