A Contribution to the Theory of Queen's Gambit Accepted

"Black Russian"
No. 312 Squadron RAF
As I have already informed you, The Grantham Kings Correspondence Chess Team plays on several servers. On one of them - SchemingMind.com - I was paired with a strong player with mysterious nickname "BlackRussian". Despite the fact that I am old enough to be well educated in foolishnesses and pleasures of life, this time I failed completely. Matured man like me has never heard of a cocktail named Black Russian! What a shame.
Well, to be honest with you, my nickname also rises some questions. Why Spearhead SQ312
I try to give you just a little hint - it has something to do with the Battle of Britain. Yes, No. 312 Czechoslovak Fighter Squadron of RAF, with its fighting Latin motto "Non Multi Sed Multa" i.e. "Not much, but many".
The game we have played was really interesting. 
First, it is a small contribution to the theory of the Queen's Gambit Accepted
Second, it is an example of a complex technical ending
We have followed theory up to the move 20 when my opponent came up with a novelty. Then the game went into the King, Queen and Pawns ending where White was pawn up. The problem was how to turn the advantage into the victory. This technical ending was far from being easy to win. Hope you will like it.

There were several moments in this game which deserve some diagrams and special attention. 

No.1: Critical opening position after 14.Ng5! The only move which enables to continue even in worse position is 14...Rf8.


No.2: White has material advantage but is it enough to win?


No.3: White King lost his fortress. The problem White has to face to is where to hide his King and how to protect him from annoying checks?


No.4: Final position. White would win by following fashion: 

72... Qxa6 73. hxg5+ Kh5 74. f4 Qc4 75.  Kg3 Qe6 76. Qf3+ Kg6 77. Qd3+ Kg7 78. Kh4 Qe1+ 79. Kg4 Qg1+ 80. Kf5 Qc5+ 81. Ke6 Qc6+ 82. Qd6 Qc4+ 83. Kd7 Qb5+ 84. Ke7 Qb7+ 85. Qd7 Qe4+ 86. Kd6+ Kf8 87. Qd8+ Kg7 88. Qe7+ 1-0
