Annotated Game #109: How to play against your own opening?

It's always difficult to play against your own opening, psychologically speaking.  You normally will have faith in its superiority (or at least its preferability), the flip side of which is that you naturally will tend to dislike the other side's position type.  Of course strong players can often play both sides of an opening equally well, but that is one of the reasons why they are exceptional.  Overcoming a psychological bias and deeply understanding an opening's characteristics from both sides' perspectives, including the middlegame and endgame play that results, is I think a characteristic of mastery.

In the following game, played in the opening round of a tournament in the Slow Chess league, I face an early opening choice as White when my opponent replies with 1...c6.  Rather than transpose into more standard lines against my own defenses, I stick to an independent English Opening continuation that involves gambiting a pawn.  This is the first game that I have played with this line, so I'm pleased with it for training purposes, as well as content with the result.

One of my long-term flaws as a player has been being too materialistic, so learning to play more dynamically and with "compensation" is good for my chess.  In this game, the compensation for White is positional rather than in the form of a direct attack, although I was able to obtain some tactical play once Black castled queenside.  Houdini's assessment throughout was that White had full compensation for the pawn, which is useful validation of the line and my handling of it in this debut game.

FT: Young Norwegian takes world chess title

Magnus Carlsen's victory in the 2013 World Championship has deservedly received a great deal of press attention, including a front-page article in the Financial Times (FT).  The world's most influential grandmaster had this to say:
Kenneth Rogoff, a professor at Harvard, former chief economist at the International Monetary Fund and a chess grandmaster in his own right, told the FT: “Magnus was magnificent, showing enormous talent and a will to win, the likes of which can compare with the greatest in any sport.”
He added: “Carlsen has emerged as the most important public personality the chess world has known since the great American champion Bobby Fischer, he will draw many new devotees to the game.”
The "Lunch with the FT" article featuring Carlsen was also well worth the read, for those who have not seen it.

Training quote of the day #6: Yang Jwing-Ming

...Two monks were walking side by side down a muddy road when they came upon a large puddle which completely blocked the road.  A very beautiful lady in a lovely gown stood at the edge of the puddle, unable to go further without spoiling her clothes.
Without hesitation, one of the monks picked her up and carried her across the puddle, set her down on the other side, and continued on his way.  Many hours later when the two monks were preparing to camp for the night, the second monk turned to the first and said, "I can no longer hold this back, I'm quite angry at you! We are not supposed to look at women, particularly pretty ones, never mind touch them.  Why did you do that?"  The first monk replied, "Brother, I left the woman at the mud puddle; why are you still carrying her?"

Commentary - 2013 Russian Championship (Women's Final Round)

The final round of the 2013 Russian championship featured another Caro-Kann Advance similar to the round 4 game between Kosintseva and Kosteniuk previously analyzed.  White (Alina Kashlinskaya) plays a less challenging variation and Black (Daria Charochkina) eventually decides to liven up the game by creating a pawn structure imbalance on move 20, which features a passed c-pawn.  Black's 22nd move allows White to grab the initiative and make threats on the kingside, which eventually nets White a pawn.  Black from that point defends well, however, and shows how to use an active rook in the endgame, enabling her to hold the draw.
