When is it good for the opponent to trade on QB4(c4 in this position) and what should the KI player do about it? The books I have on KID and KIA don't say anything about it, probably most master level players avoid this kind of position against KIA and KID. It is difficult for the opponent to stir up play on the queenside, and even more difficult after the trade.
To explore this position, I switched the colors, because there are more KID games than KIA. I opened the database window (Application Menu=>Open=>Open Database). On the large database that comes with Fritz (database window Application Menu=>Database.cbh), I filtered games looking for this position:
In the loss (Morozov vs Khruschiov at Peterhof round 5 2009.08.05), black supports the c5 pawn with b6 before white attacks it, and allows white to get a passed pawn on e5 to pair with the d5 pawn. White plays very actively, Black less so. White trades off his bad bishop for the Ng5.
Ideas from the wins:
- transfer rook Ra3-f3
- blockade d-pawn with a Nd3
- retreat Ng5 to h3 when kicked which supports f4 and allows transfer to d3 via f2
- blockade with Bd3(big pawn?).
- Opponent blocks the rook transfer by attacking c-pawn, but that allows advance of the f-pawn and blockade by knight on d-file.
Now that I have a better idea of what constitutes a good position after Be6xNc4. Now I need to go through the game from move 8 with that in mind and make comments, until those plans are obsolete.
From this position before move 8:
To finish, I go through the game in Infinite Analysis mode, trying to understand Fritz's suggestions, extending some suggestions into variations and deleting others. Then I add explanations in English as I can.
