Winning by better understanding the plan behind a position

In 2008, my daughter Donna played the European girls championships in Montenegro. In round 7 she was paired against one of the favorites, Keti Tsatsalashvelli from Georgia. Keti has become a Woman Grand Master and makes regular appearances as a chess co-commentator at major events like the recent World Cup in Tbilisi .

In our preparation we came accorss the following game that Keti played one month earlier at the World Youth Chess Championships in Turkey.

 After 12. 0-0-0 the following postion arose:

Black has the bishop pair. White has a lead in development and a better pawn structure. In this position Keti played 12... a6 to prevent the white knight game coming to b5. It seems like a logical move but is actually dubious because after Nd5 white gets a structural advantage. 

To understand this, please have a look at the following grand master game.

The game shows how white can win with his strong knight and a queen side pawn majority. It is surprising that despite this being an open position, the black bishop is powerless against the white knight. The white knight has very strong outposts on both d5 and f5. White played the instructive knight manouvre Nb1-d2-f3-h4-f5.
 
It is a very instructive game that was played in Buenos Aires in 1994 at a tournament organized my Joop van Oosterom in honour of Lev Polugaevsky.  The theme of the tournament was the "Sicilian defence" in all the games. After 1.e4, black had to play c5 and white had to play 2 Nf3.  After 2...d6 or 2...e6 or 2...Nc6. White had to play 3 d4 and black had to capture and white had to take Nd4. Salov won the tournament ahead  of Anand, Ivanchuk, Judith Polgar and Karpov.
