Won King and Pawn ending out of the opening

jgonz, playing at the Internet Chess Club with the White pieces out of the country of Mexico. elected to exchange pieces every chance he got in this French Defense. He was so eager to swap pieces that he willingly allowed Black a four to three pawn majority on the King side.

It is well known that White can do something similar in the Ruy Lopez exchange variation  securing a 4-3 King side majority at the expense of conceding the Bishop pair. In praxis Aaron Nimzovitch, White rarely wins because of said majority.

In the position you see, White's Knight and Rook, at first glance. appear to be on threatening squares. However, they are unable to combine around the Black Monarch and Black's simple plan becomes to at least trade off Rooks with the fantasy of also exchanging Knights leading to won king and pawn ending.

The winning Black pawn structure owes its soul to the fact that White's 4-3 Queen side majority can never bear the fruit  of a passed pawn since the c pawns are doubled at c2 and c3. Such a Queen side majority is frequently called unhealthy by folks at the Mechanics Chess club in San Francisco and the rock and roll one there frequented by New Mexico chess legend Jess Kraai who authored Lisa, a chess novel which had a refreshingly puerile point of view and was worth reading.

Forcing a trade of Rooks is usually easier that coercing swap of Horses, but many endgame books point out that Knight and Pawn endings share many of the characteristics of pure King and Pawn endings, so getting the Towers off the board is a good start in Black's quest to secure the full point!
