17.Na2!
QUESTION: What is the logic behind this knight retreat? ANSWER: By moving the knight to a2, White has three objectives. The first is to prevent any possible rook sacrifices on the c3-knight. Secondly, White clears the third rank for defensive purposes by the queen and later a rook on h3. Thirdly, the move also discourages Black from advancing 17...b4 as after 18 axb4 Nxb4 19 Nxb4 Bxb4 the exchange of knights nips any possible black attack in the bud.

The rook lift tells Black's king that even on the queenside, he will not be safe as the rook can now swing to b3 or c3.

The knight on h5 proves to be a big stumbling block as far as a kingside attack is concerned. 15 g4 would allow the knight to plonk itself on f4 as White is rarely advised to swap off his good bishop for it even if it means winning a pawn. Indeed the pawn in question here would be Black's e-pawn whose presence is currently hindering the King's Indian bishop. Trading off his good bishop for this piece with a Bh6 makes little sense for White anyhow as Black could defend any unlikely attack along the 2nd rank by advancing his f-pawn and using his queen. --- Andy offers the best plan. It isn't so risky advancing the pawns around the white king as Black has no way of exploiting this. His pieces are unable to enter the white position on the kingside and the following encounter demonstrates how White is able to utilize his space advantage:

π #about_Tarrasch
πΉ Siegbert Tarrasch
πΉ Prussian Chess master
π° Siegbert Tarrasch was one of the strongest chess players and most influential chess teachers of the late 19th and early 20th century. Tarrasch was born in Breslau, Prussian Silesia.
π Full name: Siegbert Tarrasch
π Country: Germany
π Born: 5 March 1862
Breslau, Province of Silesia, Kingdom of Prussia
(now WrocΕaw, Poland)
π Died: 17 February 1934 (aged 71)
Munich, Germany
π° Tarrasch was born in Breslau (WrocΕaw), Prussian Silesia. Having finished school in 1880, he left Breslau to study medicine in Halle. With his family, he settled in Nuremberg, Bavaria, and later in Munich, setting up a successful medical practice. He had five children. Tarrasch was Jewish, converted to Christianity in 1909, and was a patriotic German who lost a son in World War I, yet he faced antisemitism in the early stages of Nazism.
π°Tarrasch was a very influential chess writer, and was called Praeceptor Germaniae, meaning "Teacher of Germany." He was editor of the magazine Deutsche Schachzeitung in 1897 and wrote several books, including Die moderne Schachpartie and Three hundred chess games. Although his teachings became famous throughout the chess world, until recently his books had not been translated into English.
π° He took some of Wilhelm Steinitz's ideas (e.g. control of the center, bishop pair, space advantage) and made them more accessible to the average chess player. In other areas he departed from Steinitz. He emphasized piece mobility much more than Steinitz did, and disliked cramped positions, saying that they "had the germ of defeat."
