9...c4!
Black sets out his stall for the impending ...b5-b4 lunge. The c-pawn bypasses the white centre and instead is used as a spearhead for the upcoming pawn storm. This plan is remarkably difficult to counter, as any Nxb5 would just open the b-file for the black rook on a8 to come to b8. If the b-pawn is not captured, then ...b4 and ...c3 is likely to open up White's defensive pawn structure in any case. On the other side of the board, g4 and f5 ideas don't quite hit the spot, as Black has many defensive pieces which cover any f5-f6 pawn advance. See how the game continuation demonstrates this in practice.
10.f5 b5 11.fxe6
11.f6 gxf6 looks more dangerous for Black than it really is. White cannot take advantage of the open g-file, and also the queen on d2 is too far away to do any damage. After 12.Bh6 fxe5 13.Bxf8 Bxf8 Black enjoys great compensation for the exchange, with two pawns and the upcoming pawn storm on the queenside.

This bishop must be kept for attacking and defensive purposes.

Now Black has two options: to capture the pawn or to sidestep and leave it on h7.

23.h6 g6 doesn't change much.

πΉ George Koltanowski
πΉ American-Belgian chess player
π° George Koltanowski was a Belgian-born American chess player, promoter, and writer. He was informally known as "Kolty".
π Country: Belgium
π United States
π Born: 17 September 1903, Antwerp, Belgium
π Died: February 5, 2000, San Francisco, California, United States
π Title: International Master (1950)
Grandmaster (honorary, 1988)
π Books: Adventures of a chess master, Colle System ...
π° Koltanowski set the world's blindfold record on 20 September 1937, in Edinburgh, by playing 34 chess games simultaneously while blindfolded, making headline news around the world. He also set a record in 1960 for playing 56 consecutive blindfold games at ten seconds per move.
Born into a Polish Jewish family in Antwerp, Belgium, Koltanowski learned chess by watching his father and brother play. He took up the game seriously at the age of 14, and became the top Belgian player when Edgar Colle died in 1932.He got his first big break in chess at age 21, when he visited an international tournament in Meran, planning to play in one of the reserve sections. The organizers were apparently confused or mixed up about his identity and asked him to play in the grandmaster section, to replace an invited player who had not shown up. Koltanowski gladly accepted and finished near the bottom, but drew with Grandmaster Tarrasch and gained valuable experience. He thereafter played in at least 25 international tournaments. He was Belgian Chess Champion in 1923, 1927, 1930, and 1936. However, Koltanowski became better known for touring and giving simultaneous exhibitions and blindfold displays.
