2...Rxa3+ 3.Kb2 Ra2+
3...Rb3+? 4.Ka2 followed by f8Q+.

Book: My System (Quality Chess Edition)
"Few masters, if any, have loved the game of chess as Nimzowitsch did".
Grandmaster Gideon Ståhlberg about Grandmaster Aron Nimzowitsch.
My System, edition published by Quality Chess:
"The problem for an English-speaking audience has been that My System was written in German more than eighty years ago. The commonly-used contemporary translations have sounded dated for some time, and were always questionable: the translators frequently toned down many passages, fearing Nimzowitsch’s biting wit would be too controversial.
This edition uses a brand-new translation that recreates the author’s original intentions. For the first time an English-speaking audience can appreciate the true nature of a famous chess book" (Quality Chess).
Wikipedia about My System:
"My System (German: Mein System) is a book on chess theory written by Aron Nimzowitsch. Originally over a series of five brochures from 1925 to 1927, the book — one of the early works on hypermodernism — introduced many new concepts to followers of the modern school of thought. It is generally considered to be one of the most important chess books of all time".

White didn't find the best move in the position
above.
The game continued with 30.Rf7+? Kh6 and
ended later with a draw.
Black would have been in big trouble if white had
found the best continuation.

Endgame study (2)
An endgame study from 1979 by Mario Matous.
White to move and win.
Solution:
1.Kf2!
White has only draw after 1.Qxf1+? Kh2 (2.Qf2+ Bg2 3.Qh4+ Kg1 4.Qf2+ Kh2 5.Qf4+ Kg1).
Black has the advantage after 1.Qh4+? Nh2.
And don't fall for 1.Kxf1?? La6.
1...Bg2
A better try for black than 1...Nh2 2.Bf3+ and 1...Qa6 2.Bf3+! with both more easy winning for white.
2.Bf3 Qg7 3.Qh4+!
Black has draw after 3.Qxf1+ Kh2 4.Qg1+ Kh3 5.Bxg2+ Kh4 6.Qh2+ Kg5.
3...Nh2 4.Qh8!!
Stops black from playing 4...Qb2+. And 4...Qxh8?? 5.Bxg2+ is mate.
4...Qg6 5.Qh7! Qg5 6.Qh6! Qg8
The black Queen is forced to g8, where it soon will be captured by the white queen.
7.Qc1+ Nf1 8.Qxf1+ Kh2 9.Qg1+ Kh3 10.Bxg2+ Kh4 11.Qh2+ Kg5 12.Qg3+ followed by Qxg8 winning the black queen.
