A classical masterpiece

In the October issue of the Deutsche Schachzeitung in 1888 the following position was published, which later became one of the most well-known studies of all time. It features several queen sacrifices followed by skewers.

The key position in his study is a mutual zugzwang, so I have tried to compose a version with a thematic try.

The immediate 1. Qb4? is answered by the waiting move 1... Qc2! (and not 1... Qc6? 2. Ka8 zz +-), and after 2. Ka8 Qc6, white is in zugzwang.

The solution is 1. Ka8! Qc6 (forced), and only now 2. Qb4! zz etc.

mutual zugzwang

Other versions were also composed since 1888, the best is probably Zhukov's where four units move before the key position:

The original version was one move shorter:


White wins

An improved version was published in the e-book "In Search of Beauty" (2025) by "Paparazzi", who added the try 1.Ng4? and the surprising first move 1.Nf5! to the study. He moved the black king away from the a-pawn, not to "strangle" the white king. Visually, this initial position seems lighter, and all black pieces are on white squares (and the white ones on black squares). On the other hand, that pawn is hanging in the initial position, which I usually try to avoid.

White wins
