# Endgame studies with annotations from world champions. Emmanuel Lasker

Compiled by Gia Nadareishvili, Grandmaster for chess compositions (1921-1991). Presented as puzzles (see move lists for variants and annotations).

Alexey Troitsky. White to play and draw.

An ingenious idea. White try to Queen their pawn with check. Due to this, the Black King, despite a very open board, is very cramped in its movements, and White manage to give perpetual check with their Knight.

Alexey Troitsky. White to play and win.

The motive, based on purely geometrical ideas, is to limit the movement of the Rook by the Bishop and vice versa. This can be achieved, for instance, by occupying the squares attacked by both Bishop and Rook.

The Bishop can hold the f-pawn from a3, and the Rook can hold the b-pawn from the b-file. Or, alternatively, the Bishop can hold the b-pawn from f4, and the Rook can hold the f-pawn from the f-file. It's up to Black to choose. To ruin the coordination of the Black pieces, White deflect the Black Rook from the 5th file with a Knight maneuver.

Leonid Kubbel. White to play and win.
The author's idea was to present the geometrical motive of struggle of two opposing Queens, both on straight lines and diagonals. Of course, the author strives to do most things with minimal material and make the endgame study look like a real practical endgame.
Leonid Kubbel. White to play and draw.
The idea here is stalemate. All White pieces' strength are used very subtly. First of all, they need to force Black to capture the Knight at the 1st file.
Henri Rinck. White to play and win.
The material is scarce, but the endgame study has a number of motives with the passed pawn. The latter is guarded by the Bishop from the Rook's attack, even though the Rook is severely hampered with the f6 pawn.
The Bishop manages to lock down the g-file for the Rook.

@NimzoRoy: Leonid Kubbel was a legend of Russian/Soviet chess composition. His brothers also played chess: Arvid Kubbel participated in three USSR Championships, and Evgeny Kubbel was a fantasy chess composer.

GOOD PUZZLES! Of course maybe I liked them because I solved all of them pretty quickly, albeit with a fair amt of guesswork...I'm not familiar with Kubbel, but offhand he seems to be in the same league with Rinck and Troitsky

1. Bg5 Rg1, and it's impossible to save the g6 pawn: 2. g7 Rxg5, then Black easily exchanges their Rook for b-pawn and wins. 2. Bxf6 Rxg6, and Black at least draws because White can't prevent Black to exchange the Rook for the b-pawn.
