Pawnless Chess Endgame - Examples With An Extra Minor Piece

Examples With An Extra Minor Piece

An extra minor piece on one side with a queen versus queen or rook versus rook endgame is normally a theoretical draw. An endgame with two minor pieces versus one is also drawn, except in the case of two bishops versus a knight. But a rook and two minor pieces versus a rook and one minor piece is different. In these two examples from games, the extra minor piece is enough to win.

Black to move, wins

In this position, if the bishops were on the same color, White might have a chance to exchange bishops and reach an easily-drawn position. (Exchanging rooks would also result in a draw.) Black wins:

1... Re3
2. Bd4 Re2+
3. Kc1 Nb4
4. Bg7 Rc2+
5. Kd1 Be2+
6. resigns, because 6. Ke1 Nd3 is checkmate (Speelman 1981:108–9).

Black to move, wins

In this position, if White could exchange bishops (or rooks) he would reach a drawn position. However, Black has a winning attack:

1... Rb3+
2. Kh2 Bc6
3. Rb8 Rc3
4. Rb2 Kf5
5. Bg3 Be4
6. Re2 Bg5
7. Rb2 Be4
8. Rf2 Rc1
9. resigns, (Speelman 1981:109).

Speelman gave these conclusions:

  • Rook and two bishops versus rook and bishop - thought to be a win
  • Rook, bishop, and knight versus rook and bishop - good winning chances, probably a win if the bishops are on opposite colors
  • Rook, bishop, and knight versus rook and knight - thought to be a win (Speelman 1981:170).

Famous quotes containing the words examples, extra, minor and/or piece:

    It is hardly to be believed how spiritual reflections when mixed with a little physics can hold people’s attention and give them a livelier idea of God than do the often ill-applied examples of his wrath.
    —G.C. (Georg Christoph)

    I did toy with the idea of doing a cook-book.... The recipes were to be the routine ones: how to make dry toast, instant coffee, hearts of lettuce and brownies. But as an added attraction, at no extra charge, my idea was to put a fried egg on the cover. I think a lot of people who hate literature but love fried eggs would buy it if the price was right.
    Groucho Marx (1895–1977)

    Chopin—Two embalmers at work upon a minor poet ... the scent of tuberoses ... Autumn rain.
    —H.L. (Henry Lewis)

    Whether or not his newspaper and a set of senses reduced to five are the main sources of the so-called “real life” of the so- called average man, one thing is fortunately certain: namely, that the average man himself is but a piece of fiction, a tissue of statistics.
    Vladimir Nabokov (1899–1977)
