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.

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).

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).

“To know how to suggest is the great art of teaching. To attain it we must be able to guess what will interest; we must learn to read the childish soul as we might a piece of music. Then, by simply changing the key, we keep up the attraction and vary the song.”
