One of the most famous endgame positions in chess, the starting point of the Saavedra position is as follows: white has his king on b6 and a pawn on c6, while black's king is on a1 and rook on d5:

Despite its apparent simplicity, it is a position of extraordinary subtlety with devious traps hidden at every tu rn. Observe how white, to play, wins:

1. c7
The only move to win.
1. ... Rd6+
Black cannot threaten the pawn, so he can only give check to retard white's progress.
2. Kb5
Again, this is forced; if Kb7 then black draws with the pin Rd7, while after Kc5 black will play Rd1 threatening the skewer Rc1+.
2. ... Rd5+
3. Kb4 Rd4+
4. Kb3 Rd3+
The black rook chases the king as far as possible down the b file; b2 is off limits because of the black king on a1, so now white must pl ay:
5. Kc2
It is now safe for white's king to move to the c file, si nce the rook can no longer get to c1 without being captured.
5. ... Rd4!
Black's cunning knows no limits! Now if white plays c8=Q then the fork Rc4+ forces white to capture the rook with his queen, thus stalemating the black king and drawing the game. White, however, wins w ith an underpromotion:
6. c8=R!
Now after Rc4+ white can simply capture the rook and proceed to checkmate black.
6. ... Ra4
The only move, otherwise white can checkmate with Ra8.
7. Kb3 1-0
With his final move, white threatens both to capture the r ook and to checkmate with Rc1. Black cannot meet both threats, so resigns.
