The Philidor Position

The Lucena and Philidor positions are the most important positions to know when it comes to rook and pawn endings. Here we will be looking at the Philidor position, which allows Black to draw against an opponent that is up a pawn. It’s important to note that the Philidor position only works if the opponent’s pawn has not reached the 6th rank.


Black to move and draw

1…Rb6 This move keeps that White King off the 6th rank. [2.Rg7 Ra6 3.Rg6 Rxg6 Heading into a drawn King and pawn endgame. 4.Kxg6 Ke7 ] The Black rook heads to the first rank, to begin checking the White King. With the White pawn having been pushed, White does not have any cover from the upcoming Black rook checks.

Five Preliminary Endgame Rules

1. Before even beginning to think of making a passed pawn, put all your pieces into as good positions as possible.

Queen – Center of board

Rooks – seventh rank for White, second rank for Black. But if the enemy has two or more minor pieces the rook must be careful about leaving his own camp and must be content with commanding the open file.

Knights – Square in the center or in the enemy camp, supported by a pawn which is cannot be attacked by a pawn.

Bishops – Center diagonals; pawn support is not essential but desirable.

King – Central, provided that he is not dangerously exposed.  If the enemy has a rook, the King is best posted at or adjacent to e2(e7) or d2(d7) – fairly near the center, but still preventing the enemy rook from seizing the second (seventh) or first (eight) rank. 

2. Avoid pawn-moves while you are getting your pieces well positioned because pawn-moves create lasting weaknesses and thus make your task harder.

3. Try to free your position from weaknesses; and if possible, make it hard for the opponent to do likewise.

4. When trying to win, keep pawns on both wings. When trying to draw, play to eliminate all the pawns on one wing. With pawns on one wing only, a pawn plus is usually insufficient for a win.

5. If you are a pawn up or more, exchange pieces (not pawns) wherever you can do so without losing in position.

Exception: do not rush an exchange that will leave you with a single bishop running on the opposite color to the enemy’s single bishop. Also, refrain from exchanging if it will give your opponent two bishops against bishop and knight.

Training Position #1

White wins this position by creating a passed pawn on the Kingside.

 

Note that if the Black pawn would be on d3 instead of c3, the game would be a theoretical draw.

Copy the FEN position 4k3/1pp2ppp/p1p5/8/4P3/8/PPP2PPP/4K3 w – - 0 0 and play this position against an engine.

NOTE: There was an issue with the original post. There was a missing White pawn on d4. The diagram and the FEN diagram have been updated.

Endgame Positions

I have added a JavaScript replay chess board which contains critical endgame positions. Right now it contains three positions mainly King and pawn endgames dealing with the opposition, but I plan on adding more every couple of days.

Lucena Position

Lucena Position Silman calls the Lucena Position “The Holy Grail of Rook Endings”. In this position Regardless of who’s turn it is to move, White wins.

1.Rf2+ Forcing Black’s King to leave the scene of the battle.

1…Kg7 [1...Kg6 2.Rf4 Kg5 3.Rd4 Kf6 4.Ke8 Re1+ 5.Kf8 Rf1 6.d8Q+ Ke5+ 7.Ke7 ]

2.Rf4 Building a bridge.

2…Kg6 3.Ke7 Only now should White leave the cover of his pawn. Since promotion is threatened Black must go into checking mode.

3…Re1+ 4.Kd6 Rd1+ 5.Ke6 Re1+ 6.Kd5 Rd1+ 7.Rd4 Rxd4+ 8.Kxd4 Kf6 9.d8Q+ 1-0

King and Pawn Endings

The following game illustrates (starting in move 49.) how to exploit an extra pawn in a King and pawn endgame with many pawns left on the board. This example comes from James Howell’s excellent book ‘Essential Chess Endings’.

Things to remember:

1. Activate the king.

2. Create a passed pawn to tie down your opponent’s king.

3. Cut out any of your opponent’s counterplay.

4. Once your opponent has run out ouf pawn moves it should be easy to force his king back.

5. Either penetrate with your king and pick off your opponent’s pawns while they are busy dealing with your passed pawn or advance your king and passed pawn to paralyze your opponent’s king and force him to make concessions with his remaining pawns.

King and Pawn Endgame with Pawns on Both Wings

The following endgame example illustrates how to turn a one pawn advantage into a win:

The conversion of an extra pawn falls into three phases: 1) the King is activated. 1.Kf1

1…Ke7 2.Ke2 Kd6 3.Kd3 Kd5 2)Mobilization of the majority. 4.b4

pawns_2.jpg

Mobilize by moving the “candidate”, which is the unopposed pawn.4…Kc6 5.Kc4 h5 6.a4 h4 7.b5+ Kb6 8.Kb4 g5 9.a5+

pawns_3.jpg

9…Kb7 10.Kc5 Kc7 11.b6+ axb6+ 12.axb6+ Kb7

3) The King goes to the Kingside to gobble up the Black pawns (transformation of one advantage to another):13.Kd6 Kxb6 14.Ke7 f5 15.Kf6+-  .

Triangulation

Triangulation refers to a King maneuver which aims to lose a tempo, and leave the opponent with the move. (Dvoretsky) The d5 and d7 square are in correspondence. White in this position can easily “lose” a tempo and place his opponent in zugzwang.

Triangulation Position 1

1.Ke5! Kc6 2.Kd4 Kd7 3.Kd5 White has acheived his aim, by creating a triange with his King. We are now back to the starting position, except that White now has the opposition and it is Black’s turn to move, and the rest is a matter of technique. 3…Kc8 4.Ke6! Attaining the diagonal opposition. 4…Kd8 5.Kd6 Attaining the vertical opposition. 5…Kc8 6.Ke7 Kb8 7.Kd7 Ka8 8.c6+-

Triangulation Posiiton 2
Position after White’s 8th move.

The game would continue as follows: bxc6 9.Kc7 c5 10.b7+ Ka7 11.b8Q+.
