Philidor's Position

Philidor's position can refer to two positions: One with Q + K vs. R + K and R + P + K vs. R + K. We will be looking at the rook endgame.

Black to move

A possible position of Philidor's position. This is a draw for white.
The strategy that white undertakes to draw works with flank pawns too.

Why is this a draw? Let us take a look. The black king is totally cut-off by the white rook, and an exchange of rooks leads to a draw due to white having the opposition.

The only chance is to push the pawn. Let us look at this.

1...e3

2.Ra8! Without the pawn on e3, Ra8 loses because 2...Ke3 threatens mate and forces the king to move. The lucena position will then be reached and it is a win for black.

2...Kf3

3.Rf8+ The continuous checks from the back forces a draw.

1/2 - 1/2
