Queen and Pawn vs Rook and Pawn: Winning with a Queen Sacrifice
White to play and win
PlayThe same position as the drawn fortress, but now you have the move, and it wins. The rule: when the queen cannot break the fortress, give her up for the rook, but only if the pawn ending that follows is won. Here it is: your king escorts the g-pawn while his pawn is far too slow.

The theory
Watch the method: press play to see the winning idea run, or step through it move by move.
Dedrle's 1925 position is a draw with Black to move and a win with White to move, but the win looks nothing like a squeeze.
Use the move. With Black to move, his king walks to g7 and holds the draw. With you to move, you win by preparing a queen sacrifice for the rook.
The device: a queen sacrifice. Qb8 Rg6 Qb4+ Ke8 Qe4+ Re6 Qxe6+ fxe6 Kh6. Giving up the queen for the rook looks absurd and is completely winning: the resulting pawn ending is lost for Black, because the white king escorts the g-pawn while the e-pawn runs far behind.
The lesson. In queen versus rook and pawn, liquidation into a pawn ending is a standard winning tool. Check it before you settle for manoeuvring.
In this drill the win is exact. Do not spend the tempo on an idle check.
