Queen vs. Pawn on 7th

Queen against pawn on the seventh is a lone queen stopping a pawn one step from promotion. It beats a centre or knight's pawn. A rook's or bishop's pawn draws if the stronger side's king is far away.

Start0/1
The pawn on a2 shelters the king on a1. Qc2 covers b1 and b2, and Black has no legal move: stalemate. With the white king this far away, a rook's pawn draws.

Against a centre or knight's pawn, the queen checks until the king must stand in front of its pawn, then uses the free move to bring its own king closer. Against a rook's or bishop's pawn, stalemate breaks that method.

How to do it

  1. 1Check until the defending king has to step in front of its pawn.
  2. 2Use that free move to bring your king one square closer.
  3. 3Repeat until your king is close enough to win the pawn or mate.

Questions
Why do rook and bishop pawns draw against a queen?
Stalemate. With a pawn on a2 the king sits on a1 and has no moves once the queen closes in. With a pawn on c2 the king goes to a1, and taking the pawn leaves it stalemated.
When does a queen beat a rook's pawn on the seventh?
When the queen's own king is close enough to help mate before stalemate matters. How close depends on the exact position, so check a tablebase rather than a rule of thumb.
