It’s the last match of the season and you’re facing your rivals for the league championship.

If you win, you win the league, if you draw there will be a play-off, and if you lose, they will win. The good news is that you have the white pieces.

Yours is the last game to finish. The match is level, you’re playing on increments, with a large crowd gathered round your board.

Deep into the ending, here’s your position, with White to move.

How will you continue? Can you find a way to win? Naturally, a player with your endgame skill will be supremely confident about winning a potential Q v R ending, even at 10 seconds a move.
