The One Thing
Connected passed pawns on the sixth rank are a decisive advantage. Advance them with king support to force promotion and deliver checkmate.

White winsConnected Passed Pawns
For sub-1000 ELO players
When you have two connected passed pawns on the 6th rank and your king supports them, you win by advancing the pawns and promoting. The defending king cannot stop both pawns. Stockfish 17 at depth 25 confirms this is a forced win in 15 moves.
The Technique
Key Moves
The moves that decide the game
What Happens With Perfect Play
Two connected pawns advance together. The defending king can block one, but not both.
Stockfish confirms the starting position is a forced win for White (+M15).
This technique works for b, c, d, e, f, and g pawns. Rook pawns (a and h files) have special drawing cases -- see the draw exceptions below.
3 Mistakes Sub-1000 Players Make
These are the patterns we see in endgames below 1000 ELO. Fix these and you will stop drawing won games.
Pushing pawns without king support
Beginners push pawns immediately without bringing the king close. The defending king captures both pawns. King support is mandatory.
Kd7If White plays e7 too early without the king on d7, Black plays Kf7 and takes both pawns. White loses the win.
Not understanding connected pawns win
Many sub-1000 players think one pawn is enough. But a single pawn can be stopped. Two connected pawns on the 6th rank are unstoppable with king support.
f7+White plays passively and Black's king catches up. The position becomes a draw. Push aggressively when you have connected passed pawns.
Promoting the wrong pawn first
White tries to promote the e-pawn when the f-pawn is blocked. Or vice versa. This wastes time and lets Black's king interfere.
f7+If White pushes e7 first (no check), Black plays Kf7 and blocks both pawns. Always push the pawn that gives check when possible.
Key Squares to Know
These are the squares that decide the game. Get your king to these squares and the pawn promotes.
e8Promotion squareThe e-pawn reaches e8 and becomes a queen. This is the turning point in the endgame.
f7Advanced pawn squareThe f-pawn on f7 restricts the Black king and forces it to make bad choices.
