Win by giving the pawn back

From Chess Fundamentals by José Raúl Capablanca (1921), Chapter 1 — First Principles, Example 8 (Pawn Endings) · Intermediate · about 6 minutes.

The hardest of Capablanca's 'simple' endings, and his favourite kind of lesson: two pawns against one where the direct pushes only draw, and the winning method runs through a sacrifice. White's pawns will charge deep — and then White gives one back on purpose, because the real prize is Black's pawn and the squares behind it. Capablanca offered this ending as proof that even near-empty boards hold enormous difficulty, and that mastering these elements is what mastery is.

The line

• 1. Ke4 — Neither immediate push wins: 1.f5 g6! and 1.g5 g6! both hold (opposition again — it governs every pawn ending). The king leads.
• 1... Ke6
• 2. f5+ — Space, with tempo.
• 2... Kf6
• 3. Kf4
• 3... g6 — Black stakes a claim. Had this pawn stayed home, we'd transpose into the breakthrough lesson.
• 4. g5+
• 4... Kf7
• 5. f6 — The pawns bite deep — but they cannot promote by themselves. Try to force f8 from here; you'll find Black always holds it. So White changes plans entirely.
• 5... Ke6
• 6. Ke4 — Back goes the king — to come around from the other side.
• 6... Kf7
• 7. Ke5
• 7... Kf8
• 8. f7 — The star move: White GIVES the pawn away. Black must take it — and in exchange White's king wins g6 and, with it, the game.
• 8... Kxf7
• 9. Kd6 — The outflanking begins. Material is still even after the coming capture, but the king's position is decisive.
• 9... Kf8
• 10. Ke6
• 10... Kg7
• 11. Ke7 — Every step forward takes another square Black needs.
• 11... Kg8
• 12. Kf6
• 12... Kh7
• 13. Kf7 — Now the g6-pawn is lost by force.
• 13... Kh8
• 14. Kxg6 — Even material — and a textbook won position: king in front of the pawn, the previous lessons in action.
• 14... Kg8
• 15. Kh6 — The only winning path: the king clears the way to h7 before the pawn moves. Capablanca notes this is the ONLY way — experiment and see.
• 15... Kh8
• 16. g6 — Only now the pawn.
• 16... Kg8
• 17. g7 — No check — that's the point. Black must step aside.
• 17... Kf7
• 18. Kh7 — The king guards g8, and the pawn queens next move. A sacrifice, an outflanking, and two earlier lessons stitched together — from a position with four pawns on the board.

Takeaway

When pushing can't break the blockade, look for the move that trades your advantage for a better one: here a pawn for decisive king position. And notice how the ending resolved into patterns you already know — that's why the elementary endings come first.
