Key Squares & Outflanking
Position 1 / 1Mainline (17 Moves)
White leads with 1. Kd5, establishing the king on the 5th rank in front of the pawn.
Black applies Golden Rule 2 (Direct Opposition) with 1... Kd7.
White plays 2. e4! THE PAWN WAITING MOVE. Because the pawn advances WITHOUT check, Black receives no relief and is forced to yield opposition!
Black is forced to step sideways with 2... Ke7.
White plays 3. Ke5! RE-OPPOSITION. White claims opposition on e5 while keeping the e4 pawn defended, forcing Black to pick a side.
Black yields the left side with 3... Kd7.
White plays 4. Kf6! THE FLANK. Now that Black has stepped left, White outflanks right to occupy the key 6th-rank square f6! Once White lands on the 6th rank ahead of the pawn, promotion is 100% forced.
Black retreats to 4... Ke8, attempting to guard e8.
White pushes 5. e5! The pawn advances safely behind the king without check.
Black steps to 5... Kd8.
White pushes 6. e6. The pawn advances under the direct protection of the f6 king.
Black retreats to 6... Ke8.
White plays 7. e7! Pushing the pawn to rank 7 WITHOUT check forces Black's king off the promotion square!
Black is forced to yield e8 with 7... Kf7.
White plays 8. Kd7! Sealing absolute control of e8.
Black steps away with 8... Kg7.
White plays 9. e8=Q! The pawn promotes to a Queen. Victory through the Pawn Waiting Move and Outflanking!
Alternative Path Available — Consider: 3... Kf7 (Yielding to the Right) instead of 3... Kd7
Black yields to the right with 3... Kf7.
White outflanks to the left key square with 4. Kd6! White controls e7, f7, and g7.
Black is forced to retreat 4... Ke8.
White pushes 5. e7! Black's king must step to f7, allowing White's king to control e8 and promote the pawn.
