How to Win 2 Kings vs 1 King in Checkers

Quick Answer: Why the Lone King Runs to the Double Corner

One of the most frustrating moments for beginner and intermediate checkers players happens when you outplay your opponent all game, reach a 2 Kings vs 1 King endgame, and then watch helplessly as their last King bounces back and forth in the cornerforever.

In standard 8×8 American Checkers / English Draughts, a lone defender King will never voluntarily run to the Single Corner (square 4 or square 29), because a single corner has only one exit diagonal and is easily sealed off. Instead, every smart opponent (and every AI bot) immediately retreats into the Double Corner:

• Top-Left Double Corner: Squares 1 and 5
• Bottom-Right Double Corner: Squares 28 and 32

Because squares 1 and 5 connect on a mini-diagonal at the edge of the board, a single King cannot force the defender out. You must bring both of your Kings together and threaten a forced 1-for-1 trade (or 2-for-1 fork) so that mandatory jumping forces the enemy King out of its shelter.

Step-by-Step: The 5-Move Double Corner Expulsion (Squares 1 & 5)

Suppose your opponent's lone Black King is hiding on square 1 (and shuffling to 5), while you control two Red Kings. First, march your two Kings to squares 10 and 14 with Red to move.

From Red Kings on 10, 14 vs. Black King on 1, execute this exact 5-move sequence:

1. 1. 14-9! — You step toward the edge, threatening to move into square 5. Black has only one legal move on the entire board: 1... 1-5.
2. 2. 10-6! — Your second King steps into square 6, right next to Black's King on 5. Why can't Black jump you? Because square 1 behind you is blocked or on the edge! Black is forced back into the corner: 2... 5-1.
3. 3. 9-14! (or 6-2) — The waiting/preparation move! By stepping your King from 9 back to 14 (controlling the 9–14 diagonal while keeping your other King on 6), Black is once again left with only one legal move: 3... 1-5.
4. 4. 6-1!! — The decisive invasion! Your King steps right into square 1 behind Black's King on 5. Now Black on 5 cannot return to 1, so Black is legally forced out of the double corner: 4... 5-9.
5. 5. 14-5 (1-0) — Your waiting King on 14 jumps over 9 to 5, capturing Black's last piece and winning the game on the spot!

Note for the Bottom-Right Double Corner (Squares 28 & 32): By 180-degree board symmetry, if the lone King hides on 32 and 28, place your two Kings on 19 and 23 and play the exact mirror sequence: 1. 19-24 32-28 2. 23-27 28-32 3. 24-19 32-28 4. 27-32! 28-24 5. 19-28 (1-0).

What If the Lone King Runs to the Single Corner? (Payne's 1756 Trap)

If your opponent flees toward the Single Corner (square 4 or square 29) or gets driven along the side of the board, winning is even faster. In 1756, English mathematician William Payne published the classic 3-move Single Corner trap:

• Starting Position: Red Kings on 15 and 16; Black King on 4 (Red to move).
• 1. 16-12! — Cuts off the side escape square 8. Black must play 1... 4-8.
• 2. 15-11! — Steps alongside square 8 while protected. Black must retreat 2... 8-4.
• 3. 12-8 (1-0) — Seals Black's King on square 4 with zero legal moves (or forces an immediate fatal jump).

Level Up: First Position & Second Position (Sturges, 1800)

Once you master 2 Kings vs 1 King, the next milestone toward master-level endgame play is learning First Position and Second Position from Joshua Sturges' 1800 treatise:

What About Flying King Variants (Russian Shashki & Brazilian Damas)?

Be careful! The 2 Kings vs 1 King win above applies specifically to 1-step King rulesets like American Checkers. In Russian Checkers (Shashki) and Brazilian Damas 8×8, where Kings fly across the entire diagonal, 2 Flying Kings vs 1 Flying King on an open board is generally a theoretical draw unless the lone King is already trapped on the first move—instead, you need 3 Flying Kings vs 1 Flying King (the "Triangle / Треугольник Петрова" method) to force a win!
