Each side of the board has a single corner, with one dark square, and a double corner, with two dark squares. The double corner sits nearest each player's right side.
What is the double corner in checkers?
Quick answer: The double corner is the corner near each player's right hand where two dark squares meet, giving a defending piece two escape squares and making it the strongest corner for holding a draw.
Understanding the double corner is a key step from beginner to intermediate play, because so many endgames are decided there.
Two corners, two roles
Why it matters
A piece defending in the double corner has two squares to retreat to, so it is much harder to trap there. Skilled defenders steer weaker forces toward the double corner to save a draw, while attackers try to force the enemy into the vulnerable single corner.
