Russian Checkers (Shashki): Complete Rules, Flying Kings, Tactics & AI Solver

Among the global family of draughts games, Russian Checkers (known natively as Русские шашки or simply Shashki) stands out as one of the most explosive, dynamic, and tactically electrifying board games ever conceived. While it uses the exact same 8×8 board and 12-versus-12 starting array as English/American Checkers, the rules governing movement and captures create a fundamentally different game.

In this guide, we explore the official rules certified by the International Draughts Federation (IDF), examine key tactical principles like the Great Diagonal, and demonstrate how you can calculate optimal moves in Russian Checkers using our free Russian Checkers Solver & AI Calculator (Русские Шашки).

1. What is Russian Checkers (Shashki)?

Played throughout Eastern Europe, Central Asia, the Baltic states, and international draughts federations worldwide, Russian Checkers has a storied heritage spanning centuries. In the late 19th and early 20th centuries, Russian masters codified tournament rules under the auspices of unified chess and draughts federations.

Unlike English Checkers—where pieces crawl forward one square at a time and kings only move one square—Russian Checkers turns kings into high-velocity long-range pieces and allows ordinary men to jump backward. The result is a game with far fewer draws, violent tactical sacrifices, and lightning-fast tactical strikes.

2. Russian vs. American vs. International Draughts

Here is a breakdown of how Russian Checkers compares to the other two major variants played globally:

3. Flying Kings (Дамка): Infinite Diagonal Range

In Russian draughts, a piece that reaches the opponent's back rank becomes a Flying King (in Russian, Дамка, pronounced "damka"):

If another enemy piece can be captured from that landing square (by turning 90 degrees onto an intersecting diagonal), the King must continue jumping. Because a King can control up to 13 squares simultaneously on an 8×8 board, promoting even a single pawn to a King is almost always decisive in tournament play.

4. Backward Captures for Ordinary Men

One of the biggest surprises for American checkers players is that ordinary pawns can jump backward. While a man can only step forward during non-capturing moves, if an enemy piece is positioned immediately behind it with an empty square beyond, the man is strictly required to jump backward to capture it!

This single rule changes positional strategy completely: you can never safely park a checker behind an enemy piece thinking it is invulnerable. Flank attacks and infiltration requires intense tactical vigilance.

5. Promotion on the Fly (Mid-Jump Crowning)

Perhaps the most unique and elegant rule in Russian Checkers is mid-jump promotion (known in Russian literature as с превращением на лету):

• If an ordinary man enters the enemy king row during a multi-jump sequence, it immediately transforms into a Flying King.
• If there are further enemy pieces that can be jumped from that back-rank square according to King rules (such as flying backwards along an open diagonal), the newly crowned King must continue capturing as a King on that exact same turn!
• Contrast this with American Checkers, where a piece that reaches the crowning square must immediately stop and end its turn.

6. Essential Tactics: The Great Diagonal & Petrov Triangle

Mastering Shashki requires learning the fundamental geometric corridors of the 8×8 board:

The Great Diagonal (Большая дорога)

The long diagonal connecting the corner squares (spanning 8 consecutive dark squares, from $a1$ to $h8$ in algebraic notation) is known as the Great Diagonal (*Большая дорога*). A Flying King that occupies the Great Diagonal divides the opponent's forces in half and can never be dislodged without a multi-piece sacrifice. Whoever controls the Great Diagonal usually controls the endgame.

The Petrov Triangle (Треугольник Петрова)

Invented and analyzed by the 19th-century master Alexander Petrov, the Petrov Triangle is an endgame technique allowing three Flying Kings to systematically trap and defeat a lone enemy King even when that lone King controls the Great Diagonal. It is considered required reading for any serious draughts competitor.
