Poddavki

Poddavki (, "giveaway") is a draughts (checkers) game based on the rules of Russian draughts, with the variation that a player wins if they have no legal moves on their turn, either by giving up all their pieces or having them all blocked. As in most varieties of draughts, capturing is mandatory. The game is played in Russia and some parts of the former Soviet Union.
Notation.
Games and positions are recorded using a special notation – algebraic notation. The vertical columns of squares are labeled from a to h. The horizontal rows of squares are numbered 1 to 8 starting from White's side of the board. Thus each square of the board has a unique identification of file letter followed by rank number.
