Linear movement

Linear movement is defined as the move of a straight unbroken line of men of the same color, one square along the line of squares they occupy, provided the square in front is vacant. It includes the move of a single man, which may be considered as a line-of-one. Linear movement does not apply to kings.

Linear movement also fuels Bushka. In the process of inventing that game I had considered it as a vehicle for movement (not for capture of course) in a draughts game. In International Draughts, differences in pace derive from one source only, namely captures, So bringing in a bit of flexibility in this strategic instrument wouldn't hurt. Apart from that it's not hard to see that it would open up a new range of tactics. The reason I didn't do so, is that Draughts is drawish, and introducing linear movement doesn't have any effect on that. Besides it's rather crammed in the opening and I could see forces grinding into interlocking positions, where the winner would be the one with the last tempo on a full board. So I abandoned the idea.
While working on
Draughts Dissected, I noticed the moves of men in Croda, a modern variant invented by Ljuban Dedic, are not restricted to the direction of capture. This is a big difference in terms of linear movement because it counteracts - if not eliminates - a tendency to grind into interlocking positions. Dameo happened quite unintentionally: it's rules fell into place in less than a minute.

Dameo

Rules

The rules mention men and kings. A king is a promoted man. If the difference doesn't matter, they may also mention pieces, for instance 'the number of pieces on the board'.

Initial position.

The diagram shows the initial position. The reason for this choice is a natural tendency of draughts games that allow straight forward movement (Turkish, HexDame, Croda), to build up forces along the sides. This initial position creates a certain balance between the center and the sides and demands an economical use of material.

  • White begins. Players move - and must move - in turn

Object

  • The object is to leave your opponent without a valid move, either by capturing all his pieces, or by blocking them completely. Draws may occur by mutual impotence or three-fold repetition of moves

Movement

  • A line of men (this includes a single man) may move one square straight or oblique forward, provided the square in front is vacant. In actual play the last man of the line one intends to move is picked up and put in front, and that's how the move is noted down. If a man ends its move on the back rank, it promotes to king. A king moves as the queen in Chess, any distance along an open line, as indicated on the right

Linear movement The king's move

In Dameo one can open with any man. On the left, the 26 unique opening moves white has at his disposal. For each of these there's a symmetric one. Black, on his first move, doesn't face a symmetric situation, so he actually has a choice of 52 answers. Thus after two moves, 1352 different positions are possible.

Capture

Capture is compulsory and has precedence over a non-capturing move. If the player to move has no capture to make, he has the following options:

  • Moving a man or a line of men
  • Moving a king

  • Although pieces may move diagonally, all captures follow horizontal and vertical (i.e. orthogonal) lines only. Men may capture forwards, backwards and sideways by the short leap. Kings may move queenwise, but they capture only rookwise, by the long leap
  • Capturing, whether by men or kings, is compulsory. If a piece makes a capture and is now in a position to effect another one, it must do so. Thus multiple captures may be made in the same turn. When a multiple capture is being made, the captured pieces are only removed at the end of the turn, and it is not allowed to jump over the same piece twice in that turn, although vacant squares may be passed over more than once
  • Majority capture takes precedence: if a player has a choice of capturing options, he must choose the option that results in the largest number of pieces being captured (kings and men counting equally). When a king has more than one option in terms of captures and destination squares, it must choose its route so that it maximizes the capturing sequence. If there is more than one way to capture the maximum number of pieces, the player is free to choose
  • If a man ends its (capturing) move on the opponent's back row, it is promoted to king. A man passing the back row in a capture, but not ending on it, does not promote

Coup Turc

Since a capturing sequence must be completed before the men are taken from the board, and since a man may not be jumped twice, Dameo allows for the "Coup Turc". Here's a bare bones example:

Coup Turc

White moves 1. c1e3 (ac5x), 2. e1c3 and the black king must capture four men, ending on d3 where he is stopped by the already captured man on c3, while d2 is still covered by the already captured man on d1.

You can play Dameo online in the ArenA.


Croda

Croda: initial position.

Included as a variant, even though the game precedes Dameo, is Croda, a draughts game invented in 1995 by Ljuban Dedic of Croatia, 1989 Checkers champion of former Yugoslavia.
Croda actually was the inspiration to invent Dameo. Many things are equal between the two - apart from an other initial position (shown above), there are ...

differences in Movement

In Croda, there's no linear movement - a man only moves on his own. And a king moves as a rook in chess: any number of unobstructed squares orthogonally.

All the other rules of Dameo equally apply to Croda.
