Here comes my proposal for the 3-game-match-variant:
The Winner: The winner of the match is the player who first wins two games. Thus, the match lasts 3 games max.
Number of pieces: Each player has a total of 39 pieces for all of the 2-3 games. A headquarter will be added for each game.
Size of the board: 8x8
The mechanic:
First round: White places at least 10 pieces (plus hq) out of the 39 pieces on the board. Then black places at least 10 pieces out of his 39 pieces on the board. The number of pieces set on the board does not have to be equal. I think, this gives this variant an extra strategic edge.
Second round: Colours change, White places again at least 10 pieces on the board. Then black decides on at least ten pieces, ... see above
Third round: All remaining pieces have to be placed on the board.
A headquarter is added with each round/game.
The pieces in detail: - 4x5er - 4x4er - 4x3er - 7xrecon - 6xsab - 4x2er - 4x1er - 6xbomb plus the hq, which will be added with each round.
I guees this variant offers a whole new range for strategic thinking.
