6 | At the very first move of the game, white make only one move - as usual. | |
7 | However, after that and for all the game, each side must play as many moves | |
8 | as the opponent just played plus one. | |

11 | If a move gives check, then the sequence stops here, but the opponent can | |
12 | still play as many moves as would be theoretically possible. | |
13 | Also, if a checkmate or stalemate situation occurs before the maximal number | |
14 | of moves are played, the game ends. | |
15 | There are no en-passant captures. | |
