Couple-swap rule2009-12-17 15:21:02
Couple-swap rule consult basic principles of Dai Xiaohan strategy rule, i.e. if couple the opponent can choice black or white.

Specifically, the opening of a game (first 5 moves), when you turn to move, you have two ways of choice, either one move of turn to color or couple moves of a black & a white. If you make one move then your opponent has to turn to another color stone. If you play couple moves, you opponent can swap color. From 6th move the Black and White will be finalize, until end the game.

The C-s rule, if a player make couple moves and tip clock regarded as end of a move. If he/her make nothing move and tip clock regarded as swap and end of a move.

The C-s rule is not reconstitute for open rules, just convert a expatiate on thought, to make it more simplified, greatly increasing the opening uncertainty.

On the opening of C-s rule, just concept of tentative first and second player, no tentative Black and White. Because the second player have also used the black stone possibility. In the RIF rule, as a respect for the opponent's etiquette, the second player (tentative White) should take a white stone to first player (tentative Black) before start of the game. In the C-s rule, that both sides should exchange two stones.

The C-s rule has nothing to do with the size of board, the tactic not same as 15 or 19 lines.

The C-s rule has nothing to do with position of first black stone, have different strategies with h8 or not.

The C-s rule has nothing to do with 26 patterns, The 26 patterns are proper subset of C-s rule.

The C-s rule every moves are valid move on full games, fully embodies the characteristics of renju have not take off the moves, (currently Yamaguchi trial rules will be N-1 invalid moves).

The C-s rule at most have two times to swap, relative fair for both player. Both sides can not independently control the start, and avoiding the drawbacks situation before the game to a home study or memorize a particular type can be set unbeaten.

The C-s rule there are two main problems to test out both players in opening stages of a game:
A) To estimate the situation - according to a limited number of moves (up to 5) to determine with an excellent black or white or balance.
B) To build a situation - generally through couple moves to balance the situation, the difficulty is more greater than the point A, in particular already two or three moves on the board. Because it is the last opportunity for the balance, build imbalances would bring the whole game passively.

The C-s rule has nothing to do with forbidden moves, have different strategies with forbidden or not (renju or gomoku).

The C-s rule will not be too spread around, and if that will be true win to black or white.

We will held C-s trial competition Dec. 26, 2009. We will be live online during the competition. live addr.:
