the go seigen game ikeda mentioned might be nice
- Rule of scoring: A player's score is the number of that player's played stones plus the number of grid points in that player's territory. If the first pass was made by White, however, then 1/2 point is subtracted from Black's score and added to White's score. The winner is determined by comparing the players' scores.
The following points may help with application of the rule:
- Ikeda's Rule refers to the very first pass of the game. (In most cases the very first pass of the game will occur as one of the two passes that precede the agreement phase. Yet should someone pass earlier it this earliest pass is refered to by Ikeda. See Pass Fights for more.)
- normal territory komi should be used when Ikeda's Rule is used as White will be compensated for the one point more-value of black's first play if White passed first. (Commonly this denotes either a misjudgement of White or that Black got the last valuable(aka competetive) board play and thus had one more move than White over the whole game.)
- this rule remedies the 'free mending in case of even dame' phenomenon and thus presents opportunity for more interesting play by punishing unecessary reinforcement of one's territory in the presence of an even amount of neutral points.
