I started playing Go recently and I am fairly new to the game. Please excuse me if this is the wrong forum section.
I played this game: gugulete vs. myonov
I am wondering why territory A2 is not scored for white and G9 for black as they are fully encircled?
Is it because A3 and H9 are kind of weak and could possibly be captured?
Is there a difference if Chinese rules were applied for these exact intersections - A2 and G9?
Is there an easy way to distinguish if the position is completed and does the different rules - Japanese/Chinese have different completion requirements?
I guess on a real board, after two passes I as white, could argue that I could possibly capture H9 and thus to save it my opponent needs to play G9 and thus it is not part of a territory. Is it that how it works or we need to actually execute the moves in order to score it?
Follow the borders of your groups and see if there some piece of the border that is not fully secured yet. You will get the hang of it when you have played some more games.
And if you pass prematurely, the OGS system displays a notification in your screen, saying this and/or that point should be played first before the game will go to the counting phase.
One more common difference, is that in the general case, filling dame doesn’t matter in territory scoring, but you need to leave an even number of dame before passing in area scoring. Most differences in the implications of different rulesets are either exceedingly infrequent (such as triple ko under Japanese Rules versus under superko), or this sort of very easy adjustment to make
Until you get to be an advanced go player, all rulesets are pretty equivalent and you don’t have to bother yourself with understanding their differences.
What matters is to understand when the game is finished which you can consider as being the same under different rules. Simply close well the borders, don’t leave any doubt or weakness like stone(s) with only one liberty that could be captured and you may even play what we call the dame (from Japanese), the last neutral (=won’t make a difference when scoring) points between the black and white stones.
