I have one more question: At black 211, which is the bigger move (As in points)? Take the ko and let white capture two stones or save my two stones and possibly have white fill. Also I could've extended to atari white after I took the ko, but I didn't notice. orz
You are very welcome, Abyssinica.
Let me preface this by saying I am by no means an endgame expert - it is the weakest part of my game. There are all sorts of rules for point values based on what is sente, what follow-ups you have, etc and I have no idea how most of those work. I mostly study the opening, which is why I know about that vital point in the Low Chinese.
You note that you needed to extend. That would have made your move larger for sure. But as it was played, those moves look about the same to me. Maybe black's was better by a point or so.
Taking one white stone and saving one black stone is basically the same as saving two black stones points wise. However, your move could have actually been bigger even without the push because it was sente for black.
No doubt you should extend to remove two more points in sente with that push. (I'm sorry to see that this was the difference in the game...) But even as it was played you got to fill the ko in sente, take Q6 in sente, and then take another endgame point. Overall, I think locally black came out ahead in that sequence while keeping the initiative. Not ahead by a lot, but a bit.
Also, at move 227 you should play H15 for yourself. That would also remove a point for white. In general don't fill those first line ko-type moves until the end of the game (unless you read a reason the move is needed). They are basically dame points. But even then, it would still be a half-point win by white.
Had black extended first though... well...
R6 is better. Notice
R11 is farther away than
K4.
