Hey, guys, I don't understand how I didn't win this game. I have SO MANY stones of the board. I thought for sure I had it in the bag!!

Change the but to because. In Japanese rules if you play a stone inside your territory you lose a point. Pass instead.

That's literally the dumbest thing I've ever heard in my entire life.

I quit.

To give some perspective let me introduce you to yahoo answers : http://blazepress.com/2014/03/30-ridicu ... ked-yahoo/

Go is all about the efficiency of your stones. The idea is that you should lose points if you use more stones than is really necessary to defend your territory.

I get it now.

Pretty beautiful idea that.

Hahah.. one should learn the rules of the game before playing the game itself.

There are different rule sets for go. In the Chinese rules, both "territory" and the number of living stones on the board count for points at the end of the game. For those rules you do not lose a point by playing inside your own territory (unless you deprive your group of two eyes) because though you lose one point of territory you gain one point for the additional living stone. Prisoners are not counted in Chinese rules, because each of your stones that is captured in effect reduces by one the number of living stones on the board.

In Japanese rules only territory and captured stones count for points so playing unnecessarily inside your own territory loses you points.

Probably more than you will want to know about these issues can be found on Sensei's Library on this page and the links there: http://senseis.xmp.net/?RulesOfGo

You did not lose it. You won by 8.5. The score is wrong.

Still officially AGA 5d but I play so irregularly these days that I am probably only 3d or 4d over the board (but hopefully still 5d in terms of knowledge, theory and the ability to contribute).

First, let me say that this is why I say that when beginners play beginners, they should play by area scoring, such as the AGA rules use. Area scoring counts both live stones and territory. Under area rules there is no penalty for capturing dead stones. It is not always obvious if stones are dead, so how can beginners agree about life and death at the end of the game?

Second, play with your friends, of course. But if you want to advance play with SDKs or dan players. There is no point in picking up bad habits. Besides, you can learn some things from them.

Third, here are some variations. Learn the snapback.



Fourth, how can I make my claim that is dead? At that point White has 27 more points in which to try to live. How can I read that widely and deeply? The number of variations is immense. Well, I didn't read at all. A little knowledge goes a long way.



This diagram shows the minimum number of stones to make an independently living group. It takes 6 stones in the corner, 8 stones on the edge, and 10 stones in the center.

After Black is solidly alive. Even assuming that Black has no capture on the top side, Black has only one weak spot, the cut in the top left corner. Assuming that White threatens the cut and Black replies, White has only two of the stones required for life. Does that mean that Black can wait until White has played 5 stones before responding? No, because Black may have to make plays outside of the region that White uses to make life. In this case it seems like Black can only pass twice.

Now, even armed with the 6-8-10 knowledge, I would not expect a rank beginner to see that Black does not have to reply to . But later on, after for instance, it should be obvious that there is no way that any of the White stones inside the Black compound can live. There is just not enough room.

Everything with love. Stay safe.

Thinking about white's reaction put a big smile on my face.

Btw E8 captures 3 more stones.

Edit: As usual bill got there first with a more detailed and insightful analysis. Anyone would think he was some sort of expert.

You forgot to play e8
