uranther cannot avoid massive losses. Even with optimal play, he will be 40 or more points behind after the situation on top settles. If I were playing Black, I would do the following:

After this, I would make a last ditch effort to save the Black group on the bottom. If unsuccessful, I would then say "makemashita."

Edit:
Actually, after the following diagram, White still threatens to play "a" and then "b," so Black does not even get sente ... Though spot for Black.

I assume that you went to the Mercury Cafe to play go in Denver?

I can say that my favorite place to play go is Pablo's Coffee on 6th Avenue and Washington St. There are a several people who regularly play there most of whom are around 1kyu or 1dan and catercorner is a Korean/Japanese restaurant with a friend of mine who would often be up for a game.

Awesome, thanks for the info! I'm not sure where uranther plays, but I now have one more place to got to when I visit Denver. :)

Looks like I have to push and cut so I don't get sealed off (as bad). I still need to go back and make some eyes in the top right group. White's top group seems to be okay on eyes.


Dragon Pie: Yep. Pablo's Coffee sounds cool - I will check it out sometime.

For some reason, :w35: makes me remember some stupid cell phone commercial where they say "Disconnected!" in a really loud and obnoxious tone of voice. That random observation aside, it is too late for Black's group to run to the center. :-|

There's not much to add here. At least half of Black's group dies. I think it is possible for uranther to get sente after he saves a part of his group, but he'll be too far behind on points to have any hope of winning--unless, of course, he manages to somehow save his stones on the bottom, which I don't think he can do.

If White were to play :w2: as in the diagram (White should play at "a," instead, which kills half the group), Black group gets a second eye and lives.

Instead of :w41:. I could have also played the following, but that gives Black a huge ko threat (at "b" or "c"):

Of course, there are no ko fights anywhere in sight, so giving Black an additional ko threat would not matter. Still, why do it when it is not necessary?

I resign. This upper right group is dead. It can only make one eye and a false eye... Good game Intrepid!

Thank you for the game. I'll post an sgf file with the game in a week or so. Also, I'll ask a 5 dan friend to offer comments on the moves.

The biggest mistake from me was definitely move :wc:. I thought I found a clever way to kill the Black group because it let me play :w4: (in the following sequence) at J3 rather than at "a" while also granting me all the other benefits.

As you'll see in one of the latter comments, however, you had a way of saving your group after :wc:.

Otherwise, I am generally satisfied with my play. Then again, I have not yet read other people's comments, so that feeling may yet change. :)
