Migeru v. rg game 2 (moves 1-10)  

W1: I'll give you two stones this time. -- Migeru

B4: I thought you might play there. Are Jerome and I about the same level do you think?

W5: dunno.

Anonymous: Remember the proverb "If you don't know ladder, don't play go." Hint: I'm referring to B8.

Migeru: Hint: rg is about 30k. (I've added the ladder below)

B8: Ouch! -- rg

W9: The thing about handicap games is waiting for black to make two mistakes in a row, like B6 B8 here. Let's make this a life and death problem (see the bottom of the page) -- Migeru

B10: I think I will need a handicap of 4/5 against you in order to stand a chance, I also need a book on life and death situations. I also need to paint 17 walls.

Migeru: That is an empty triangle you're making there.

W1: The page on Life and Death has a list of books. The one by Davies is the most widely known. -- Migeru

B2: I've just spent a few hours sanding shelves. I'll have to pop into Oriental Arts and see if they have a useful book

W3: forced moves are good, they save me thinking... though now I'm the one making an empty triangle.

B4: Got the fire burning tonight--literally. We're burning our beds in our fireplace.

B8: How are you today, senor?

W9: Very well, e tu come stai?

B10: Bene. Adesso devo stirare.

W1: I'll have to play better than this if I want to beat you at a handicap of 3.

W3: I should have played W1 here. Anyway, see below for how black can attack the lower-right corner before closing off this side with B2 W3 B4.

B4: Ho finito di stirare.

Anonymous: Fascinating game. What are the chances you could set the "minor edit" check box each time you move?

B6: Anonymous, I just noticed you watching. You got a name? What I know about ladders and life and death would fill a very small small thing made even smaller. If I don't check the "minor edit" box am I creating hassle for someone?

Migeru: it spams the recent changes page.

B8: "It" being this anonymous person? You got "Go" trolls? And should I tick the minor edit box? (I just did.)

Bill: Spam? I like the fact that this game shows up on Recent Changes.

Migeru: I suppose Bill's opinion trumps Anonymous'. In any case, since neither of us are logged on (in my case, because my homepage is ancient and I can't create a user account whose name matches an existing page without e-mailing Arno), the nifty "no riff raff" filter option on the recent changes page should take care of Anonymous' objection...

W9, B10: I cannot play W9 at B10 because I would find myself with a shortage of liberties (see below). Migeru

[Diagram]
Migeru v. rg game 2 (score: W +7)  

Migeru: Using area scoring, white has 44 points and black 37.


[Diagram]
Migeru v. rg game 2 (the wrong white 39)  

Migeru: after B1, white's group in the lower right has only two liberties, while black's group inside white's territory has 4 liberties. If white doesn't play at W2, black will put white in atari at the next move. But even playing at W2 doesn't work because of the throw-in at B3. White is in atari, but capturing with W4 puts white in self-atari. B5 at B3 wins black the game.

W1: Now black can't play at W7. - Migeru

B6 on the marked stone below B2. - Migeru

Migeru: Black to play, and there are lots of possibilities for mischief. Though white's lead is probably enough to win.

Migeru v. rg game 2 (the ladder at move 8)  

Migeru: Note that the naive ladder with B7 at W8 does not work, as W8 at B7 puts B5 in atari.

Migeru: What should black do now? Hint: count the number of liberties of each black and white chain involved in the fight.
