Diag.: The Big Question Mark


Welcome to The Big Question Mark!

In many of my games, I come up against a position where I'm sure I made a mistake or could have played better and would like to get the position reviewed by a stronger player. In many cases, this means I send the game to the GoTeachingLadder. But what if you only have a question about one aspect of the game?

Why not ask it here, so stronger players can stop by and comment on it?

Just link to your questions below, and perhaps add your rank information so people know what sort of answer to give.

Before you know it, we'll all be 9 dans.. ;)

Diag.: Can black live?

White to play next. Can black live in the corner?

Big Question Mark Problem 4




[Diagram]
Diag.: Is White 6 better than 6 at a?

This situation comes from Sakata Eio's book, "The Middle Game of Go", page 15, diagram 53. The author says that 6 is essential. A friend and I were looking at it, and wondered about playing at a. (See the page for a full diagram of the position.) --MFM (16k* IGS)

Big Question Mark Problem 5




[Diagram]
Diag.: Could black live?

White next. I am confused if there's a difference between white at 2-line or not.

Big Question Mark Problem 6




[Diagram]
Diag.: How should Black invade the White moyo?

--MFM (19k* IGS)

Big Question Mark Problem 7




[Diagram]
Diag.: Status ?

In an IGS game, commented at the GTL, I found this shape. Both players left it, and the commentator agreed that Black is alive. I think however that there is death in the hane at A.

Your opinions at Big Question Mark Problem 8




[Diagram]
Diag.: From a local club game

BQM9 Thoughts on White 6. 3rd or fourth line? Further 'up' or 'down'?

BQM10 Thoughts on Black 7. 3rd or fourth line? Further 'up' or 'down'?

I am not asking for 'right or wrong' answers, I am interested in a discussion on how you decide to play which move. The choice between 3rd and 4th line is not easy, but we all have to make it sometimes. Which basis do we use to make these decision?

Extending On Third Or Fourth Line lists some 'basics' for extensions - can we formulate similar ones for 'invasions'?
