Can B still capture b6? b6 and b5 both have 5 liberties, but it seems like W will have to play the shared liberty to prevent a connection... I think it depend on what move W used to capture.

Yep, I expected as much - that's a big one. Or at least it appears to be - clearly the three D2 stones are gone, but that would be a small price to pay; he's clearly after killing the whole group (by playing B2 next), but after I play A2 (forcing him to make extra approach moves in the corner, and in sente) it's far from clear that I will lose the capturing race involving his C5 group. (Although I might well do - I've not read it in any detail yet.) Hmm, just what this game needs, another tight semeai, possibly involving a ko :shock:

I'm not giving it much thought yet, though, as responding to this ko threat just isn't an option - I have none left which really threaten to do much, so my last hope in this game is to win the ko and then try to minimise the damage I suffer in so doing.

Looks like the right move from Black, to me. I wonder what strong players think.

I agree, and by my reading, all Black loses is 3 stones. Black may just be back in this game

ok everything is going according to plan, i got a nice lead and i plan to keep it, 

when i look at the board im feeling great!, 
i got 3 1/2 corners, and access to the center, i got options everywhere

time to tighten up and stay focused :rambo:

I make robinz about 10 points ahead if he sees it, and about 25 points behind if he doesn't. Both leads should be largely unassailable with what's left of the game, so :b93: could be a really game deciding move.

Here if i understand correctly W should have ignored and proceed with the ko
i must say i would not do much better i think this is really hard :blackeye:

I agree that this has been a great game. Both players are to be congratulated, and thanked for entertaining us so well! :tmbup:

Personally, I'd still try a 3-3 invasion as black... It feels just big enough to still be able to live. After the bottom-left is settled:

There's still a ko, but I don't see any good ko threats for white.

There's still a ko, but I don't see any good ko threats for white.

Chew: I added to the diagram. Basically, white can kill those three stones, but black will have miai 'a' to live after 10... I think.

I so can't wait to read all these posts once the game is over - although it'll probably take me months to digest them :lol:

As already discussed. My current opinion is that this seems to even work, although I'm far from certain that I've not missed something. But, as it's clearly sente, if it doesn't then it's no worse than a lost ko threat, so there's no way I'm not playing it.

That makes it twice in this game that I've made a move at the 1-2 point to give myself more effective liberties in a capturing race (move 163 was the other time) - I wonder if this is a common technique, as I've not really come across it (although I do know there is a proverb that "strange things happen at the 1-2 point"). Of course, it could be that these moves simply don't work ;-)

The ko is a pretty neat idea. I completely missed it. I am thinking that this may be the biggest ko threat...
