find it interesting after topaz's showing of the refutation, he now thinks he has the corner with the same move i thought of. wonder if robinz will see it

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.

I can barely contain my excitement. I hope he sees the move. :mrgreen: :mrgreen:

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:

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.

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 ;-)
