Life In 19x19

Thanks, Bill! What is the meaning of B221 at A10 in your variation? Is it because black cannot win the ko that'd result if White A10?

This is the game in question. Could white play at B213 instead of protecting at 212? I'm not good enough to make the last 28 moves, since changing the order will affect the outcome, right? I'm running a simulation now but it'll take time.

Thank you all for your comments. It is certainly much ...

Hey Uberdude! I just came across this thread and wanted to say I found it quite interesting. Thanks for sharing, especially the pictures!

Ah, black E18, right? Sigh. But that's after white's group is closed in. Why does white need to do this right away, instead of playing elsewhere and waiting for black G15 and E16? Can black reduce white at all *before* surrounding the group?

I'm sorta embarrassed to post this, since I must be missing something really trivial. But I couldn't find it, nor could MFoG.

The text says "Black plays the hane at 209 (G19), White blocks, and Black connects. White protects at 212."

Why can't white protect at E16 (B in my diagram)? And what can ...

Yes now I see the problem - how embarrassing to have spent so much time and written a post without noticing :\. And now I also understand how it may be more valuable to keep sente than kill those two stones. Thank you everyone.

In the description of the problem, he says "It would be a pity for white to hane at a (P19) in the endgame."

What I don't get is why black plays S16 instead of Q17, or if unconcerned about the two stones, just play somewhere else instead of S16. S16 leaves those two black stones vulnerable if white ...

Sorry, blacklisted for that turn. Otherwise both players could just infinitely choose to play a critical point. So they need to play somewhere else first, then can try to return to that point.

I found a brief description here:

I'm 18k on KGS but I think it's wrong and I'm probably more like 20k. I think I won due to dumb moves like W34, W94(?) and W176. and things like not playing into the bottom left corner which on review, seems wide open. Like what if W64 had gone 2 down and to the right? A lot of times it felt like W ...

Does anyone have any analysis or details on games of Go played concurrently? Not simultaneous games against multiple people, but when both players "seal" their moves and play at the same time. If they pick the same space, then that spot is blacklisted. Captures get resolved simultaneously (so a seki ...

I believe this is from the Janice Kim Vol II Way of the Moving Horse book.

Problem life and death #21 beginner, on Hactar Go. After move 5, it says solved, but isn't it just seki? I understand, that's a better outcome than dying - is seki usually considered life in such problems? Also, is my evaluation right, is this seki?

Thank you for all the replies and information!

My daughters (5 and 7) seem interested in Go and can play a bit. They've solved a few hundred problems on GoChild between them and seem to enjoy it. This year I setup a private school for them, so I've got quite a bit of liberty in selecting curriculum. I think it'd be neat to give them ~2 hours a ...
