Basically, I considered four options. Option 1:
The move above doesn't look good, because the left side doesn't seem very developable for either of us. Option 2:
The move above protects my corner, but I feel it gives him the initiative. Me enclosing vs. him approaching is big, but I'd like to keep the initiative. Option 3:
Same kind of thing as the last option. It's hard to develop big, since he got the outside in the bottom left. Option 4:
Seems like a normal move, and a big point. I think it's bigger than enclosing my own corner, or playing on the right side. |

I'd like to take some territory now. Going low also seems possible, but I chose to go high to cooperate better with my lower left thickness. |

Not sure yet, but the last one seems wrong. |

If I play elsewhere, black's approach from the left side will have two purposes: to strengthen its left side and attack my upper left stones. |

@Observers Would something like this be playable for white? I think it severely weakens the aji that black's stones on the left have. I think black wouldn't play 23 after white 22, but that only shows that 3-3 is not as important.

What's the status of W's lower left ? It doesn't seem too weak to me, currently. But is it thickness ? Unclear to me -- if B gets a move like ...
uPWarrior, C17 seems pretty big... I wonder if Bill is watching, and about his assessment. Also, B has this kind of option:

Why not? Maybe I could tenuki, but for what? |

I could go one step further, but then black's tiger mouth at C8 would be a strong move. Black can still play the same, but now its value is weakened, and I can attack more smoothley later having a stone one step further. |

The two black stones in the upper left seem safe enough, but the three black stones on the left look useless when white plays on the left side. Does anyone else think that black missed this one? |

Still thinking about this one. I have to keep in mind white's privilege to play the following:
Which means that my three marked stones have potential to be attacked. I can play a move on the right side, but the question becomes, can white's attack on my three black stones compensate for the gain I get by playing first on the right? If so, I should consider an alternative. |

So some ideas:
Helping my group seems nice. Taking profit on the right also seems nice. |

I don't know if I would normally play this way, but I think it makes sense to help my group. My reasoning is rather simplistic. 1.) If I help my group, I have no other weak groups on the board. 2.) A simple continuation is like this:
That's something like 30 points for white in that area. I have a similar amount of points, and if white plays on the right side, I can take initiative. Seems somewhat balanced. He's stronger than me, so it'd probably be good to avoid having weak groups. |

He's stronger than me, so it'd probably be good to avoid having weak groups. Locally, I preferred the cap to this as a lighter move. I feel this could quickly leave black with a heavy group that's not doing much. Globally, if black plays to build up something on the right, white's only potential at the moment is the left side, and feels a bit like putting all your eggs in one basket. For white to remove all the aji on the left would be too slow right now, so black can wait until later to play there. |

If I respond by standing up, it'll make black's group stronger, and playing elsewhere seems bad. |
