I first wanted to extend to B7 ... but White can cut me off with a play at B9. I next read through C8 as an option, but I don't have a good way to answer B9 again. Seems like B8 is as far as I can extend in this case.

In other parts of the board, I can't help my eyes coming back to that Q2 stone. It almost feels like there's something I can do there ...

I don't think there is any dangerous aji near my stones around :b5: , so I just try to play the biggest move again.

Need to wait for an opportunity to take control ... though I haven't yet found a decent sequence of moves that I like.

I keep looking for something clever, but I don't see anything stellar. Need to just play a normal endgame, I think, and let the chips fall as they may. (Also, I'm not very good at endgame.)

In a live game, I would have thrown all sorts of extra stones at White's groups, trying to find a weakness (that usually isn't there). Forcing myself to read out lines has been a bit difficult. I haven't yet seen anything clever, so falling back to basic forcing moves to keep White from making too many gains.

I had 30 minutes of uninterrupted time to think today (a luxury) so I spent it staring at this group. I think I finally figured out how to take advantage of the aji of these two stones. I think this move will pull me enough ahead to win. Allowing my stones to connect out would be terrible for him, so he has to smother them. I should be able to cut off either the F3 group or the D6 group with enough forcing moves.
