Strategy and Thoughts

It's worth a couple of points, and unless he wants me to cut at C3 and rip his corner open, it's sente too. Then off to the bottom edge to complete the sente reduction of this corner, before jumping off to the right and seeing if he's going to respond to S6. Even if he doesn't it's very big gote.


Tactics and Variations

If he tenukis completely, "a" is a ladder, else I use "b" and "c" for damage dealing:

Strategy and Thoughts
See my last post, under tactics and variations, second diagram. The order is reversed but it would be easy for white to revert and end up capturing those two black stones.

Yes, empty triangle is ugly. But this is a case where I think it's the strongest move.

Not for the players...

This is a clear case of thinking too hard. It's actually a horrendous move, which is very poor. White's clamp still works in the corner, and black has made a horrible shape.

It's surely bigger to protect the corner solidly. Trying to get an extra point like this is a good way to end in pain.

Strategy and Thoughts

Well, if he insists that I keep sente for all this, that's fine by me. The cut still works now (and I'm deciding about that or the clamp at B2. The concern is B2 feels gote, so it's a move I want only when the sente is gone, though it's obviously very big), and I've picked up an extra point. Not only that, but now I'm staring at all sorts of cuts if he lets me keep pushing. What he should have played is as follows:

I can't bend round easily at "a" as he can just block, "b" is gote, "c" is sente but the followup I want at "d" is gote, and the cut has gone. There's nothing wrong with fixing all your problems and keeping good shape. The empty triangle is just bad here.

My initial reaction to black 139 was "ewwwww."
That which can be destroyed by the truth should be.

I'd like to take sente, but something like this is more points than I really want to give up. And that's assuming there isn't a way to take the corner I didn't read out well. I'm wary of just following him around the board, though, so I'll keep an eye out for a good place to take sente.

Strategy and Thoughts

Carrying on my sente fun and frolics. Will play on the right next, and if he responds, I'll clamp at B2. If he doesn't, I'll see what fun and games can be had on the right. For one thing, I can probably play S4 (normally gote) as a sente move, and that'll give me a good amount of endgame on the right side...

Strategy and Thoughts
I don't want to get in a situation where I follow him around the board, but I think this threatens more than just some points of territory because of the aji of the empty triangle (still think it was a good move, though).

Actually, I don't have enough liberties for the clamp anyway, so I'm going to keep picking up my sente points for a while

Strategy and Thoughts
See my last post. If I ignore to take sente I force a sequence that I am afraid white can use to take a huge chunk of the corner, if not kill it out right.


Tactics and Variations
So the reasoning behind my forcing move. Basically, this is a uncomfortable position for black but I don't think white has anything. (We'll see soon, I guess :))

If white ignores, though, I still can't kill the bulk of white's group. So it's a big move but not a 100%-absolutely-must-answer for white.

Same as before. Black could have prevented this with 149 at C2. After this sente, off to the right hand side...

Trigger: if you defend against 157 at either J2 or K1, 159 takes the ko back.

Strategy and Thoughts
I think he's treating this as a forcing exchange. There isn't a really great followup locally that keeps sente.

But he's chipping away at me by 2 points here and there, and I need to start monkey wrenching some of his plans if I want to win. So I'm going to go for the ko. Given that a whole quarter of the board are my dead stones, I should have way more ko threats than him.


Tactics and Variations
This was my original thought for a good solid 30 minutes. White doesn't have a local sente followup.

But I went for the direct ko for either side. I think I'll probably win the exchange, dangerous though it may be. It should gain me something like 8 points vs. just defending. If I lose the ko without adequate compensation, I lose the game.
