A loss against a 9k

[blade90]

Here is a game I just played, I was black and lost by 13.5 points.
I think I used my time pretty good because at then of the game I had only 1 minute left.
At the beginning it already started out with an unexpected move, anyway it went surprising well even thought I made a big mistake at around move 30 or so.

I added comments to the game, as always I would like some comments on my mistakes and maybe where I had the right idea but ended up using it wrong.

P9 seems ok, though I might have been tempted to pincer instead, something like q13 because it is more severe. If he runs out, great time to play an extension from r9. If he leans on r9, you get to strengthen that stone while attacking. If he counter-pincers at say r7, p9 splits him in 2.

Your instinct response to r4 (diagonal approach) should be r3. In this case, the result looks good so you should play it. This keeps those white stones under severe attack. Even if he manages to live along the edge, you should end up with overwhelming outside influence which at this early point in the game is a fantastic result.

R6 is too close. Something like Q7 maybe. If you're going to shoulder-hit, though, try the outside hit at P6. (See also the relationship between Q3-O4-P6, a good shape). This will induce him to live very small along the edge, if he can live at all. At this point in the game, a small sealed-in life for W is extremely good for you.

@B17: p7 instead of r7. Seal him in. R7 doesn't work for him: R7 S7 R8 S8 S6 Q9 R5 R3. W will probably die.

@B55: wrong direction. You want the wall from the 33 invasion facing the open side.
@B61: just protect your cutting points. P19 isn't going anywhere and I think he will still need to play the S16 exchange to live outright here. Which because of the proximity of the Q13 stones will be gote for him.

@B75, 77: should be an approach to one of the corners. These moves are far too timid.
@B83: N15 is a stronger play, K18 is very submissive.
@B85: not necessary. W can capture a stone next with Q14 R15 R13 S13, but that stone wasn't important anyway.
@B99: too close. Attack this on a larger scale, or even better just ignore it. Tenuki, and come back to it later. On this board my biggest question at the moment is who gets the bottom; around J4 looks pretty huge for white as it is an extension from both sides. Better to get there first.
@B112: unnecessary. For the most part, the game is settled.

A few more important plays remain.
* C3 remains an interesting point after E3 has been played. My guess is that you can either get a major reduction, or live inside here.
* You can still break into W center in a major way at M14. N15 is better left unplayed, as none of M15, N15, or N14 work to cut you off. Later, L15 is unnecessary.
* I think W L17 actually kills the B group. Even after L18 and M19, N18 still kills.

I'll try to comment more later, but starting at move 38, you were right that you had some options. B39 is a clever move regardless. It is a tesuji, and it almost works here. In any case, after that move, black can still get a lot of profit from attacking the white group, which only has one eye. Black can probably manage to get stones on either side of the group. This would create some territory along the bottom and maybe build up enough strength to start attacking white's Q10 group (making territory on the other side).

That said, if you think you can kill--go for it. Here, you just misread a pretty difficult sequence--that happens, and you'll improve over time (I also suspect your opponent didn't see B39, and got a bit lucky on your shortage of liberties). You were thinking about the right things though, so I say great job!

[aurik]

Actually on second read B39 looks like it works. The key move is B45 @ P3 instead of Q4. Now you have a double threat to cut at Q4 and escape with N4, either of which dooms the W corner.

I probably would have resigned after move 50 or so. But I think you showed admirable courage in playing it through. And a 13 point loss isn't too bad. But these are just the opinions of an 11k.

Ah, I think you're right. I think white can make a ko with white making the first threat, but there isn't a threat big enough.

;W[pi]C[This move is strange I didn't really knew what to do here.]
;B[ok]C[I decided to jump towards the center with a possible pincer on Q13.

If he extends to Q14 I was not sure if I like that,
I would have played N16 or Q5.

Judicata: I like this move. White extending to R14 is fine--white still isn't safe and black can attack. Both N16 and Q13 are usually considered poor shape relative to the corner. The two-space 4th-line jump leaves a lot of aji, can be cut apart fairly easily, and usually doesn't accomplish as much as a large keima (large knight's move), keima, or one-space jump.]
;W[po]C[Here he jumped inside my moyo and therefore atacking it while extending my moyo on the botom seemed like the best move]
;B[np]C[Judicata: This move is fine. Note that white can usually live pretty easily by playing R3. Though here, it is a little tougher because of the stones at both R9 and P9.]
(
;W[qp]C[I guess he tries to live in the corner so I was thinking how I should answer? is R3 good here?

Judicata: I would immediately play R3. White ends up terribly cramped and will have to work to live.]
;B[pg]C[I decided To atack this stone first to make my position on the UR corner stronger.

Judicata: I think this is pretty good for attacking, but don't rely on it too much to strengthen the upper right. ]
;W[oh]C[strange move again, wouldn't be O11 be better?

Judicata: The diagonal isn't terribly strange. Here, I think it helps black too much on the top. White's aim with this sort of move is usually to attack on the opposite side (so here, white would try to attack the P9/R9 stones). But it is hard for white to attack, because white has two unsettled groups that are split.]
;B[qn]C[Here I decided to take away white's base and make a base for my own group just in case.

Judicata: Fair enough, but I like R3 better. Black will have to watch the R9 group, but it should be fine. R3 also secures a nice bit of territory and settles the Q3 stones.]

I decide to make this first because if I play T3 white may play S5 himself.]
;W[rp]
;B[sq]C[Judicata: T4 works too (S3 is a false eye), and white ends up with fewer liberties, which would have helped you in the following capture race.]

1. Let it escape but secure my bottom group
or
2. Try to lock it in and kill it]
;B[nn]C[This is the move I came up with to kill it, but...

Judicata: Like I mentioned before, nice move! If you thought you could kill, you made the right decision. Next time, if you think you can kill, make the same decision again (hopefully you're reading will be right). But if you doubt you can, you can get a lot of points just by chasing this group around the board.]

I lost too much and I used 10 minutes of my time already, I thought about resingning but I decided to continue.

Judicata: even without that move, white could play N2 and chase black to the corner before killing everything. If black played T5 first, white couldn't play R1, but it would just delay the inevitable.]
;B[qi]C[This move looks so slow it wouldn't have surprised me if white had played K16 or even better K4!

I thought this move is needed to secure live for this group.
Was that wrong?

Judicata: This is not needed for life. It does actually secure quite a bit of territory, but it is probably too early. I would probably approach a corner or play C10. K16 is okay, but I much prefer the approach.]
;W[ph]
;B[qh]

;W[ob]

Judicata: What moyo? This is fine, but I like the apporach at F17 better. Black has some strength facing the upper left, and can attack white if white pincers, and make some territory otherwise.]
;W[cn]
;B[cg]C[A 3point extension seemed to weak here

Judicata: Nah, the 3 point jump can get tricky, though. The solution is to start using it--let your opponents beat you up until you learn it .]
;W[jd]C[now he trys to kill this group?

Judicata: Black is alive, white is probably trying to reduce black's influence. I would pincer and approach the D16 stone, I think. ]

Wow so many comments from so many players, thanks to all of you!

I can see that you all spend a lot of time on reviewing, so I will use a lot of time rereading them
and to play of course

Some of us SDKs like to return the favor of reviews we've received, so we jump on the opportunity to review DDK games because we can actually be helpful. A 3k or 4k can helpfully contribute to, say, a 7k or 8k game, but not nearly as much, IMO.

Puppycakes creates a nice position for analysis at move 42 in the game.

In the original game, Black collapses in the bottom right.

Puppycakes gives this continuation through White 5 as probably best for White here. However, if Black stays calm and plays 6 as a ko threat, White will have to live with 7. Black captures two stones with 8 and has a magnificent position in the lower side and center at the cost of only about ten White points in the corner.

Is there more?

In PC's analysis this is bad for White because neither "a" nor "b" give White enough time to play from the outside to stop Black "c".

If the outside does not work, then we have to try the inside...

However, White also has the inside resource of the ko after 1. This is interesting because it is early in the game and neither side has any good ko threats. Black answers with 2 and the exchange of 4 for 5 looks natural. Next Black may play 6 in order to "flatten" out the White stones above and put pressure on them. The Black stones at the bottom have enough shape to fight with confidence if White tries to pull out the two stones later with "a". In addition, the play at 6 allows Black to catch the two White stones in a geta with "a" if necessary.

Can White do better?

Even if White foresees what is coming in the previous diagram, there is nothing to be done about it. White can not exchange 1 for 2 before playing 3 in hopes of inserting the play at 5 before taking the ko. Even after the exchange, Black turns at 4 anyway. If White plays 5, Black responds at 6 and, after 7, calmly connects at 8. If White now plays atari at "c", Black recaptures the ko and White's group is in atari with no ko threats. If instead White tries connecting at "a", Black captures at "b" and White has only one eye.

The final verdict is that Black missed a chance here.
