6k in need of outside input

This is my first post on L19, although I've been following it for over a year. I've been playing for 15 months and am currently 6k. I've become more serious about the game and recently changed my study schedule.

For the first 14 months, I played 4-8 games a week, reviewed my own games, and studied randomly. Now, I play 5 games a week, each preceded by an Internet Go School lecture. I continue to review my games, and do 60 minutes of life and death on the weekends. All games are 5+5x30.

I would greatly appreciate if stronger players could review some of my games. My training so far has been in almost complete isolation. Once I'm strong enough, I'll return the favor and help others with their reviews. I'll post games every week as long as people are willing to contribute.

I've attached two games I played this week. Variations are pieces of my review.

Thanks for your help!

first game
move #45:
when you are being attacked there are many moves that will give you points before you secure your life.
white attacked with #44 which is wrong timing.
this is a perfect timing for you to play B19 endgame.
Stronger players will not miss such golden chance to gain points.
combination of few points here and there will decide the game.
after you secure your life there is no guarantee that endgame will be your sente.

hope that help.

Really appreciate the comments, all of which were extremely helpful. I've included specific responses below.

By the way, great study journal SoDesuNe. Way to keep at it.

Magicwand
Game 1
You make a great point, and B19 is a move I would not think to play. Thanks for the reminder on securing points while making eyes.

Bill Spight
Game 1
9: I'll play R12 instead next game.
13: I also prefer C10; I tend to invade too deeply when I give white a large framework, and am increasingly playing for as "scattered" of a board as possible, instead of mutual frameworks
21: Good move, thanks for the follow-ups.
33: I don't think I should've invaded D17 to begin with. H17 to invade, J16 to reduce. I need to improve my reducing game.
50: Thanks for your analysis. That's exactly how the game turned out; his outside thickness led to significant territory. The attempted D17 invasion was mishandled.
51: Very interesting plays at P9 and P10. P9 doesn't usually come to mind, let alone P10, but they will next time.

Thanks Bill. A game review from a high dan is extremely valuable.

SoDesuNe
Game 1
7: I agree, and wish I'd played C. Bill Spight agrees with you as well.
9: Good points. As you noted, I looked into B and like the direction that takes me.
12: He does develop faster. I have a tendency to develop slower and fall behind early. Being outplayed in the opening.
14: I thought the same, as I'm pushing white into an ideal formation. Should've played F3 at C10.
16: Leaves me H17, which I only discovered in the review.
21: Thank you for playing this invasion out. Less obvious to me than to others. Very helpful.
33: A is phenomenal. Hadn't thought of it at this moment, and it's a great move
41: You're absolutely right
45: Very beginner move, I agree
51: I thought a while before moving 51, and agree that there are much bigger moves. F6 and R12 were both better moves. Bill suggested P10 or P9.
59: Agree with A and B.
97: Hadn't thought of this. Thanks for playing it out. Much better.
123: Me either. I was trying to complicate the center without reading it out. The following sequence proves it…

Really appreciate the comments. I'll be on the lookout for updates to your study journal.

Thanks again for your previous comments. I played in my first AGA tournament and made 5k on KGS this past week, so your reviews helped tremendously.

I've attached two games I lost last week. I'd greatly appreciate your thoughts. Variations are from my review.

Thanks!

For the first game:

Move 19: Black chose to take the corner at the expense of his side group, so that means white needs to trash black's side group instead of defending the much stronger wall. As soon as black's side group strengthens itself, this changes from a great result for white to a poor one.

Move 22: Small. If you're worried about the white wall, approach the UL corner from the top side.

Move 40: White has been making influence based moves so far. Taking 8 points here is small compared to the influence black gets to counter white's. White's S12 group can severely limit black's territorial prospects here, so there's not much to worry about.

Move 44: Why not Q5?

Move 54: This seems to start the middle game, but there are still big moves left, like an approach to the top left stone, and an extension from white's wall on the BL. Getting the last move of a section of the game is important.

Sequence to 64: This is good. Black should perhaps have let himself be cut and run.

Sequence to 95: It's better for white to keep black's two stones cut and give black the side. This sequence gives white 3 points in exchange for most of the potential that white's wall had.

Move 96: White has enough influence on the top and right that I think white would be better off playing border plays like F15 and O5 or so, to expand his moyo and limit black's. A cap or so may also be good. Invading like this helps black build strength to reduce white's moyo after the dust settles.

Some 1-kyu-ish comments =)

i will not go overboard on what is wrong with your play...
game 1:

let's take a look at move 20:
Q13 is better shape than your move. learn that shape for the future game.
Q13 will almost capture that stone aji free.

78: almost always capture the stone he cut.

there are many moves that i didnt like but above can be fixed by solidifying your fundamental knowledge of shape.

word of advice...
if you can not read how you are going to live in your opponent's influence...do not choose that path. only play what you can read and are comfortable to play.

For the second:

Move 22: Why not jump with a knight's move to stay ahead? White has to struggle to live, and black gets to erase a lot of white's influence, negating the moyo strategy.

Move 31: Why cap and then tenuki to invade here? The other order makes more sense. In any case, white seems to have chosen the wrong direction.

Move 40: Give up 4-5 points to make a base so you don't get pressured as much and cut off the white topside stone.

Move 45: Why play this if you don't intend to cut?

Move 51: No complaints about specifics if you choose this route. There's less aji than with the ogeima for white to exploit.

Move 57: What about H14 to get out in good shape? Black's group is still not alive and is between two strong white groups. In the sequence that follows, black has two weak groups that are split by a white one with two strong white groups on the outside. It's inevitable that one or the other black group will suffer.

The rest of the game seems to be an extension of this fight, where white can reduce black while threatening black's weaker groups.

Actually that is a common probing technique. White's Keima ends up in a bad place after the 3*3-invasion so the exchange is very good for Black. If Black invades directly, White will most likely don't answer with this Keima when Black caps again since there is already a strong wall backing up a more aggressive move.

Hmm... don't think I've seen it before. Thanks.

Some comments on the second game:

27) Your move is playable, but I would keep pushing. It is important to strengthen your center cutting stones. A sequence like K4-L3, L4-M3, M4-N3, N4 would be great for B. White could try K4-L3, L4-M4, M5-N5, but then N2 would still be good for B.

29) Your move at M3 prevented W from making a base here, but induced W to attack your center stones. A natural continuation would be something like J6 or H7, leading to a running fight with equal chances. If W gets to play here first, J5 would make it very hard for B to save these stones, yet they are really too big to give up.

39) Block at B18 (but first verify that W has no profitable cuts). Letting W get B18 in sente is intolerable.

No comments on the long middle game fight ...

119) The diagonal move Q6 is nice. This attacks W eye shape and also makes more territory than the game move.

199) Playing F7 is roughly 15 points better.

Really appreciate all of your comments. I spent a good deal of time reviewing them, and they're helping me begin to detect common threads in my mistakes.

I've attached individual responses below. Have a great weekend everyone.

skydyr
First Game
19: Absolutely; move 20 should have been at Q13, or playing elsewhere with F17 or O3.
22: Same with this move; far too small, I agree.
40: SoDesuNe agrees with you too. S12 limited black's potential here, and taking the corner isn't as strong as continuing the push at K4.
54: Splitting these groups, although it eventually worked out, wasn't the right decision to begin with; the top left corner is screaming for attention.
96: Yeah; this was far too deep and unnecessary.

Second Game
40: mistune (5d) agrees; allowing B18 in sente is terrible.
45: No need to invade here, but if I did, but if I did, a couple moves higher would've been better.
57: You're right, H14 would help get this group out with good shape.

Magicwand
First Game
20: Q13 was absolutely the right idea here. Other reviewers have said F17 or O3 would also work. R15 was slow and weak.
78: The morning after I read this comment, Guo Juan said in one of her lectures to "almost always capture the cutting stone." Thanks for bringing that to my attention first!

SoDesuNe
First Game
16: R17 is much better than what I played; I didn't even think of it. Thanks for bringing that to my attention.
20: Almost all the reviewers agree; this was slow, and would've been better at any of the spots you suggested.
28: You're right; if black would've followed joseki, I would've been in trouble.
36: I worried about the cut at H4 after the sequence you gave.
40: I agree with A. S12 limits black's potential on the right. Continuing to push might be better.
46: Thanks
52: Agreed; A was connecting living groups and not necessary. I'd play D if I had another chance
74: Didn't see this; A should've been clear.
90: Ko, that's great. Didn't even see it. Good catch.

Second Game
7: I've played A in 2-3 games since seeing this comment, and it is much more comfortable than Q10.
8: This was an odd move.
27: Great principle, and you're absolutely right. M3 does almost nothing.
43: Playing A should've been instinct. Thanks.

mitsun
Second Game
27: I definitely should've pushed. Playing from the strong side while pushing white into a soon-to-be heavy black group was bad.
29: J6 or H7 were both great ideas. It seems neither of us recognized the importance of playing here.
39: Agreed.
119: Very nice, I should've read this out. Played a 2 space low extension without thinking; very beginner.
199: I can't believe I missed this…thanks for bring it to my attention.

I'm considering switching my current balance of lectures to games from 5:5/week to 3:7/week or 2:8/week. Reasons are to get in more games, and allow increasingly challenging Internet Go School lectures more time to sink in. Any suggestions would be appreciated.

I've attached two games I lost last week. Variations are pieces from my own review.

Thanks again for your help!
