Life In 19x19

I just played this game on GoShrine and it was very fun and exciting.
I'm White and I did win but it was very close and I'm sure I did some mistakes.
I hope you can point out my mistakes such as: live & death, slow moves, wrong direction, bad shape, bad exchange and so on.
Maybe you can also tell me what I did right, if I did something right

I think it's a very exciting game since the balance of territory and influence are shifting at large margins.
I'm KGS 6k and my opponent said at the end of the game that he is KGS 3k. Time was 30 minutes + 5x30 byoyomi

Well here is the game:
About :w94:

I did answer this move because I was leading by so much but was there a better answer?

Edit: I liked D11. And generally well done on handling the tricky shenanigans that went well, all of that was hard.

Thank you Loons, your move for 118 is so simple but also a lot better then what played.
Your comments help me and I can focus on praticing reading, since I made some big eading mistakes like 128 (what I wanted was obvoius but I never expected 129).

As for you suggestion about move 10: could you explain why outward influence is more important here? I'm a total territory oriented player and I'm not good at using influence right :oops:

Slight differences in opinion for :w10:

10: With apologies to Loons, it is not at all clear to me that 10 should be at F4. Indeed, if you count the high white stones -three - and the low white stones - one - it suggests that in the interest of balance white ought to play low.
Neither is a bad move. At 6K, flipping a coin is probably a fine way of resolving the issue.

14: This is a tad conservative. Pros tend to favor the more expansive C9. In this position, with a lone D16 stone still a long distance off, you probably would do better with it. Conversely, if he had an additional stone - at C13 for example - then your play might be better.

28: You are not strong enough in the corner to play this.
N5 or O5 might work here. E14 is a big move for both.

33: Ouch! You have one weak, eyeless group, and a corner that is starting to look attackable.

34: O3 is the honte move here. Not only is it stronger defensively, but it prepares M4.

42: If you really want to make this separation scheme work, you have to play S6 here and S5 immediately thereafter.
This is not Iraq. You do not have to send more stones in just because the prior ones had an unachievable mission.

52: This is completely the wrong direction. It is a good play against a 2-space extension when you have him blocked at both ends. If you had a stone - or even a solid group - at J17, this might be good. As it is now, it is just aji keshi.

91: The last two dozen moves have been strategicly dubious play by white. You are attacking with two eyeless groups, and if he gets out by pushing between them, one of them probably will die. I'm too lazy to read out what would happen if black had seen the obvious shape move at M13. But it would not have been the game-changing kill as it is here.

96: Why add a weakness when you are under attack? Play the solid T4. Then let him try to live when he has one stone up against your 4-stone wall.

97: See why it is weak? Now he can add another stone in sente. That is the equivalent of letting him have a free move.
Let's do some tewari analysis here. Suppose that you had played 96 at T4, and then he had played 97 at T2. In such a position, would you ever even think of playing 98 at T3? Of course not. You would play something like Q2 and probably live in the corner.

99: If you had played O4 at O3 many eons ago, you could laugh at this move.
This position is a good opportunity to learn about shape, and to see how seemingly innocuous moves can cause you to live or die 50 moves later. I recommend setting up this position on a board, with the stone at O3, and treat it as a life&death problem. Then set it up again with not only O3 substituted for O4, but also removing T2 and T3 as if you had played T4 straightaway. Then treat that as a life&death problem.

Thanks EdLee! That cleared move 10 and 20.

Thank you Joaz Banbeck, that is really helpful!
34: This move really hurt me later, I wis I had played O3.
42: :lol:

91: That is true, since I started to play on Tygem I got this really bad habit of being too aggressive.
96-99: These are great comments, and I can learn much from this. I'm really going to set this up :study:

Thanks again for the great comments Joaz :bow:

Ha ha, I'll concede to Ed on :w20:

& Joaz on

. My thought about 20 was- I was happy it was not low.

My general reasoning for 10, if anyone's interested;
