Yep I meant M13. In the game black first cemented your area by useless exchanges ( :b61:, :b63:, :b65: :scratch: ) and then started to run with N13 afterwards, which did not work well. However N13 is more dangerous than it seems, I have added a few exemplary variations at :b49: (and would appreciate corrections if I missed anything!). Note that this also latently threats the L16 stones. Of course N10 at :w50: is not the only possible answer, and I have not analyzed all possible variations. Therefore it is not necessary for b to do that right away, he should continue elsewhere (thereby paying attention not to strengthen the area under question!) and wait for a good moment for exploiting that aji.

Go to move 49:

Hi PlaySlow,

:b15: D4 is natural. After W replies, then you extend to C6.

:b17: This is unbearable.
When :w16: at D4 ( which you missed ), it's bad enough you have to reply at E5.
But this shape is terrible.

:w42: Bad habit.

:w44: Bad habit.

:w50: , :w52: -- W has developed this bad habit for some time. ( Probably nobody told him about it. )

:b57: Which side is better ( more useful ) for B ? J7 or K6 ?

:b59: note -- W is not being greedy -- you allowed his :w58: .

:w62: Locally, between A or B -- of course block directly at B.

:b67:, :b69: You mentioned the proverb hane at the head, :b65: . Did you consider hane at the tail ( J18 ) ?

:b75: Find the correct move and sequence. ( Your note at :w74: is incorrect. )

To improve our understanding of shapes, contact fights, and reading,
we must put in the effort. Study the mistakes. Not only once or twice.

Otherwise we'll continue to make the same errors over and over again.
( Like W's bad habits. )

In move :b83: there is a very simple way of keeping the N18 stones alive (Hint: count liberties!). With that move black's position would be rather on the winning side IMHO.

57: Totally my bad, i understand. I played fast there:/
59: I didnt mean that specific move, the sequence of moves where W tries to kill my group.
67-69: I considered it, but thought that J18 would single out my J15 stone. When i review game now once more, it doesnt seem like it.
75: I should have ataried. P17-O18-N18. The thing happened in game is honestly when i reading that sequence, i forgot i got a stone at P17, so i thought, oh W can play P17-O18-N18-Q18. It feels stupid. Most probably, getting scared of Tygem and near fighting makes me read nervously.. Maybe a mental thing..

Belly tesuji, P18 right? It seems so clear now, i dont even remember why i disregarded that move in the actual game.

Are you on blitz time settings ? If too fast, use a slower setting --
give yourself plenty of time for crucial moments, to read it out.

I play with a minimum of 20 min main time and 30 sec byo yomi. It's more like not trusting myself. I will try to read more calmly. I should assure myself that my opponents are 9-10kyus and not all of their aggressive moves are right. They are in fact very abusable and leave many weaknesses behind.

Forget the top right, in the first game the black group on the bottom left was dead for half the game until white forced it to make life with a series of bad moves. What would happen if white had extended to atari with the stone in the middle of the group?

The i defend the cutting stone and then capture the extended stone? Didn't understand what you mean to be honest? Am i reading it wrong? I am talking about the situation after move 54.

Whoops, nevermind. That's what happens when I'm doing multiple things at once.

Hi PlaySlow, as a courtesy to anyone volunteering their time and effort to review your games,
and to any readers in general, may I suggest you make it very clear what's your color in every game you post here.

It's one thing if your forum username is identical or similar to the one in your games.

But you have multiple, unrelated usernames.

( Or, we can see your alternate usernames listed in your profile on the left. )

People can of course click 'Previous' enough times to look for previous clues,
or deduce your username from 2 different games based on the one shared username.
Some folks may even enjoy the mini mystery and puzzle.

But it's much more efficient if you spell it out for every game --
then we can dive straight into it.

You are right, sorry about that. I am using "Wretched" nickname on those games.
I also uploaded the handles on my user profile.

Opening

10: how to take advantage of Black's noseki?
14: common technique to indirectly maintain a cut
25: overall Black seems to have the better opening but not by a lot
31-37: you get a good result by taking advantage of black's mistake

Middle game

48: the same technique as mentioned at 14 is available
66-76: White is very timid here. Black's groups are weak but White concentrates on living instead of cutting.
Sometimes keeping the opponent weak is a good way of strengthening your own group.
82-92: White gets a very good result out of what was initially a move too close to opponent strength
99: Black comes in too deep and
109: tries to save all his stones, eventually losing all of them
110: game over

There is no more opportunity for Black to reverse the game so didn't bother commenting on the rest.

Detailed review

Another game of me at tygem. I was White this game..
I got a few questions only although i am sure i did a ton of mistakes.. Especially in the endgame. But after 5 straight losses due to simple reading errors it's good to win..
Edit: We counted W+2.5 at the end so he resigned.

Hi PlaySlow,

:w28: OK for these levels, but he ignored your approach; this feels a little soft.
Did you consider to double approach his corner ?

:w32: No. Either connect solidly E3, push up F4, or extend G3. Not this hane.

:b33: You got lucky. He should've punished you right away -- push at E3 then cut (you have 3 cuts!) -- your shape collapses here.

:w36: Wrong shape. Your N3 group is not settled either; so each side has a weak group.
Your C shoulder hit is better than your game move.

:w40: A right idea, I think. But it feels "pushing from behind". Maybe one higher, at L6, is better ? Get in front of your opponent.

:b47: Strange shape. At least L7.

:w60: You HAVE sente (at :b59: ). Think about this for a moment.
If you tenuki directly on :w60:, B cannot get that excellent eye shape in the game.

:white: 120 Pass. Do you need 3 eyes to live ? :)

What is the meaning behind :w16: (N15)? One purpose is to create or expand a moyo along the right side. B promptly squashed that plan with his next move (R8). If that was all there was to your move, then this would be a bad exchange. But there is a good followup in another direction. This vital point is big enough to play right away, or at least very soon. Both players left this situation alone for too long. It would still have been an excellent point to take when you suggested it 50 moves later.

:b21: is usually not played this early, so it is probably not a good move, but I am not sure there is any great punishment to be found. The game sequence gives W perfect shape and leaves B somewhat overconcentrated, so you should be satisfied. You could try something drastic like Q5-R5-R6 to punish B for not connecting here. If B simply connects at R4, you connect at Q6 for a great result. Try playing out some of the more difficult continuations and see if you like the results.

:b27: seems greedy. The W approach at F3 was not an overplay. If B responds normally at C6, and W then comes back to J4, W would not have too much territory here. So I would look for a more aggressive response than simply jumping into the corner. A double approach would be quite playable, as Ed suggested. Or simply jump to F5, making miai of D6 and J5.

For similar reasons, :w32: should be F4. :b35: should also be F4 -- just look how flat and small and inefficient the W position becomes if B presses here a few times in sente (giving up the J3 stone, which would have earned an honorable death).

:w36: is still the right idea, but it is a shame to have strengthened B so much on the left before this move. No chance for a double attack now.

:w40: at J7 would be interesting. B might have a hard time surviving this attack. Note that even though B is strong along the right side, you do have some forcing moves like R7 and Q5 to gain extra strength.

The exchange :w48: - :b49: was bad, as it hurt the lower left corner. There is now a severe weakness at E2, though neither player seems to have noticed for quite some time.

:w60: is a nice tesuji worth remembering, but in this case just igoring the B move would be even better. Was B really threatening anything? And if you answered simply at L3, I suspect B would have replied, letting you keep sente.

For :w66: you suggested a few moves. "A" would be very good, as would a similar extension in the other direction. "B" would be superb, finally making good use of your N15 stone. "C" and "D" both seem too slow, as both B and W center groups are alive, so there is no attacking purpose.

Another idea would be to look at the B group on the left side and think whether you can profit by attacking there. C8 looks like a nice invasion point, backed up by your stones above. If your reading says that this move does not work directly, would a preparatory play at C12 make it work? Maybe you could exchange C12 for D8 in sente, then come back to get one of the other large moves. Look again at this invasion around move 96, when W has become much stronger outside.

For :w70: I think I would just play E17, taking the corner profit and preventing :b69: from making a base. W should then do fine in any fighting. B probably has to connect underneath at K18 (which the game move did not prevent).

:w92: is a strong move, but only if W is willing to fight the ko. This would be a good time to pause and count the game, and also to count large ko threats for both sides. Tenuki is also a good option, saving you a full move if B gets nervous and defends before you start the ko.

Mitsun and Ed make great points about opening and middle game. This game however was won in the endgame. Why and where?

At 174 White takes the biggest point left, which was the last of the 5 major endgame moves discussed at 132. This secures the game.
Both had opportunities to grab the move and the game.

This is a very good endgame strategy: try to identify the 5 biggest remaining points and grab 3 of them.

Detailed discussion from 132 to end:

I didnt think i got 3 eyes at that moment, thought i got a false eye at the bottom^-_-^, silly of me:)
