Some more games tonite. I won an unexpected game with Black tonite, i feel so behind after move 40. Tried to catch up and white helped in some moves.

I keep solving Go Problems and keep playing everyday but it's getting hard since i got a new job that keeps me away from 8 am to 8 pm. But i like the game much more, maybe because my time is limited.

Always fill the dame.

Take another look at the bottom left corner. What do you think? :)

It is worth playing around with to find out what can happen when Black plays there first. :)

:b69: should be at Q13. Black has M12 to connect to. If both sides run out, White still does not have eyes. Black needs to see the upper right as a very strong position to push White into.

:w82: is a terrible idea, cutting two live black groups. In terms of shape, Skydyr's comment on 83 is correct. However, in terms of gamesmanship the game play is better. Black misses a big chance when White connects at 84. :b85: is absolutely meaningless, making one point in gote. Black should play to cut off the three White stones at the top. There is an excellent chance that they will die.

Black 119 should be N5 just for the heck of it. Force White to answer and then see what you are going to do. The game play is a completely wasted stone.

Another game. I got a few questions and comments at moves 43 and 71. I was white this game. Feel free to bash me.
And move 12 should be at S17, i totally forgot the sequence.

The stuff relating to :w12: and after, you did get a bit lucky that black didn't exploit your weaknesses which you identified, but you got a good result.

K17 at :w26: feels off. It's too close to thickness and too low to be there, I feel. I'd be tempted to make a corner enclosure like F17 or F16 maybe. The left side star point also looks good.

At :w28: you may want to approach from the top directly to pick the direction there instead of letting black do it. The game area is fine too, but I'd rather play high (4th line) to control the center, since black will later be able to cap this stone to reduce it and help him invade white's moyo on the top.

After :b43:, black has taken the corner and shown that white's stones aren't efficient. White would much rather have K3 at K4. I like C a bit better than the game move, since it could isolate the left side stone.

The sequence following the cap has too many weaknesses for me to feel comfortable as white. It feels a little too direct.

The trade through :b71: was ok. White lost a bunch of points, but the outside became strong.

:w72: was fine, and through :w80: was good. You could just extend for :w82:. At :w92: you should block black while connecting with the tiger's mouth. Looking towards killing was fine, and white's been profiting through the whole attack on the top and the upper left corner.

:w94: and :w96 are iffy shape that leave weakness. White 103 should likewise be E18.

White 108, your assessment is correct.

Later in the game, you like to leave stones hanging in atari. This is sometimes good, but you need to make sure that the capture isn't a bigger sente or a big gain for black. The ko was completely unnecessary and quite likely lost the game.

Another game of mine, pretty straightforward one. Got some questions about how to punish deviations from 4-4 josekis.

What questions? You played sensible shapes, he played silly ones. Good job. Only comment I'd have is I prefer p10 at o11 so his centre turn isn't sente (there is a minus with his 2nd line hane connect). A question for you though, when you played 60 did you have a plan for his cut? Your hane is a strong move, but only if you know the tesuji to deal with the cut (the g3 stone helps him a lot here).

I should have been more clear, my questions about the top left and bottom left josekis that he deviated.
About move 60, i got a plan but no tesuji involved i think.

E4-E3-F3-E2-F2-C2 (white can capture cutting stone and can get to the center. I think it's not a very good sequence for White, right? Because Black will gain strenght attacking white group. Which tesuji u are talking about? I am very curious now:).

Agree with uberdude. Game was lopsided. Black did not try to win.

About the cut of 60, you can't capture black's cutting stone as 5 is atari:

$$ +----------------[/go]


But by putting in the tesuji hane of 2 first, if black answers normally (there are some resistances but white can still do ok against those) then that atari from before means he loses the other 2 stones:

You can come across this technique in the following joseki variation (a good example of learning shapes and tesuji from joseki):

Thank you Uberdude and Knotwilg for comments. I know learned the tesuji and continuations, I believe. I repeated a few times the similar sequences.
@Knotwilg, W78, you indicated I can hane. I didn't hane because the ladder does not work. But since my both groups are alive, I can afford to play aggressive and hane, right?

Does black have a ladder that works?

I meant J11 cut. I thought i should have killed it with ladder but knotwilg explained the situation.

I have a bet of playing 1 game (at least 20 min main time) each day a month with friend to fuel me up. If I lose i will buy him a go book each month. Bad thing is that my new work takes so much of my energy. For example this week i slacked in problem solving.

Another game i played can be found below. I reviewed game myself and found a few sequences, but not posting them since sgf file is a mess now. I am just posting the one with some questions inside. I felt I didnt abuse his weak groups.

On move :w42: there is a tesuji which keeps white all connected. Could you find it? ;-)

You mean all white groups or groups at the right side?
If all white groups i'd play at E15, if you mean right side groups i'd play at M13.

I should add "keeping my groups connected even the move is slow" to my checklist maybe. If the groups are not alive yet of course.
