As I'm always too much focused on killing... ;-)

There is a killing move against b's lower left corner from move w106 on (and b could have defended from move 107 on). It seems not very important in this game, since w is leading anyways, but with this information it should be easy to spot...

In general you're falling prey to 2 kinds of mistakes:

a) leaving the battlefield early, surrounding a lone stone before surrounding a big group, playing what seems big before what is urgent
b) attacking from too close, forcing the opponent to connect through small gaps, thus hurting your position

The idea of peeping/poking to reinforce yourself on that side is wrong. Locally the peep almost always strenghtens the opponent. Therefore most peeps actually remain better unplayed. We play them because we like to force our opponent into an answer. In this case the peep deprived you of a grand hane and as such it was a thank you move.

Other than that, well done to win the game.

3 games played today. 1 against 6k, others are against 7k. 1 win 2 loss. But losses feel very very different. I felt so ahead in games but made 20 kyu reading mistakes overall.. I should have won them easily. At least now i feel strong..

Only game 3 and beginning of game 1 has comments, i deleted other reviews because i got too mad at myself with my reading..

Another game against 7 kyu, at some mid game fights i feel clueless, any help is appreciated as always:)
I will play in my first tourney at May 13-14th so practicing hard these days. The goal for this month is to play 4 slow games per week and finish Jump Level Up 1 & 2 (10 kyu to 6 kyu - 320 pages of questions about pretty much everything about the game)

The games will be 1 hour + 25 move/10 min byo yomi. And we'll play 3 games in saturday! 2.5 hours are given for each game, I need to get my condition up.
I also played only 2 games on a real board before =)

His 16 was wrong, but your 17 wasn't the best answer either. This is one of the favourite topics on this forum. viewtopic.php?p=161730#p161730 is the first of my posts explaining why hane rather descend is best, and I managed to convince Alakazam (a mid-dan). Some earlier posts in that thread link to older threads on the same topic. Of course your opponent was weak and the block is no good as your cut crushes him, but against better opponents the descend isn't as good as the hane if your opponent realizes blocking will fail.

Just to inform Uberdude,I learned this from
viewtopic.php?f=15&t=7273

Lecture 3 explains it. The writer claims it is taken from a professional's lesson. Of course we shouldnt take it for granted and question the knowledge. I will check the debate when i go home, i am out right now.

I browsed through the games and will post analyses later but overall, I get the following impression:

In the opening and early middle game you have a good sense of direction and apply proper technique. You also have a good mastery of life and death.

On the other hand, when you get into close combat, you keep harrassing groups from too close by, and push the opponent through small gaps, thereby reinforcing him. Also you don't always count the score and harden a lost game instead of trying to reverse it.

Try maintaining your concentration throughout the game:

- who's ahead
- where are the weak groups
- where are the big points

And avoid bad techniques like pushing through small gaps (look up this term at SL)

@uberdude if Black plays A at below sequence, wouldn't he have the upper hand? Maybe the gain is hard for me to understand because i'm sdk.

@PlaySlow: I don't follow your reasoning. If you think black's hane 1 is a mistake and white's 2 descent the correct punishment, then after some more reasonable moves from both sides it should be good for white, but you are now saying you think it is good for Black if he plays a.

So there are a few issues here. Firstly, are you correct that with a next black is good? I think not; one reason white can split at n4 later. However with the following thick block black could be adequate, if not good (could omit 5/6, depends on ladders).

Compare this to if white plays the hane and black connects (if he blocks and connects then white clamps and has a good result if black connects and a good fight if he descends, see the linked threads), allowing white to link up with 4 to the left of 2 below, rather than to the right.

Black can no longer thickly connect to the pincer stone here, a is far less effective. It's not all gain for no pain though, as white's corner is a bit weaker so black has better endgame there, the descent to s5 has a better follow-up etc, but usually that will be less important than a not connecting well / white being able to jump out to c.

Regarding that linked lovelove lesson 3, he hardly explains it, just states it. It's worth noting that series is aimed for kyu players, so will give simple rather than correct answers. As for pros saying descend rather than hane, in the linked thread someone said Mingjiu Jiang 7p said that (and other pros saying hane not descend). I believe this is an example of pro thinking changing, and the descend being the accepted move 10+ years ago. Pros like Mingjiu in the West may not have caught up to the latest thinking. As for Kim SeongRyong (the source of lovelove's posts) I would expect him to know better, so it's probably the kyu simplification here. It's worth noting that it's usually ddk's who play the bad hane and they usually block rather than sensibly connect so assuming your opponent is that sort of mistake-making ddk descend can actually work well, but I'm interested in what is the best move against a 9p such as Cho Chikun. Cho has actually played that hane in an open board, and in that case his opponent Otake Hideo 9p did play the hane, way back in 1989 (http://ps.waltheri.net/database/game/16567/). When Cho played the hane against Rin Kaiho 9p with supporting stones nearby in 1986 Rin descended rather than hane because those supporting stones meant the fight after the clamp and descend would not be favourable as it usually is (http://ps.waltheri.net/database/game/9336/).

Thank you for your detailed explanation Uberdude, now it's more clear! I would try hane in my games now; the situation occurs frequently.
