Second weekend in class D

Right after my trip to Innoshima, it was time for another insei weekend. Right now I’m at some kind of a stress peak, having had a great deal of things to do, but starting tomorrow I’ll have a reasonable amount of free time again.

I played six games last weekend, against the insei numbered 12 and 13, and then against the ones numbered 1-4 (them being the ones who dropped to class D from class C this month). The former C-classers were indeed quite strong, and I lost my game against the one ranked first. I’m including the kifu of that game in this blog post.

On Saturday evening, I encountered some extra trouble after the crown of my front tooth came off. Luckily there was no pain, however, so I went and attended the Sunday insei training anyway. That was for the best in the end, as the broken tooth provided no extra complications, and I also won all three games, against the insei ranked 2-4. The second-ranked insei actually for some reason didn’t come to play the game, and I got a default win. In the extra time, I got to play against Sakai Maki 8 dan, one of the teachers, and we had quite the interesting game. We ran out of time again in the late middle game, the situation being close at the time. The two following games on Sunday were both interesting — both insei fought back well — but both of those games ended in the opponent losing a big group, forcing a resignation.

Yesterday on Monday, I booked a time for a dental clinic, and since my case was an emergency, I got in on the same day. Forty minutes later, it was as if the crown never came off in the first place.

Here’s the D class results update:

With a winning percentage of about 93%, it still seems reasonable to say that the opponents are on average two-three rankings below mine, at least if using European Go Federation’s ranking standards. The four strongest insei seem to be in a different class though; perhaps their playing level is close to EGF 5 dan.

Here’s the game I lost:

Having gotten to play a stronger insei for a change, I went experimental style right in the opening: I already approached a black corner with white 4, wanting to see what black would do. White 6 is usually preferable at d15 instead, but I wanted to see what would happen. The white 6 played in the game still doesn’t give a noticeable advantage to black.

White 20 may look like a peculiar direction of play. I chose this direction, because the black upper-side group is already incredibly strong and alive; the black approach of p17 has quite limited gain. If white played the other 3-4 point instead, black would be happy to approach from the right side. Instead of the white 20 played in the game, r15 seems possible as well.

White 22 is another move that I wouldn’t play, were the win extremely important. I wanted to see which side black will pick. Normally, in this kind of a board situation with there being a possibility of a black lower left moyo, I’d play o4 instead to prevent it. The white 22 played in the game is a good move too, just not my usual style. As expected, black chose the lower side with black 23.

White 56 was a reading experiment, then. White earlier gave some points on the lower side for a very solid position, and black e3 was a mistake, losing a liberty for no gain. Fighting with white 56 is a way to make use of the strong white corner position.

Up to black 73, white’s result seems fine, having made the black left side flat in sente. White 74 is a huge move, both claiming the corner and preparing an attack on the upper-side black territory. White 80 is the said attack.

In hindsight, white 86 looks like bad shape for white. J16 instead fixes all white’s problems while still making sure that black needs to add another move to live. Up to 98, white’s shape mistake with 86 let both black groups live quite easily.

Black 99 appears to be an overplay, since white n18 is sente against the upper-side black group. It seems black should play o18 herself.

Black 105 is a fabulous placement stone, preparing for some trouble in the corner.

After black 115, the black corner group is not easily killable. On the other hand, since white got some stones towards the centre, it seems white holds the advantage anyway. However-

By white 120, the white shape is beginning to be problematic. I was too fixated on killing the corner group, which eventually lead to my losing the game.

At move 127, we see the reason for the black peep of h6 earlier, as the ladder starting from q9 works. This black can do some good reading!

For white 146, it seems that just capturing with o13 would be enough to win the game, as white would be able to get some territory in the centre.

White 154 goes the risky way. Turning with q6 instead was possible, as black wouldn’t have enough territory even with capturing the three white stones. The stones would be able to escape too, were it not for my misread later. I was in overtime at the time.

White 166 is the said mistake, practically wasting a white stone in the escape process. With o8 instead, it seems white will get out and respectively wins the game.

I actually continued the game some more even after losing the big chain of stones. I played until late yose, to the point when it became was clear that black was winning by about five points.

Today is Tuesday, which means another English class with the professionals! Last week we had a whopping 13 people present, which made it necessary to divide the class in two. It’ll be interesting to see how popular the class will get at this rate!

  1. What a nice game! There were also some direction of play elections by black that look odd to me, there’s probably a lot to learn from it… ^^

    BTW, as things stand now, Player number 1 and you are even with one loss, which is cool ^^. Good luck!
