UK Tie with Germany

Pandanet Go European Team Championship
Pandanet
12 December 2017

The fourth round of the B-League on 12th December saw the UK playing one of the other teams on three wins, Germany. After some exciting games the match ended a draw. This left UK just above Germany on boards won, but Netherlands were expected to beat Turkey and take the number one spot in the league table.

This was supposed to be my toughest test so far, so while maths has been prioritised this term, I tried to study go for the last 2 weeks, particularly define 3.0 on the computer Go server.

He opened adventurously with four 11-3s. Especially as I wanted to play territorially anyway, this set bells ringing in my head that this should be a territorial game (hard to make frameworks, so I focused on the corners). He invaded 3-3 into my star point and his result was poor when I took the corner (the 10-3 was an inefficient one space extension from a ponnuki). He attached star point on my komoku, I took the corner and I was happy. He attached 3-3 on my other komoku, and I was very happy to take a very large corner.

He finally invaded 3-3 into my other star point, I played good direction, but overlooked a severe cut, when he blatantly had more ko threats. However, instead of ending the ko to get a good result, he made the ko even bigger. He played a poor ko threat worth around 25 points. Ending the ko, I got a massive corner territory plus thick influence, and he had a wasted stone on the outside.

Furthermore, he overlooked a lovely tesuji I had for liberties in the semeai, and a horrific bulky 6 tesuji, so even his follow up to his ko threat died on a large scale. So by move 90, I already had 80 solid territory points compared to his 20 or so. He had to place his hopes on the centre.

I decided I still wanted an interesting game, and played daringly into the centre, but a peep overplay and a big blunder on the upper left, meant my group in the centre wasn’t clearly alive. However, his position was just too thin and eventually I captured another 50 point group with my centre group.

Unfortunately I then realised I had 2 seconds to play 2 moves. So I was frantically power-clicking S19, a move worth around 200 points just in case he ataried it. I wouldn’t mind if he got three moves elsewhere, as long I could play S19 (and maybe S18 to fill my own territory) and get into the next time period. He tortured me for 7 minutes like this! But he honourably resigned. I could have cried in relief.

In the middle game we both had unsettled running groups and I think it was fairly even. At some point though white’s group got out into the centre while consolidating white’s centre potential into points.

At this point I was badly behind so I tried cutting off one of white’s groups towards the top side. Benjamin played a forcing move that wasn’t really forcing which allowed me to completely cut off his group. It was a semeai where I had an eye and he didn’t so I really thought I would win it (and it seems so did everyone watching), but my group got squeezed a lot and it turned into a massive seki. I was far behind on points on so I resigned.

Looking at the capturing race now it’s not clear what I should have done so maybe it wasn’t as simple as I thought. I’ll take a proper look tomorrow.

The opening seemed to be in reasonable balance, though my opponent's position became very thick. I went wrong in the middle game by allowing a group to become too weak, and ended up making an unfavourable trade for it. I found a nice tesuji later on which prompted a large trade, but this again created a weak group that was hard to manage. Later on I tried to capitalise on some bad aji, but this did not pan out and I was left with no way to catch up.

Chris Bryant wrote: I won my game against Michael Palant by resignation. I played quite a fast opening, ended up with a good presence in all four corners in exchange for tenukiing a couple of his moves, and in return he got quite a large moyo, but it was a bit undercut on one of the edges. He invaded quite deeply into my area and ended up making two weak groups next to each other. He played a move on one of them that felt a bit slack, so I attacked the other, figuring I'd get enough strength to try to kill the one he played the slack move on.

He ended up actually letting me totally surround the group I attacked though, instead of defending himself. He chose two outside moves (the first of which I think is a super nice tesuji, the second of which I think is really greedy) instead of connecting himself out. So I cut him off, and then he scrambled around realising that he didn't have enough space to live in. He got a semeai against my cutting group but realistically I had a lot of space to run into, and ended up winning when he let me capture another few of his stones in the centre.
