Robert Jasiek 5d beats Ali Jabarin 1p

[RobertJasiek]

The exchanges 34-40, 60-69, 76-82 and 84-88, in which White shifted the territory balance in his favour and let Black get the favourable influence balance, made me happy. 89-91 followed by 96-101 was my plan. With 69, I was prepared to sacrifice the stones 23 and 65; White 112-120 and White 133 fulfilled my wish. In between, I could take the huge reverse sente 127.

Especially moves 47, 50, 51, 112 and 120 deserve further study of variations. With 50-52, White decided to counter the black center influence. With 60, 76 and 84, White must have thought that the black center would not become too great. In my opinion, White 70 was too slow; there was no severe double attack on the adjacent black thick shape groups. In particular, moves 145 and 162 seem to be small endgame mistakes not affecting the winner. Black 181 has a nice timing because White must not try to start exchanges at that moment.

After surviving the opening starting from one of my favourite patterns, the game was won due to superior positional judgement. At the moves 77, 83 (anticipating 84), 87 (anticipating 88-91), 91 (anticipating something like 92-101), 103 (not giving way too much), 113 (allowing White 136), 127, 133 (giving way to restrict the aji), 153-165 (not giving way a bit), 175-177 (allowing White the reverse sente 178) and 185, I was confident to win the game by about 2 points. Maybe Ali expected me to play 109 at N11 followed by a ponnuki or other good reduction shape, or to connect at J3 with 113 and then reduce my center? White 70 or 84 would have been better chances for reduction of the upper center.

In conclusion, my first even game victory against a professionally ranked player was well deserved. As far as I know, it was Ali's first loss as a professional against a European amateur-ranked player in non-Blitz, non-Rapid tournaments. This is such a nice aspect of European tournament go: there are even games regardless of amateur or professional ranks, and the professionals have the courage to accept occasional losses.

Don't tell me you have created another set of rules.

Congrats RJ

[emeraldemon]

Congratulations on the win. What do you like about the 5-4 3-4 opening?

[oren]

This is such a nice aspect of European tournament go: there are even games regardless of amateur or professional ranks, and the professionals have the courage to accept occasional losses.

Congrats on the game, but I want to point out that there are open tournaments in the US and Asia as well.

[John Fairbairn]

I thought RJ's play was definitely superior, and his consistent strategy was especially admirable, but I found it hard to see anything in JA's play that smacked of professional level. Does anyone know how a 1-dan European pro is meant to stack up against, say, a "proper" Korean 1-dan pro (three stones handicap looks plausible to me).

[Uberdude]

A 1 dan European is not a set strength, but a title awarded to the top 2 in the recent qualification tournament. Ali's European Go Rating, which I think is a pretty reliable indicator of strength, was 2658 (before it got reset to 2700 the 1p level, a decision which seems somewhat strange to me, but consistent with resets of other pros like Catalin or Diana based on pro promotion rather than earning points in European rated games). In the Lee Sedol vs the West series the West of Catalin (2696 GoR), Andy Liu and Gansheng Shi who are all a bit stronger than Ali (maybe half to one stone?) got pushed down to 3 handicaps when it was abandoned. But Lee Sedol is a top pro not a 1 dan pro. But then some new Korean pros are pretty close to top level (thinking of Shin Minjoon for example http://gogameguru.com/prodigies-upset-t ... -go-games/). Korean ex-insei like Hwang In-Seong who are close to but not quite (new Korean) pro level are 2800 GoR. So I would say 2 stones certainly, 3 maybe favours Ali a bit? And certainly less than 3 stones from an old low-dan Japanese pro I think.

[RBerenguel]

Congrats Robert, good work.

[RobertJasiek]

I like the 5-4, 3-4 opening as Black because a) it involves an influence stone and I like playing with influence, b) it allows a large scale pincer if White makes a standard approach to the 3-4 and I like using such pincers, c) the two opening stones can be combined well with splitting the lower side for most of the reasonable white combinations of White's first corner stones and I like this splitting because I am a destructive player WRT to opposing moyos (I prefer to prevent moyos before I need to reduce or invade them deeply), d) the previous features lead to follow-up openings I am experienced with and for which my winning percentage is above what it would be for many other standard openings.

[Bill Spight]

Cher Robert,

Congratulations! Well done.

You got the last big play of the opening, and then built up a commanding lead by move 101.

[oca]

Congratulation now, back to my so much to learn...

[logan]

Congratulations Robert.

I remember when Uberdude beat Breakfast, so maybe you two should play each other now

[lemmata]

The thrill of beating a much younger player at the top of his game has got be great. It's certainly very inspiring for those of us in the over-30 crowd.

Congrats.

[Joaz Banbeck]

Nice win.

But I keep wondering why 127 wasn't at J3...

or 122?
