Robert Jasiek 5d beats Ali Jabarin 1p
Posted: Tue Aug 12, 2014 7:23 am
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.
