In my second game of the day I managed to get a resignation from my opponent after I made a decisive kill. After it was pointed out to me in analysis that my opponent could have made a ko for life by playing at o1, I didn't feel quite so smug about the kill. But if one's opponent doesn't see the ko, then the ko doesn't exist. I was euphoric from the kill and wanted to avoid the mistake of failing to take a break at the appropriate time. I went for a break to clear my head so I would not do something stupid in the aftermath of the kill. That has happened to me more than once. The second game of the day is shown below at the point of resignation. When I returned from my break my opponent resigned. I was really tired by then, and it was a relief not to have to play the end game. I am black.
My final result for the tournament was 4-1. That earned me a nice certificate suitable for framing, and a cash prize of $40.00, which paid for my playing fee and then some. As much as it would have been nice to go 5-0 I am glad things worked out the way they did. If I had not lost the 4th game I would not have had the valuable lesson about seki, which I am unlikely to forget. I also would not have been matched against my 5th opponent so I would have missed our game, which I found to be very interesting.
I do not expect my record to be sufficient to bring me up to 10k from 11k.
It is my plan to have Mr. Yang review the NJ Open games during our next lessons.
