Hi. I'm a beginner in Cambridge, UK, recently migrated from chess. E-mail: <cjb@mrao.cam.ac.uk>, Web: <[ext] http://www.mrao.cam.ac.uk/~cjb/>.


I came across this pattern in a game today (2004-03-01). I proceeded to start playing like my normal patzer self soon afterwards, losing b5-c5 after the cut on d5, and letting all of the white groups live. Are any of them ``technically'' dead, though?

Thanks for reading.

Black to play -- who lives?

The first thing that came to my mind

Quacki : The monkey jump at B1 would kill the left white corner group. The stones with circle are basically alive (A white hane at W2, answered by B3 reduces the space to four in a row, which is alive). I did not read out (if possible to me) B1. There may the possibility that white can cut and kill one of the two squared groups.



(2004-04-14): I came across this seki in a game today; unusual since black has no eyes and white has two, rather than them sharing the same number. I was playing black, and white resigned at this point -- perhaps seeing that he couldn't play anywhere without checking to see whether it was the case that I couldn't either. :-) Does anyone else have unusual sekis to show off?
