2007-04-25: I played this magnificent B-2 bomber in a three-stone game last night. :) It's black to play.
2006-03-19: An awesome life and death problem from a KGS game, http://kgs.kiseido.com/games/2006/3/19/flyingo-twoeye-3.sgf . The question is the status of the bottom-middle black group, if W plays first. I like this problem because it took me three different conclusions of why one player was alive before I got to the correct one. :)
2005-12-06: A silly page wondering whether I've acquired the UltimateGoBoard.
2005-11-11: A beautiful (but sadly unplayed) squeeze from one of TheCaptain's games tonight; white to play. W resigned, missing that L8 (circled) captures B, and keeps W's otherwise-dead group connected no matter what the B response. Check it out! http://kgs.kiseido.com/games/2005/11/11/Rumburak-TheCaptain-2.sgf
2005-08-28: I'm going to mention some patterns I'm trying to see more often, since they tend to improve my games. Here's the first; black overplays the response to white's cap, and plays himself into a ladder.
2005-07-01: I thought I'd start putting some favourite games from KGS up here:
- macisajt(8d) vs. Kosai, 2005-06-27: My first (and possibly last ;) time playing an 8d! It followed the usual nine-stone pattern of being ahead until early endgame, and then losing everything; I was down to 10s/move at the end.
- Kosai vs. rs220675(10k), 2005-06-29: I'm really happy with the willpower we both showed in the centre fighting, and really unhappy with my fuseki. Comments on both appreciated!
2005-07-01: My rank graph at the BGA.
2004-09-09: I wrote a piece of software for interpreting photographs of Go boards and outputting an SGF of the state of the board. Lots of images and a movie at < http://www.inference.phy.cam.ac.uk/cjb/image2sgf.html>. Feedback appreciated!
2004-07-12: http://www.queena.com/clips/go.html is a great article.
2004-07-04: A small progress table. I've been playing on KGS for a few months now; my username there is Kosai.
Date Rank Time/kyu 2004-05-01: 20k? One week. 2004-05-20: 18k Two weeks. 2004-06-01: 17k Two weeks. 2004-06-20: 16k Two weeks. 2004-07-01: 15k Two weeks. 2004-07-20: 14k One month. 2004-08-20: 13k One month. 2004-09-20: 12k One month. 2004-10-20: 11k One month (predicted).
Here's hoping I can make SDK before Christmas.
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.
Quacki : The monkey jump at would kill the left white corner group. The stones with circle are basically alive (A white hane at , answered by reduces the space to four in a row, which is alive). I did not read out (if possible to me) . There may the possibility that white can cut and kill one of the two squared groups.
Velirun: The corner will just wither away and die on its own - no provocation necessary. Next, you can aim at an invasion on the top. Either 3-3, a jump along the left side, or using the two cutting points top right will yield a fine result. Here's what may happen lower left:
Velirun: Poor corner...
(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?
I don't know if you're still working on image2sgf, but I think GoCam might be interesting, since the program seems to recognise the grid from the image.
