Three-stone free placement handicap for Black versus 35.5 Komi for WhiteThe game below resulted from the discussions about teaching game 53 where Black is receiving a large reverse komi in addition to two handicap stones. Enjoy!
Dave: 35.5 seems fine for the first try. More generally, what is the procedure to bid between two players to decide komi? I remember reading a discussion of it on rec.games.go but can't remember how it should work.
Bill: There are a few schemes. I like sealed bids. High bid wins and takes Black. If the bids are the same, use nigiri or flip a coin. Komi is the average of the two bids, rounded up to the nearest 1/2. If the bids are different, each player gets a subjective advantage. :-)
SAS: This last system is (or at least was) used in Japan's Strongest Amateur tournament. See Latest Move Marked
Dave: White 41: So much for the corner!
Dave: White 31: I think that there is enough aji left on the lower side to justify this as a dual-purpose move. If White can't effectively reduce the bottom after this, then it is probably too small at this point. Bill: Black 32: Another stolid, questionable play. ;-) Dave: White 33: The last tidying up before the fighting begins? Bill: Black 34: Aye, aye, sir!
Bill: Black 36: A kikashi before dying. ;-) Dave: White 37: Win or lose, answering 36 seems unbearable. But at the same time, I can't actually tell whether 36 is an effective kikashi or not if I do answer. The bottom is too complicated and I can't read out what would follow. Therefore I follow the age-old amateur proverb, "When in doubt, tenuki!" :-) Bill: Black 38: Do or die! (Maybe both, eh? ;-)) Dave: White 39: We will just have to see where this takes us! Was the analysis for 37 Katteyomi?
Bill: Black 40: That's my kind of yomi. ;-)
Dave White 21: Expanding the top Bill: Black 22: Aye, aye, sir! Dave: White 23: Action - reaction. Bill: Black 24: The flow of the stones. Dave: White 25: Trying to limit Black's center potential while strengthening White's weak stones.
Bill: Black 26: Still flowing. Dave: White 27: I think the honte was a but I couldn't bring myself to play it :-) Bill: Black 28: "One space jump -- never bad." I hope. ;-) Dave: White 29: Strengthening the left. Bill: Black 30: High time, I think. :-) JamesA: Permit the intrusion of a much lower-ranked player but isn't Black 30 a bad move? It doesn't really attack White's left side group and doesn't secure territory. Also, Black is very strong on the bottom side. Isn't the top left more urgent? (or the bottom right bigger?)
Dave White 11: Heh, it's a handicap game so why not the traditional handicap-game joseki!?
Bill: Black 12: I thought about 13 to make use of my stone on the bottom side. But on reflection I'll head towards tengen. ;-) Dave White 13 - White 17: Just following orders! Bill: Black 18: Aye, aye, sir! ;-) Dave: White 19, I thought a would be too aggressive with the diagonal black wall stretching up to tengen waiting for me. Bill: Another nice play, Dave! Black 20: Stolid play?
Bill Spight: I've been kibitzing a lot lately. Now you can see how badly I really play. ;-) Dave, if you start in one open corner, I'll take the hoshi in the opposite corner. Onegai shimasu. <bow> Dave Onegai shimasu. As you so kindly reminded me, the open corners are miai :-) Bill: I thought about a, but maybe 2 makes better use of the tengen stone. Dave: With 2 the lower right seems to become more urgent than the upper left. Bill: You're a smart man, Dave. :-) If you weren't so smart I'd try 6, but I am afraid that you'd play tenuki. ;-) Hmmm. It looks like I missed a trick. :-(
If I play Black 1 instead at 3, if now White plays in the other corner, Black 3 works better than in the game, coordinating with both Black 1 and the tengen stone. If White 2 makes a double kakari, I think I can manage to take sente and play in the other corner.
Dave White 5: I'll take the midpoint on the left, hoping that it will limit the effect of what you can do to White 1. I also considered the alternative of playing at the top and letting you take the left. This seemed to make it more urgent to continue with the lower left. With the black stone on tengen, I am hoping to avoid any really urgent fight as long as possible (rightly or wrongly :-)
Bill: Interesting play, Dave. :-) Dave White 7: Following 5 my theory is that I should be able to play tenuki from the lower left, spending some of my komi to break up potential black frameworks.
Bill: Another excellent play, Dave. :-) Dave White 9: Sooner or later Black's handicap starts to exert its force. I first planned to answer 8 with a play at b but was afraid of what would happen if Black in turn answered at c. Bill: Black 10, hane. If you play osae at d, I play atari at e. I am not sure if White 7 was the right idea or not. Dave
If White takes the right side and Black takes the top then the approach move at 3 expands White's side while limiting Black's top. This way White has superior influence in at least one part of the board. In the game, White's stones are more scattered and it will be a delicate problem to avoid being attacked too strongly. Bill: Maybe so, but allowing the sanrensei is easy on Black, and it works with the tengen stone. I still think White 7 is good. :-) Path: HandicapGoPath · Prev: TeachingGame361 · Next: BQM30 Path: CommentedGames · Prev: TeachingGame361 · Next: AlterPedroTeachingGame This is a copy of the living page "Game33" at Sensei's Library. ![]() |
