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 rgg 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: W31: I think that there is enough aji left on the lower side to justify this as a dual-purpose move. If W can't effectively reduce the bottom after this, then it is probably too small at this point.
Bill: B 32: Another stolid, questionable play. ;-)
Dave W 21: Expanding the top Bill: B 22: Aye, aye, sir! Dave W 23: Action - reaction Bill: B 24: The flow of the stones. Dave: W 25: Trying to limit B's center potential while strengthening W's weak stones. Bill: B 26: Still flowing. Dave: W 27: I think the honte was 'a' but I couldn't bring myself to play it :-) Bill: B 28: "One space jump -- never bad." I hope. ;-) Dave: W29: Strengthening the left. Bill: B 30: High time, I think. :-) JamesA: Permit the intrusion of a much lower ranked player but isn't B30 a bad move? It doesn't really attack the 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 W 11: Heh, it's a handicap game so why not the traditional handicap-game joseki!?
Bill: B 12: I thought about 13 to make use of my stone on the bottom side. But on reflection I'll head towards tengen. ;-) Dave W 13 - W 17: Just following orders! Bill: B 18: Aye, aye, sir! ;-) Dave: W 19, I thought 'a' would be too aggressive with the diagonal B wall stretching up to tengen waiting for me. Bill: Another nice play, Dave! B 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 tenuki. ;-) Hmmm. It looks like I missed a trick. :-(
If I play B 1 instead 3, if now White plays in the other corner, B 3 works better than in the game, coordinating with both B 1 and the tengen stone. If W 2 makes a double kakari, I think I can manage to take sente and play in the other corner.
Dave W 5: I'll take the midpoint on the left, hoping that it will limit the effect of what you can do to W 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 B stone on tengen, I am hoping to avoid any really urgent fight as long as possible (rightly or wrongly :-)
Bill: Interesting play, Dave. :-) Dave W 7: Following 5 my theory is that I should be able to tenuki on the lower left, spending some of my komi to break up potential B frameworks.
Bill: Another excellent play, Dave. :-) Dave W 9: Sooner or later B'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 B in turn answered at 'c'. Bill: B 10, hane. If you play osae at d, I play atari at e. I am not sure if W 7 was the right idea or not. Dave
If W takes the right side and B takes the top then the approach move at 3 expands W's side while limiting B's top. This way W has superior influence in at least one part of the board. In the game, W'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 W 7 is good. :-) This is a copy of the living page "Game33" at Sensei's Library.
