Diag.: Ongoing game 2 (71-80)

DieterVerhofstadt: I think the 78-79 exchange loses liberties for white and patches a Black weakness, but then again maybe not. White is still behind territorially but has gotten thicker after Black backing off in the middle. White would love to play C but doesn't have the time. The shoulder hit seems to keep the attack going while making some use of the lone white stones. If I overexplain my moves, please say so.

Dnerra: After W 72 I started a discussion wondering why noone was volunteering to make the Black next move. HolIgor pointed out that Black is leading, but that White still has chances. Maybe DieterVerhofstadt will change sides and play Black from here on. Since I've waited a couple of days, I played B 73 now.

HolIgor: I've waited 3 days and played though I was the author of the latest move. We are closer to a fight and then people will have more interest than at this stage of slow preparation.

Dnerra: I thought this is a fight already! :-) Both sides have to be aware of the cut at a at anytime.

deft: I made a move...

Dieter: ... and I responded (sorry dnerra). I know one should not peep where one can cut, but I think one can't cut here. White is vulnerable to a move at B. White 76 is the shape point for both running groups, so I think it is the only move here.



BillSpight: B 69 was enterprising, but B 71 is on the undynamic side.

dnerra: As I made both black moves that you are referring to :-), (hope this isn't consiedered inappropriate here to play two consecutive moves) I would be very interested if you could elaborate. I felt that because of the marked white stone, B will not be able to profit too much from influence built up around B69/W70. Also I didn't see a move that would hurt whites shape around W70. Also, I would not have liked to play a move like B a, which would neither seriously attack the white dragon, nor remove the potential of W68. So I decided to take profit, and let white prove that she can gain from attacking my group. What is your suggestion instead of B71?


Bill: B 71 is inconsistent with B 69. B 69 provoked W 70, hardly a surprise. :-) B 69 aims at a fight in the center and bottom side. If all goes perfectly, Black will be able to strengthen his central group, put pressure on White's single stone on the bottom, build a wall that makes it difficult for White to do much with his stone in the right bottom corner, and cut on top, putting pressure on White's cut groups. OC, White will not allow that to happen. ;-)
But B 71 gives up on all that, except securing the bottom right corner. It is now easy for White to throw away his stone there, building thickness that works with the White stone on the bottom, protects White's central group, and weakens Black's central group. Provoking W 70 helped him do that. B 71 is an admission that B 69 was wrong.
Right or wrong, Black needs to forge ahead with the hane at 74.
(This is not to say that B 69 was the best play. But it shows an admirable fighting spirit that B 71 lacks. :-))

Diag.: Ongoing game 2 (61 - 70)

DaveSigaty: 70 I agree that the urgent question is who is strong and who is weak in the center and top. W wants to keep pressure on the center B stones. Can B swallow the lower right despite the aji of 'c' and 'd'? Need B fear the weakness at 'b'?

dnerra: I can't resist the temptation to choose the sharpest (I believe) move. Of course, B 69 aims at the peep and hopes for a successful cut around a in the future.

HolIgor: W68. I made a previous move for white so I've waited a while before making this move. Nobody else volonteered. There are too many urgent points for white at the board at the moment. I believe that white is about 20 points behind now and something has to be undertaken. White has to use the her bits of influence. Unfortunately I could not find sente sequence in the top right corner.

TakeNGive (11k): For B#65 - looks like Black has to choose. Save 3 stones and try to live small on the side? Then White will chase the top center eyeless stones. Instead, give up three useless stones, and connect the right side to the top center (say around P16)? Or, tenuki in favor of something like C7?

HolIgor 52: I'd like white to keep thick and solid.

BillSpight 54: If B 37 (marked) had been at a, W 54 would not threaten two cuts.

DaveSigaty 58: thinking of 'a' and 'b' as miai.

Diag.: Ongoing game 2 (41 - 50)

MortenPahle - the question is whether there's anything left to strike once the fist is made ;^)

BillSpight: B 41 looks better at 50, eh?
Then W 40 doesn't look so big. MortenPahle - In fact, B41 looks rather rediculous at present :-(

HolIgor 42: Black has taken the corner. It is an established fact. White's intention is to either limit black in sente or have a furikawari. I wonder why black did not play at '3' at move 39 instead?

DieterVerhofstadt: Yes. IF I would play in that area, I'd indeed played at '3'. The keima leaves a weakness.

MortenPahle: Hmm. This can get tricky. Black 39 may turn out to have been greedy.

DieterVerhofstadt: Thin, not greedy.

Bill: It looks like B 45 will end up with gote. Maybe it would be worth it to play at 48 and take sente.

MortenPahle: I don't understand your comment, Bill. Can you elaborate?

Holigor 46: I thought that white should not determine the position at this move and try to keep a little ahead of black. (--Dieter: you're probably right. I thought this way there would be more aji.)

MortenPahle: At the end of this sequence I am not sure how to continue - I have the feeling that white has thwarted my original intentions, but I take the risk of putting my head on the block and continue what I started .... Just for my continuous improvement, can one of you give me an example of what could have happened if black 39 at 43?

I'll give it a try at Ongoing Game Two Move Thirty Nine Discussed. Sooner or later we will have to WikiMasterEdit this thread as we did with the Ongoing Game.

BillSpight 34: Trying to play lightly.

unkx80 33: Because white can play at 34, I guess black 33 might be better off playing at either 34 or 37?

BillSpight: We seem to have stalled, and at a very interesting point, too. ;-) Too much kibitzing? I would find that inhibiting, even though I would be glad for later discussion.

White fell behind early on, but the center fight offers possibilities. :-)

HolIgor: It seems that black resigned.

MortenPahle 37: Why not?

BillSpight: B 37 at 'a' is also a thought.

MortenPahle 39: Make a fist before striking :-)

HolIgor 40: Aye, aye, sir.
