;B[mo]CR[mo]C[danoontje [6d\]: The focus of the game is the on the lower side now. Black has taken a lot of potential territory on the left and right.]
;W[nn]SQ[mo][pp][mq][oq][pr]CR[nn]C[Black has used 17 minutes, White 12.

danoontje [6d\]: White is more tight and has more secure territory. So the deciding factor of the game will be how White invades Black's territory.

White doesnt want Black to have an easy escape with the marked group, so he prevents it with O6.]
;B[kq]CR[kq]C[danoontje [6d\]: L3 is a standard sacrifice technique. The idea is to sacrifice L3 to gain forcing moves on the outside, which will make Black's weak group stronger.]
;W[lq]CR[lq]
;B[lp]CR[lp]
;W[jq]CR[jq]C[danoontje [6d\]: White has to capture with K3 and Black gains L5 and possibly N2 forcing moves.]
;B[ko]CR[ko]
;W[kr]CR[kr]C[danoontje [6d\]: Normally K4 is better than L2, but White didn't want Black to get the N2 forcing move as well.]
;B[jp]CR[jp]
;W[ip]CR[ip]C[danoontje [6d\]: It would be too submissive to answer this at L3, so White resists with J4 instead.]
;B[jo]CR[jo]
;W[mr]CR[mr]C[danoontje [6d\]: This black shape is full of kos.

Answering N2 at O2 might seem natural, but would not be good in this case, I think, since the O4 weakness would remain; Black has a shape problem here. It's difficult to find a satisfying move.

BGAadmin [-\]: B is thinking a long time.

swine [5k\]: What move would you suggest here, danoontje?

danoontje [6d\]: I would probably want to tenuki... maybe escape with N7.]
;B[po]CR[po]
;W[qo]CR[qo]
;B[nr]CR[nr]C[danoontje [6d\]: Q5 protected the weakness at O4; now black can answer O5 if White plays O4. This was not possible before since White had the atari at P4.

swine [5k\]: So White will leave this for the time being?

danoontje [6d\]: Probably, yes.
]
;W[dn]CR[dn]
;B[dm]CR[dm]C[danoontje [6d\]: iInvading the left and right side seems to have high priority.

On the right side White has an invasion point at R13.

]
;W[en]CR[en]C[danoontje [6d\]: White strenghtens Black here with D6, probably because he wants an attack going on the M4 group.]
;B[io]CR[io]C[Black has used 29 minutes, White 20.

danoontje [6d\]: The left has invasion points at C12 and C15.

Somebody asked why R13 is better than Q13... R13 aims at making a living group on the right side, whereas Q13 only aims at reducing Black's territory.

In this position I prefer R13... after White R13, Black would play Q13 and gain thickness, but wouldn't be able to use the thickness because of the strong white position at the top.]

;B[co]CR[co]C[danoontje [6d\]: The lower left corner is a joseki.]
;W[bq]CR[bq]
;B[jd]CR[jd]C[danoontje [6d\]: The black group at the bottom is safe for now, so no need to escape with K8 for example.]
;W[ic]CR[ic]
;B[ld]CR[ld]C[danoontje [6d\]: I have no clue what Black wants with K16.

swine [5k\]: Making a moyo in the center?

danoontje [6d\]: Yes, that seems to be the idea.

swine [5k\]: Looks hard.]
;W[lc]CR[lc]
;B[md]CR[md]C[danoontje [6d\]: A white move around N8 would be logical to reduce the center and keep an eye on Black's bottom group, so a black move around N8 would make it look like a real moyo.

R6 is an idea for Black... if White answers with R7, Black cuts at P6 to increase the moyo. However, White can answer R6 at P6.]
;W[qg]CR[qg]C[danoontje [6d\]: Now Black has to decide if he wants points in the corner or outside thickness. A black move at R15 would secure the corner, and drive White to the center.

phenomene [1d?\]: It is tempting to take the corner and chase White into the center, considering Black's strength.]
;B[qe]CR[qe]C[Black has used 36 minutes, White 30.

swine [5k\]: Why did Black play at the top instead of protecting some invasion points?

phenomene [1d?\]: K16 and the following indirectly protect against the invasion; now White R13 will suffer.

inimino [8k\]: Now White will jump out into the center?

danoontje [6d\]: Yes, I think P13 now, although he might try R11 for a quick life.]
;W[qi]CR[qi]C[danoontje [6d\]: After R11 a big ko often follows. [See variation.\]

The idea is that if Black plays R10 now, White plays either Q12 or S10 to settle his group.

phenomene [1d?\]: Just jumping into the center was not so appealing; it would create a weak group with no black weakness to exploit... therefore, White wants to settle quickly.]

;W[bd]CR[bd]C[White has the right to establish a small group in this corner anyway.  Black can ignore this "ko threat" and let White establish a larger group in the corner instead.

Black has used 41 minutes and White 35.

phenomene [1d?\]: White makes a ko threat and a probe at once.

danoontje [6d\]: If White uses this kind of ko threat, then he has a lot of them, so Black probably won't answer.]
;B[oh]CR[oh]C[danoontje [6d\]: White is already dead on the right side. (If W retakes at R11, Black can atari at Q13.)]

;B[dh]CR[dh]
;W[ci]CR[ci]C[danoontje [6d\]: But after a move like N8, Black's center would be very big, so White should try to get sente, to play around O8.

phenomene [1d?\]: Now we see that the ko threat was not small, but I feel that Black has too much on the other side and might be ahead.]

;W[fj]CR[fj]C[inimino [8k\]: You mentioned R6 before... is there a good way for Black to cut off the O6 stone?

danoontje [6d\]: Maybe if he sacrifices the Q5 stones there is a way. But I think Black should leave O6 alone, as it would probably hurt his center more than he gains by capturing it.

BGAadmin [-\]: Black is counting.

danoontje [6d\]: OK, so we must count too.

White has: 25 points lower left, 12 points top, 10 points lower right, 10 points upper left. That makes 57 points + komi.

Black has: 8 points lower left, 4 points bottom and 40 points on the right... 52 points. That's without the center, which should be at least 10 points.

BGAadmin [-\]: B hs used 51 minutes, W 39

]
;B[gj]CR[gj]
;W[fl]CR[fl]C[danoontje [6d\]: Now the c6 group looks a bit weak, and needs reinforcement. After that, White should try to invade the center very deeply.

If Black plays B10 here and White answers at C13, then cutting points appear around E13.]
;B[cl]CR[cl]C[danoontje [6d\]: C8 is a proper move, defending all his weaknesses.

Now white should make a do or die invasion of the center. Something like M12, although it looks hopeless.

BGAadmin [-\]: White is staring somewhere near H12.

phenomene [1d?\]: I feel White has no good move available.]
;W[gi]CR[gi]C[I asked Mathew Macfayden what would have happened if White had played at B7.  He said that he would live his left side group at the expense of his E11 and F11 stones.  Because Black may need to sacrifice these two stones, he cannot commit himself to killing White's G11 cutting stone.

;B[hj]CR[hj]
;W[ij]CR[ij]C[Black has used 60 minutes, White 43.

danoontje [6d\]: Black is probably thinking whether he should cut at J11 or play H8.]
;B[hk]CR[hk]C[danoontje [6d\]: H9 is clever. This threatens F9, capturing the 2 white stones in a ladder.]
;W[em]CR[em]C[danoontje [6d\]: The left black group is a life and death problem... White has an annoying move at B7... I think Black dies if White plays there.

Now B10 would be a good move to defend against it.

Someone suggested e8 for Black to defend... I think it's a good idea.]
;B[hg]CR[hg]

swine [5k\]: But now what of the left side?

danoontje [6d\]: Maybe I misread... but I think Black is dead there if White plays first. [See variation.\]

DameZumari [1d\]: If Black can capture all the center, including all those white stones, it doesn't matter whether that black group lives....

swine [5k\]: What about D9 after White B10?

danoontje [6d\]: Right, moves like D8 and D9 are Black'ss sente, so Black probably lives.]PL[W]
(;B[je]CR[je]
;W[lf]CR[lf]C[danoontje [6d\]: I don't see why white goes in this direction... he should try to run in the direction of O6.

inimino [8k\]: Is there some cut he's going for with O16 or some desperate thing?

danoontje [6d\]: Yes, I'm sure that's what he aims at... O14 is White's sente now too.

]
;B[ng]CR[ng]C[danoontje [6d\]: It looks like White can live in the center... that would make the game close.]

;W[ll]CR[ll]C[This was the last move relayed to KGS.  The PC used for the relay crashed, finally and irreparably, at this point.

DameZumari [1d\]: White is not quite alive yet...

danoontje [6d\]: Making two eyes in the center (for instance with M11) and connecting with N7 seems to be miai.

Maybe we can count again:

White: lower left 25 points, upper left maybe 10, top 10, bottom also 10, center 5 points... that makes 65 points (including komi).

Black has 45 on the right side, maybe 9 points from L5 group, 8 from B5, 6 points from E14... that makes 68.

So it's a very close game.
