C[This game was played on Sunday 23 October 2005 in Meadowridge, Cape Town between myself (Konrad Scheffler 1d) and Aketa Katsuyuki 6d. Comments are mine except where indicated.

(;B[kp];W[or]
C[Seems slow, but white is undermining black's shape. This is consistent with Aketa-sensei's slow and deliberate style. According to Ishida's joseki dictionary, white should play at Q6 or tenuki instead.
]
(;B[mq]C[This is the correct way to make strong shape.
];W[iq];B[gq];
W[io]
(;B[dj]
C[This sort of tenuki is often a reasonable practical choice in handicap go, but is not as severe as a local continuation.
]
;W[go]
(;B[fp]C[Not good shape.

(;B[nn]C[Too submissive. Now black gets into some trouble.
];W[nk]
C[Nice shape. Black has difficulty moving out whichever direction he chooses.

C[Unfortunately this standard cutting idea needs a stone at N7 to work properly.
]
;W[lj];B[mk];W[mj];B[kj];W[jk]
(;B[ml]
C[Upset about my misread, I compounded it with another one. Only the bamboo joint at N7 would fix black's defect. White would be in no trouble, but saving the cutting stones is probably worth it.


]
;W[nl]
C[Black has gained nothing from the exchange, and playing at N7 now would seem downright silly by comparison. Still, keeping the white groups separated must be big.
]
;B[pl]
C[Giving up in disgust, but this is not properly connected and all the white stones now become strong.
]
;W[mm];B[ln];W[ll];B[jn]
C[Probably another bad move. If black wants to solidify the group, around K2 is probably better. The move played just ends in gote and does not exactly clarify the status of the group.

;W[eh];B[fh];W[fg];B[eg];W[bh];B[bf];W[ck];B[cj];W[bj];B[gh]
C[Aketa-sensei seemed unhappy on seeing this move. He has the option of cutting at F11, but black doesn't mind sacrificing a few stones.

B[fc];W[ig]
C[This re-activates the cut at F11, but that is now way too small - having made a heavy group white is obliged to try and save it.
]
;B[jg];W[ih];B[ii];W[jh]
C[I don't know why Aketa-sensei made the last two moves. He was tired, but is it possible he misread the ladder?

;B[kh];W[jc];B[kc];W[kd];B[lc];W[ic];B[ji]
C[I was happy to whip off these stones - now the entire position is solid.
]
;W[dc]
C[Aketa-sensei has a habit of muttering under his breath - somewhere around here I thought I heard him say "hamete" (trick move) but I wasn't sure...

C[This makes an eye, but I still couldn't see where the second was going to come from.
]
;B[hb];W[gb]C[Of course! After this tesuji white lives in ko.
];B[gc];
W[hc]
(;B[fb];W[ib];B[ga];W[kb];B[lb];W[ja]
C[White has miraculously created life in ko, but in the process black has taken a large corner, solidified the center stones and built a huge moyo in the upper right. Even with unconditional life this would still be bad for white.

I'm not in a particular hurry to start this ko, as I would have to come up with the first ko threat and stand to lose something if I lose the ko. So just continuing the game seems a simpler way to win - if white wants to take time out to secure his life, black is happy to get 2 moves elsewhere.
]
(;B[pf];W[kr]
C[White's last attempt to pull a rabbit out of the hat - he must drum up an attack against black's group.
]
;B[qj]
C[But this is a large move, making miai of connecting out and living with a move like M2.
]
;W[nr];B[qm]
C[This connects out safely, taking territory at the same time. Looking at the whole board, black is ahead even without counting any territory from the moyo at the top right or the profit to be had from the ko. White resigns.

(;B[la];W[ka];B[cf]
C[Preparatory moves necessary to remove white's internal ko threats.

(;W[qp];B[ia];W[kr]
C[Is this a ko threat? I couldn't be sure what the cost of winning the ko would be.
])

(;W[gb]
C[The threat is too big to ignore, but just for illustrative purposes...
]
;B[qp];W[db]
C[If white wins the ko he starts another, for a substantial amount of profit. So black should only start the ko if he knows he will win it.

C[Afterwards Aketa-sensei showed that this would have been much better.
]
(;B[ec];W[eb];B[ed];W[fb]
C[If black blocks on the outside, it's not so easy to find a good continuation. If black now tries too hard to capture the F13 stone, the capture will be small and white will be more than satisfied.
])

(;B[cc];W[ec];B[cb]
C[But if black takes the corner white will have a much easier time settling the stone at F13 compared to the game.

C[Again a local continuation is better. Aketa-sensei suggested this point.

(;B[eq]
C[Andrew pointed out (and Aketa-sensei agreed) that this would be better, aiming at the double peep at H4 (note the bad shape for black if he tries this after the game continuation) and strengthening the corner more.
])
)

(;B[go]
C[Aketa-sensei recommended this move, putting maximum pressure on the white stones and strengthening the corner.
])

(;B[hp];W[ip]
C[On being asked about this peep, which would prevent the white cap at G5, Aketa-sensei insisted that the exchange is bad for black - weakening the black group to the right like this is too high a price to pay.
])
)

(;B[nr]
C[This territorial move may be appropriate at a later stage of the game, but it leaves aji which white can exploit with e.g. a clamp at N2 or a peep at N3. Generally not recommended early on when black should be more concerned with shape than territory.
])
)

(;B[on]
C[Despite the move played being joseki, Aketa-sensei recommended this move instead. Black is playing on a larger scale, and the thickness created will work optimally with the handicap stones.

;W[po];B[oo];W[or];B[mq];W[pm]
C[This is a possible continuation (joseki).
