Hi everyone!

This is Game 9; one to go! :)

This game is dedicated to *dmitri*, who in real life is my roommate.  He was
probably the only unbeaten player in IGSWCT'92 (he won a game and dropped
off :-).  Well, he didn't drop off to keep this "unbeaten record"; rather,
he was very busy.  He has been working very hard on his violin.  He works
so hard on violin that I would be ashamed if I don't work hard on Go. :) Of
course, violin will be his profession, while Go will not be my profession.
:(

Go is my life.

jzy NR ^_^

P.S. If I am lucky then I will be able to post Game 10 sometime next week;
otherwise, wait till next month -- I could lose contact with net, thus IGS,
(temporarily) for a month.  But, according to the sky... :-)

Comment[From modern point of view, W P14 to exchange with B N17 is a disadvantageous move territory-wise.  But ancient players liked P14 since now P9 would be a good point for W.]

Comment[Apparently, both sides think that P9 is important.]
Black[ok]
;
Comment[Powerful.  It covers B's corner; at the same time connects with his own stones, thus isolating B J17 stone.  Therefore, looking back, B R12 was questionable.  It should be at N15, and when W P9, B Q11.]
White[md]
;
Comment[No choice.  O16 would be a common method for B, but that would hurt J17 stone even more.]
Black[nc]
;
White[ld]
;
Black[qe]
;
White[rf]
;
Comment[If O15 is skipped, W would have S17 to squeeze B corner, and B J17 stone would be swallowed.  Still O15 is somewhat awkward, although it's B R12's fault.]

Comment[W Q10 first then O10 and N9 are good moves that take care of both offense and defense.  Without O10 and N9, B could play Q15.  Although W S11 would be a good move in this case, B R11 would force W to play S12 and B would become very thick.  But now with O10, when B R11, W could play R10 cut.]
White[mk]

Black[lj]
;
White[ii]
;
Comment[B is hoping W to connect at K11, then W could prevent W L9 with sente.]
Black[jj]
;
Comment[W sees B's plan.  Now if B L13, W J12 and B's escaping path would be narrow.]
White[kh]

Comment[W can't play G13 but has to play J16 to capture B stone.  Painful.]
White[id]
;
Comment[Powerful.  To W, this is J13's fault.]
Black[gg]
;
Comment[Too strong.  Should be at H11 to "wait and see," and W would still be leading.]

Comment[Strong move.]

Comment[To here, B determinedly gives up nine stones.  Although that's a 30-point loss, but B manages to relieve a heavy burden, gaining a remarkable outside potential.  Plus B has the sente.  B is now in a much better shape.]
Black[ef]
;
White[fd]
;
Comment[Severe.]
Black[qq]
;
Comment[Normally, facing a strong potential that B has now, W Q3 would play R4 \(followed by, B first, Q3, P4, P3, and P6\) to try to live.  But one, this \(R4 etc.\) probably wouldn't fit the ancient style; two, W must not be optimistic about his game, so he decides to risk and cut B apart.]

Comment[Can B N5 \(instead of K4\) to cut? The variation here is extremely complicated \(Editor: sorry I am skipping these variations again *giggle*\) and the result is not in favor of B.]
Black[jp]
;
White[jn]
;
Comment[Again it's not a good time for B to play N5.]
Black[in]
;
White[im]

Comment[L6 here seems to be a better move for B.  B H6 intends to give the whole W group an attack, but it's not as tight as L6 would be.]

White[jm]
;
Comment[Seems to be a miscalculation by B.  But in fact it's a hard-thought, deep move.  L6 deprives a possible eye at L5 for W, and it also prevents W from skipping a move here to play D2.  However, W now has M2, but that won't deny the fact that a move at L6 first is better than B M8 directly.]

Black[ls]
;
Comment[Good.]
White[mr]
;
Comment[If B plays O2 instead, W L4 is sente.  Then when B K3, W N1 to get three B stones.  Or, when W L4 cut, B plays N1 instead, then W K3 to cut down B group and kill it.

Now B turn to play E2 to attack W team.  This is probably the last fight for B; that is, if W lives here, B's territory won't be enough.]
Black[er]

White[fn]
;
Comment[Prevents W D3.]
Black[ep]
;
White[fp]
;
Comment[Necessary.  If B E8 directly, W can live.]
Black[go]
;
White[fo]
;
Black[el]
;
Comment[Seems to be incomprehensible.  Normally W D6, but then B B5 is a good move and W can't escape.  After thoughout study, W C5 is found to be an most extraordinary move.  With this move, W team is out of danger.]
White[co]
;
Comment[B certainly wants to play D6, but after \(W first\) D5, E5, E6, C4, D7 and C6, W has F8.]

Comment[No choice.  If B tries to damage W's eyeshape here, W plays D2 and B later might have to live the corner with a ko -- and W would then have no problem to live by playing this ko.]

Comment[K3 and K2 are the only way to live.]

Comment[White wins by 4.5 zi \(9 pts\).

Overview: Both sides had questionable moves, but there were quite a few good moves as well.  For example, W #51, #53, and B #74 etc.  Especially W #131!  If I \(Chen 9p, not the editor :-\) can learn just this move, I would be greatly satisfied.]
