Organization: University of Helsinki

Hi everybody!

Here is a new game for you all.  Again I appreciate reports of
mis-arrival and such.  Suggestions/comments/questions are welcome. 

Most people reading this should know that there are other games
commented by me at the go archive.  If anyone has need for more info,
has problems, or does not have ftp, I can try and help, eg. by mailing
the games or something. 

For a change I felt like commenting a bit more thoroughly, and felt like
testing a few programs besides.  This file is in a brand new format,
although in one that should display in mgt as if nothing had changed. 
About other programs, Smart Go for example, I don't know.  I have had a
report that letters don't show on Smart Go Board, but there's nothing I
can do to that.  Letters are just too good a tool to leave unused.

Besides being in mgt short format, the lines have been cut to a maximum
of 79 chars, a fact that should ensure everybody receiving a faultless
copy, even besides the obvious advantages of shortening the file a bit. 

OK, enough blabbering.  This is a game between John Bate, 2 kyu, and
Tero Sand, 2 kyu.  An even game (I was requested this, too), with
multiple commentary, as both the players precommented, and I added my
commentary to that. 

It's interesting to see how both the players suffered of (what seems to
a lowly 3 dan) misconceptions.  And the same ones, even. 

This time I have to thank Adrian Marino for sending me a line splitter
(even if I had to fix it a bit :-).  Those of you with newsreaders or
mailers with 80 char line limit will be sure to appreciate. 

Enjoy.

	Olli, 3 dan

 Comments by TS, JB and
 Olli Lounela, 3 dan.];W[dp];B[pq];W[po]L[qk]C[JB: I like to play the high 
kakari here before Black plays around "a".

OL: Moyophobia, eh?];B[np]L[pl][qo]C[TS: 'a' might be better, after all. I 
was just tired of seeing it all the time.   

JB: Most people seem to play "b", leading to a similar result to the move 
played.

OL: All three are probably acceptable although the actual move feels a little 
slack, as if black were lazy.];W[qq];B[qr];W[qp];B[or];W[qk]C[TS: This, as 
Kajiware puts it, kicks Q16 in the teeth.

OL: That's what he says all right, but even the professionals disagree about 
it... :-\)];B[cd];W[ed]C[JB: Same idea again.];B[df]L[hd][gc]C[TS: I figured 
Q16 had already lost its main power, so I thought getting sente is best.

JB: I would think that playing something like "a" would be better to try to 
keep the star-point stone happy in at least one direction.

OL: Well, this is not a simple matter. Naturally 'a' is worth considering, 
and 'b' is actually modern style.

However, I feel that creating a symmetric position lacks in fighting spirit, 
makes the game too simple.

I'd probably play 'b'.];W[cc];B[bc];W[dc];B[be];W[ic]C[JB: Now the star-point 
does look fairly constricted.

OL: This situation is not to black's liking. The invasion at 'a' is just too 
easy to do, and there are no good moves for black in the top right corner.

Whereas no real mistaeks have been made, still white seems to have taken the 
lead.]L[qc];B[on];W[oo]L[pn][qm]C[JB: The idea was to make the next move 
\("a"\) sente.

OL: That does not make it a good move. This move just strengthens black.

The normal way is to play 'b' and not strengthen black any more than 
absolutely necessary.];B[no];W[pn];B[fq]L[nn][pm][qm]C[JB: But Black didn't 
cooperate, leaving the cut at "a" behind in order to play the kakari. \(A 
very good idea, I think.\)

OL: I would be tempted to play the double hane at 'b' immediately, so as to 
test white's responses.

If white answers at 'c', 'b' is a good forcing move, and black can take sente 
elsewhere.];W[eq]L[ip][dn]C[TS: This is a bit unusual, I think. 'a' perhaps? 
Or is that asking for trouble?  

JB: This makes Black solid, but perhaps overconcentrated?

OL: White should just play 'b'. Here again white strengthens black more than 
necessary. As a result, black gets a large moyo.

This seems to make the situation even again.];B[fp];W[dn];B[ip]L[jp]C[JB: I 
think "a" would be a better point. This looks a bit cramped.

OL: I don't agree. Probably Tero put a bit of thought into this and this 
indeed seems better than 'a'.

What is worng with 'a' then? Nothing immediately, but it is a half-measure. 
It does not protect either side completely.

It's better to protect one side and play a bit further away from thickness, 
the wall of black's.

After the actual move, white will find it hard to invade the bottom.];
W[cj]C[JB: Black's bottom territory is a fairly secure 25 points, but White's 
4 stones have mapped out a moyo of about the same size. \(But it is not 
secure yet, of course.\) White is going for fairly quick development.

OL: A good move. If white does not play here, black will very soon extend to 
'a'.]L[cl];B[gm]C[OL: Dubious. Black seems possessed of the idea of 
protecting the bottom territory.

Black should extend to 'a' instead, aiming to invade at 'b'. If white 'c', 
black could extend to 'd' and get something out of the top 
right.]L[kc][gc][ie][qi];W[qf]C[OL: Good.];B[mc]L[nc][qe][qc]C[JB: I think 
perhaps "a" or "b" would be better. Since thickness here is likely to be 
hampered by the White groups on either side, I would try to get some 
territory instead.

OL: It does seem as if 'a' was better, for now white can invade at 'c' -- and 
should do so immediately.

The likely result is white living in the corner and black getting a wall 
worth nothing.];W[nn]C[JB: This seems to be the time to make the cut since 
there is now a pair of moyos adjoining each other.

OL: This seems crude.

If we hypothesize a continuation to 'f', the marked white stone becomes 
misplaced, for it should now be at 'g'.]L[mn][nm][mm][nl][ml][nk][qi]M[qk];
B[mn]L[om]C[TS: 'a' looks more natural. If black is going to give in, P6 is 
better played at O6.   

JB: I expected "a" followed by a bit of a fight in the centre. I was happy to 
extend on the sixth line.

OL: Giving this atari is natural, since black is not interested of fighting 
inside of what would have been his moyo.

However, black's bottom seems to be growing faster than white's side.];W[nm];
B[mm];W[ml]L[mo][nl][om][ll][mk]C[TS: An overplay?   

JB: Most likely. But the cut at "a" looked like it might come into play, and 
b-c-d-e looked good.

OL: Most surely an overplay.

Black will solidify the bottom and reduce effortlessly the right side as a 
result of the cut at 'b'.

'a' is not very likely to materialize.];B[nl]C[TS: I felt this was necessary. 
W's area looks too big if I just hane.];W[om];B[nk];W[ll]L[mo]C[JB: This 
looks manageable, with "a" lurking in the background.

OL: Manageable, yes, but good, no. White will have to run through dame points 
in the center and black will gain lots.];B[km];W[lj]C[JB: My idea here was to 
chase the two Black stones a bit and hopefully 1\) Solidify the right side 
and 2\) make a bit more shape for my 3 centre stones.

OL: John seems to have it the worng way over. Black is the one doing the 
attacking.];B[ni]L[pj]C[OL: "Forcing" first at 'a' would be a bad idea. White 
would cap at the marked stone and black would be very much in trouble.]M[ni];
W[pi];B[oh]C[OL: I would be willing to try for a more efficient result, the 
combination of 'a' \(white probably answers at 'b'\), 'c'. ]L[pj][qj][ph];
W[oi]L[nj]C[JB: Aiming at "a", but...];B[mh]C[JB: This is a good reply that 
prevents it.

OL: Even so, it feels unimaginative. I feel black could try and push for a 
bit more somehow. Perhaps 'a'.]L[lh];W[mj];B[nj];W[ng];B[nh]C[OL: Now black 
is heavy and white seems to be ready to turn the tables and start attacking.];
W[kh];B[lf];W[mg]C[OL: This is a bad move. White solidifies black while 
gaining just about nothing. No more attacking for white :-\)];B[lg];
W[lh]C[JB: connects the white stones securely, and will allow the side to be 
solidified, at the cost of two stones. Seems reasonable.

OL: There are no new connections. White would have done better by trying to 
make shape some way, eg. 'a' and leave the marked stone for aji.]L[jj]M[ng];
B[of];W[pg];B[og];W[jl]C[JB: I think this turned out pretty much as I hoped. 
The right side is fairly secure, and the centre group has a manageable shape.

OL: Worng and worng. Even if the centre group is 'manageable', black has 
almost solidified the top right and the bottom. Black's bottom left is 
reducable, and the right side is smaller than it looks.

Black seems to be well ahead.];B[jj]C[TS: I felt B hadn't gained anything 
from the attack yet, so that I had to keep the pressure up.   

JB: I expected Black to secure his bottom area. This Black stone looks a 
little lonely.

OL: This is bad and dangerous besides. Defending the bottom is much more 
important.

If black 'a' instead, after black has secures the bottom, the centre group 
has to settle itself *_in_gote_*. This would be good enough to secure the 
game.];W[jm]L[kl][kk][jk][kn]C[JB: Push into the bottom, protect against 
a-b-c \(d is a ladder\), and expand the centre group to make it stronger. I 
liked this one. :-\)

OL: This move immediately gives black a reson for regret.];B[kn];W[ji];B[ij];
W[kl]C[JB: Time to connect solidly. If Black pushed through it would be a big 
loss.

OL: White's centre group seems safe enough and black has lost about 10 or 15 
points in allowing white to push with the marked stone in sente.

If anything, white seems to be leading again.]M[jm];B[jg]L[jn][jf]C[TS: Maybe 
'a' would have been better.   

JB: The two directions are certainly miai. I intended to jump to "b" if Black 
played "a".

OL: Kind of, but 'a' is certainly more important for black.];W[jn]L[mo]C[JB: 
There seem to be a lot of potential uses for "a" now. Black's attack on the 
White stones has reduced the lower territory, which is an undesirable effect.

OL: Which is exactly the reason black should never have let white through 
into the bottom.];B[jo];L[cl]W[gn]C[JB: "Contact plays for defense."

OL: This is slightly dubious. One only plays this way if nothing else works.

The reason is that if black gets a wall facing left, the invasion at 'a' will 
be severe.];B[fn]L[hn]C[TS: 'a' seems more severe, now that I look at it.

OL: Perhaps, but blocking on the outside seems natural in view of the fact 
that black wants a wall facing left here.];L[go]C[OL: Dubious. Letting black 
atari at 'a' is just too good.]W[hm];C[OL: Good. Black needs to secure the 
bottom to have any chance of winning.]B[go];W[hn];B[gl];
W[io]L[ko][mo][ho][hp][kj]C[JB: I thought that because of the cuts at "a" and 
"b", Black would have to defend there, and then c-d-e would give the White 
group 2 eyes.];B[ho]L[jp]C[TS: 'a' is definitely safer, but then H5 
practically lives. 

JB: Yes. This effectively stops the eye, but leaves 'b' undefended.

OL: A fact is that white cannot be stopped from living. This means that 
leaving 'a' is just giving up points. An almost sure way to lose.];W[ko];B[in];
W[ln];B[mo];W[lm]C[JB: So the eye appears elsewhere.];B[kj]C[JB: Black takes 
away the  other eye rather than defend the bottom territory. Correct, since 
White can no longer take the time to invade.];
M[ji][kh][lh][kj][jj][ij]W[ki]L[li][jp][hk]C[JB: Defend "a" and reduce the 
liberties of the 3 black stones.

OL: I would atari at 'b' first, just to test black's responses.

Furthermore, the three marked white stones are not that big. I'd try to 
escape at 'c'. Note, BTW, that black cannot connect with 'a'. This means that 
black also has to be careful after 'c' as there is a chance of the three 
marked black stones coming under attack.];L[jp]B[kp]C[JB: Perhaps a bit 
premature. White still can't afford the luxury of a play on the lower side, 
so no need to defend it yet.

OL: Not exactly. The atari at 'a' would be sente and ensure an encroacment of 
the bottom.];W[ii];B[hj];W[ig];B[if];L[hf][hg][gc]C[OL: White's two last 
moves seem to be in worng order.

Had white pushed first, black would be forced to go along with the tesuji at 
'a'. Now black can atari at 'b' instead, which would make an invasion at 'c' 
severe.]W[hi];B[gi]L[hg][gj][hk][ei]C[TS: 'a' seems essential.  

JB: But if Black "a", then b-c-d should get the White group to safety.

OL: The white group in the center is going to be safe no matter what black 
does. 'a' is better.];L[hf][hg][gg][ih][hh][gj]C[OL: I would hane at 'a', 
which is a tesuji.

If black cuts at 'b', the sequence to 'e' can be expected, after which black 
connects. After this, the cut at 'f' seems a most efficient way of settling 
the shite group in sente.

This sente would in turn be very useful at the top.]W[gh];B[fi];
W[hg]L[jh][ih][gg]C[TS: White has two eyes now. Not good...  

JB: Safe at last. Black can still play a-b-c but there are lots of ways to 
handle that situation. The top and left look pretty insecure now, though.];
L[cl]C[OL: Invading at 'a' is more urgent. Black's position there is 
stronger.]B[gc];W[gd];B[hd];W[hc];B[gf];
M[hf][gc]W[hf]L[fd][gg][jh][hh][jf][kg][ge]C[JB: Probably should have played 
"a" instead. The centre group should still manage. b-c-d-e-f and THEN push 
through, for example.

OL: Too complicated; white should just play 'g', which would make miai of 
living with 'a' and connecting with the marked white stone, even while 
capturing the marked black stone.];B[fd];L[gb]C[OL: Dubious. As the center 
group is alive, white should just secure life for the one at the top, by 
connecting underneath with 'a'.

The size of the ko that follows means that white has mistaken.]W[fc];B[ge];
W[gb];B[fb]C[JB: This is an enourmous ko.];W[gd];B[mk];W[lk];B[gc];W[ec]C[JB: 
There are fortunately some local threats.];B[hb];W[gd];B[mi];W[li];B[gc];
C[OL: This kind of move is usually bad.]W[ga];B[ha];W[gd];B[em]C[JB: This 
seems a bit too mild.

OL: Too small is the word.];W[fe];B[cl];W[cm]C[JB: I thought I had better 
solidify the lower area, and try to make use of the isolated stone later.];
B[dl];L[rd]W[qc]C[JB: Since I couldn't figure out what to do on the left, I 
decided to take the big point on the right instead.

OL: This is slightly risky. I wouldn't be confident of living in this corner.

I would just play at 'a' and take sente.];B[qd];W[pc];B[oc]C[OL: I would 
attack at 'a' and go for a kill.]L[ob];W[rd];B[ob]L[re][rc][qe]C[JB: This 
surprised me. The usual a-b-c would affect the White territory below, and I 
don't think Black can get much on the top edge with the now-strong white 
group there.

OL: Taking sente is correct.];W[qe];B[pe]L[eh][fg]C[TS: 'a' would leave B 
with reasonable prospects, though it would still be tough.  

JB: I though this was too small. I don't think White could have done anything 
here anyway.

OL: Black wastes sente, for there is nothing white can do here. 'b' instead 
would leave black leading.];W[dg]C[JB: This contact play seems a good spot to 
start trying to make use of the cut-off stone. I didn't really expect to live 
so much as to take as big a bite as possible out of the territory.

OL: Well, white still needs to do something to the right side...];B[eg];
W[dh]C[JB: On the other hand....];B[fh]L[ff][cf]C[TS: 'a' is correct.

OL: This is not so simple. The game seems to hinge on who succeeds here.

Accordingly, I probably would descend to 'b' so as to live -- and make life 
hard for white.];W[cf]C[OL: The vital point.];B[de];W[bf]C[OL: Now white 
lives and that means the game is over.

Black should resign.

Black eventually resigns. I end my commentary here.];B[bk]L[ff]C[TS: B has to 
play 'a', though W then probably lives with B9. 

JB: That is what I expected.];W[ce]C[TS: The end. I made a few more futile 
attempts \(way too many, actually\), then resigned.];B[gg];W[he];B[dd];W[ef];
B[bg];W[ee];B[bd];W[cg];B[bb];W[cb];B[af];W[bh];B[ag];W[ah];B[ae];W[ba];B[ci];
W[ch]L[di]C[JB: I could have played "a" if I had stopped to think, but I this 
makes the liberties 4 to 3 and makes the outcome clear.];B[di];W[ab];B[bi];
W[ac];B[co];W[cp]C[JB: Playing safe.];B[bo];W[bp];B[bm];W[er];B[fr];W[kc];
B[br];W[cr];B[bq];W[aq];B[ds];L[es]C[Black resigns before white can reply. 
"a" is adequate.])
