Hello everyone,
this time we will discuss a Go Seigen game played and Fujisawa Kuranosuke,
later known as Fujisawa Hosai. The game was played in March 1953
Go Seigen wore black stones.
This joseki going to play here, rarely seen today.
White takes territory, and black influence
In the upper corner they will make a joseki that it is more common today
At this point in the game it could almost say it is a little better
black, since White is lost in this side of the board and
Black occupy the rest with influence.
Black stretch
It could have been here but it is open,
This is the point
white kakari
The usual answer is this,
white extends
It could not be keima that since it would give the opportunity to black press in this way
combining well with these three stones, therefore this is the best move for white
Black runs.
Another possibility was there, but it leaves an invasion easy target in this way.
The possibility of playing in the focus had
disadvantage that leaves easy for white invasion in san-san
since either side by black block which makes inefficient
or this or this stone, if blocked by Here, this stone
It is inefficient, however if this stone It was there, which is where he has played,
San-san is easy answers because this is the wider side
This is perhaps the reason why Go Seigen chooses that point
White extends here. This is a very big move, delimits a lot of territory and increases
pressure on these three black stones. White is perhaps waiting for this movement
that would be met with keima, being favorable position white
This is unacceptable for Go Seigen, and thus jumps.
This point or this area is desirable for both players, if turn white, or something like that
delimit a great Moyo, and playing Moyo is black on this side
As you can see here there is no white stone
It's time to go, do it this way white
black extends
white here
If black would respond in this way, this gives good shape to white,
So black plays below,
Extira
keima
This move prevents grow the black moyo
and reinforces or strengthens the group White
In this play, it usually responds well, but now ... now ... this move by black
It is logical since the situation is more balanced, but
both players are playing tenuki, and in this case white will not play that way
but it increases the pressure on these three stones,
If black jumps,
Now, White could play nobi, and this situation is more favorable for white
since the black has a black floating group, no base is
well established in this side
In this move, black responds again tenuki
playing well and white near the three black stones above
this move,
besides ensuring corner it is looking at these stones, leaves the future
something like this,
this wall is weak
Now, this play, this and this, are miai. White is expected this.
Black White takes territory but change takes strength and influence in the center
It was what White expected, however, Go Seigen will make a move
perhaps unexpected, he plays ogeima; this play in a way to mark the strategy
all the rest of the game
Now if Black plays tenuki
Because of this white court could very easy to live this way.
Black has to defend, and this extension leaves this group based
enough to live, therefore, black
play thus preventing this target group stated
extends
this blockade
while maintaining the pressure on this target group, says the corner
Keima to escape
This continuous play with the idea of this, to keep the division
between these two groups that will go Go Seigen attacking alternately during the game
Hane
stretches
Kosumi, to connect
Now Go Seigen played here
Go Seigen said at the end of the game that this movement is a little slow
Perhaps it would have been better thing
You are using these stones be cut ... prevent connect ... and something
The weakness of this group is, but Go Seigen played solid here. It is a movement that
well reinforces these stones
After this move sequence above no longer makes sense because
this stone
These two stones are quite inefficient and also this exchange
favors the target group, therefore this sequence is no longer interesting
Black will play keima. No court has problems because if you try white
It is this weakness
this cut is quite strong, so So you can not cut, white defends
Black keima again, keima, is looking for a connection there or go here
and make room
This move is to refozar a little this group, and sente because if White does not answer,
this sequence is inadmissible for white, after playing here ...
This is unacceptable for so white both must answer here.
black here
Now it would have been the easy move for White to play here, stabilizing this group as
It is practically alive, however White note the weakness of these
three stones and see that they can cut, and what they do, because if black plays
thus cutting leave a good and comfortable position for white and
these four stones are now quite weak, therefore, can not black
play there. Go Seigen played here, and after this movement seems white
the result is quite favorable for white has achieved this column
Central, enough strength, these three stones remain weak and
not expected to be any problem, however, after this move
normally
crashes, in most cases be blocked in this way, however
Go Seigen here had expected This cut is quite strong
... because we can interleave this sequence ...
Now appears weak white
That is the point at which security white group is in question,
It is quite uncomfortable, therefore no It can be locked at this time
White plays first here, if black Hane, now can be locked, since
cutting is different
not weakness appears,
therefore, black does not respond here but stretching
and we see the enormous power they have achieved black in the center
white Hane
and now the black initiate a strong attack on the white group,
that way
White connects, here would have been more I Hane easy to play, because if black blocks
These two stones are hunted, so both the target group lives
However, playing first connection,
White can not defend, you must leave, bamboo knot, looking for the connection ...
And here
Black here, and this move is sente since after playing here in this area there are court
the group still has no eyes, Here are cut, danger, therefore
white add one more stone for the connection is solid
and now black plays in this way, stabilizing the entire center and
stones that are weak have left to become pregnant and concern for
White longer this group and now the above
Play here. Now let's see a subtlety of Go Seigen
Would cut here ...
For this group is reduced to the minimum
expression and may not be able to live, but the court does not work, as we shall see
white kosumi
and has binding
Then, the cut in this way does not work
Before playing this, Go Seigen comes here once again making use of these
three stones, because if white plays well Now the sequence we've seen
it works,
... and there is no connection
White is cut and has difficulty
live there
Thus
this play
White can not answer here but here
making use of dead stones
atari
atari
This move is tesuji, because if black comes here, is is this cut
that if he defends, is perfectly connected,
and if it comes up, atari ..., no connection, no problem,
and white is threatening to play here and capture five stones; If black defends
for white connection it is very simple, no It has problem
At this time, Go Seigen
Play here
abandons these five stones, on the other hand is almost
best choice for white
here you will not play because black short all,
Nor did it this, since
come here, first atari, is there, and atari, no escape
It is almost forced to come to eat these stones, and now connects black
thus keeping this divided group, keeping the pressure on that group,
in exchange for having delivered these five stones, and even having left
This point is very large in favor of white and also this move is sente.
The game'd rather good for white as long as this
group to achieve live; it is the turn of white and play here
White is waiting for a response so black as to defend the
territory and easily live without But Go Seigen
perhaps he had anticipated this and had prepared the answer, here
this movement, tesuji, hard to see
is that the target group can not make eyes
let's see some sequences, example, if there is ...
Although black loses these two stones, leaves no eye, the white group is dead
and if he comes here ...
... and this move kills the target group
since this and this are miai.
The white group is dead
In this position white they decide to leave the group and try to compensate for that
loss winning the corner, play here
Go Seigen currently plays here and it is questionable if he could have played
here to save the corner, since white group could never escape
White here.
This is very painful for black. Star losing stone
but they manage to live in the corner in small,
and white now take perhaps the biggest point
currently on the board that is here.
Black must now live, playing there, but
first try to make this kikahsi, which is a mistake because Fujisawa see this tesuji
since black can not cut
They appear these two weaknesses, and the target group resurrects
Play black
This exchange is bad for Black, now must live
Not worth the cut because he plays there, you have to play here first
connect
And at this time the game is White favorable since they have one quarter
board, practically, this side, this corner, and change only black
They have this corner and this group. With a movement like this, ensuring that
lateral possibly white winning the game, but there was another movement
very big this further erodes the possible territory
black, and also prevents a possible invasion of this type, and choose Fujisawa
this movement, and this gives the last chance
a Go Seigen to win the game, again taking advantage of these three
stones that were lost at the beginning.
and now White can not play this way
that follow a sequence such
and he connected, and also the white group is still alive, which would now heading
favorable to Black
Thus, white can not play here, you have to play below
must cut
Kosumi. This move is possibly Ultimately, because after bamboo knot
threatens to cut the group and have two cutoffs to save these stones
White connects here that is threatening to go in there and get that group,
but black makes bamboo knot,
It is threatening to cut here and now white decides
save this group is larger,
short black,
white connects
And with this move, White is forced to cut here to save this group,
and connecting black is final,
these parts are dead, saved these stones, these are now muertasy
and these three are recovered, since white can not leave here, 1, 2, 1, 2, 3 ...
and even if you connect ..., 1, 2, 1, 2, 3 ...
That is, the game has overturned awesome here,
White has been dead, black has these stones recovered, he saved
these, has captured these ... and although the game continued some more movements,
White abandoned. We have seen with what skill Go Seigen
He has pressed on attacking white alternatively the two white groups
playing with the influence of their stones.
A historic and masterful game
