this is a very nice and solid move for black.
and can be played without fear.
next black can aim to play at a or b.
it's more or less a miai situation.
if we go back a bit to this position, we saw that white can approach the upper right corner.
but white can also use this aji.
white can approach here, aiming to play at a later.
playing here starts a bit of a complicated variation.
let's begin with the simple variation first.
that's just playing simply here.
this is a very simple and clear move.
it's a little bit crude, but after this you can play tenuki as black.
so this is certainly possible for black.
however, [this] starts a bit more complicated variation.
white has 2 options after this.
white can either play here..
or..cut!
let's have a look at the cut first.
black has to reinforce for his two stones, and white extends...
and after this white can jump.
mind that white does not have to make the exchange of [1] for [2], because it is sente anytime.
so black can not cut white.
what we mean is: when black tries to capture this stone..
white can simply push [here], and when black defends..white can connect in sente.
instead of [this] move, white can also take it more easy and just extend.
after this hane it's very tricky and black has to be careful.
if black plays the cut now, he makes a mistake.
white will force black into a bad shape by playing atari here and then blocking on this side.
this block becomes sente for white, because otherwise white will go through at [1]
white got very strong on the outside.
so instead of cutting immediately, first black has to push.
if white extends, black will cut anyway.
this is good.
instead of pushing here, white can also play the hane.
black will answer with this strange move.
eventhough it's an empty triangle, it's a good move because a and b are miai.
when white defends here the cut works again for black.
and if white protects the cut, then black will create some aji in white's position.
after this it's not urgent for black to save the 2 stones.
black will play on the second line.
if black omits this move then white can play [this] move and destroy a lot of black's territory.
when white plays [here], we've seen that black plays the keima.
but if black plays somewhere else, white will approach this corner.
it's a nice placement for white.
this is why [this] is a good move for black.
when white approaches here..black is a little bit cramped.
white will play on the second line here and white is happy.
black feels under pressure.
in [episode #5 payback time] we've seen this shape.
if black plays hane it's a little bit dangerous.
white has this tough spot.
after this white will hollow out the corner.
and black is in a lot of trouble.
so instead of playing the hane it's better for black to just jump away.
however, black doesn't have a solid base.
check out [episode #5] if you're interested.
now that we have seen what happens when white plays [here], let's have a look at [this] move.
why is this such a bad move?
it's quite surprising that it's bad because it looks like white is doing good moves, and he's making territory.
yes, the lower side looks quite nice, right?
right.
but black has [this] move!
it's a painful invasion.
black can still live inside white's territory.
black can live because he has [this] aji.
this helps a lot in combination with the black stone at [a].
let's see how black can link these stones.
black destroys all of white's territory and is happy.
how about jumping to here?
yea, it looks like a solid or strong move.
but in fact it's not good.
[this] move is very urgent because it prevents white from invading at the 3-3 point.
if white plays here to protect against the invasion, black will play like this.
the [shoulder-hit] is the [vital point].
white is flattened.
after black got the lower right corner he also succeeded in reducing white's framework.
this is ofcourse good for black.
instead of defending here, white can also consider defending the lower side.
however, this is actually quite small because black has very good endgame here.
white's territory is not that big.
it will be reduced greatly.
the last possibility for white, after black plays [here], is to simply play tenuki.
however, this leaves a very big hole here.
black will invade, giving white a very hard time.
black continues at a, b or c to handle the situation.
white has a very thin shape.
so now we've seen that this is a bad move for white.
how about approaching from [this] side?
this one?
white can also approach from here.
black answers normally.
but now this is a very big point.
and this is the reason why lee changho chooses to play [this move].
he doesn't want to get under pressure as white.
right.
so let's maybe first have a look what happens when black [doesn't] play like this, but plays [here], this is the normal move..
it's also a possibility, however, it gives white the chance to choose between the normal joseki - playing at [a] - and approaching the corner at [b].
this would be normal but now white can also play [here] to strengthen his own group in the lower left.
and to attack the black group.
so this would be a nice move.
