;W[cl]LB[dd:E][ck:C][dk:D][cl:F][dl:G][cm:A][dm:B]C[A & B are the severe pinches. They are popular because they make more of a demand, taking control of the white part of the board (this assumes that E is white. When E is black, everything changes.).

C & D are the least popular because they effect black very little, but put more energy into ballance and developing the left. This was more popular 30 - 40 years ago when Japan was the leader in Go and the artistic side of Go was the norm. I really miss those days.

F&G are most popular because they are a good combination of both ballance and control.

]
;B[jc]C[Black breaks from a straight forward game.
Instead of defending his stone, he looks for profit and to make an area that He can control.


White has a decision to make.
Punish black for ignoring the pinch, or stop black from his plan.

We are still in the early opening, where vague attacks are not so big. So white stops blacks plan first.

;W[cp]
(;B[iq]LB[ql:B][do:A]C[Black again breaks from the norm, going for profit.

When white captures with A, it not only takes that area but also builds a wall.
So this black move is removing half of the value of white A. please look at the variation at move 1 to see this principle again.

When white sees this black move, he is expecting black B next.
]
(;W[do]LB[fq:A][gq:B]C[At this point, white B would increase a big solid territory with sente value (not actual sente, but with a future).

So black A or white B is big (not big enough at the moment, but soon).

If white wants to do any work in area 1, 2 or 3, he needs to defend.

(;B[ol]LB[qh:A][pn:1][lq:2]C[White is fine now, and it is unreasonable for black to play around A trying to attack.

So, white is free now to deal with blacks bottom moyo.

First we must decide, invade or reduce?
There is zero feelings of "Black is too big!" or "this has gotten out of control!"

So white can play calmly and comfortably.

If we could not find a way, then we might probe in order to uncover a path. But the road is an easy one.

JamieNoGo [-\]: box

Notice that without black A, white has many interesting probes at the squares spots. Black A finishes the area making it strong so that the probes lose their interest.

Notice that Black B no longer sketches out black's double wing.
Notice that white C no longer has any sente value.
Notice also, that black now has thickness (marked) and B or C both play near thickness, which is usually not good.

For white?
Black has 3 running directions so white will choose which is best to remove.
Do any have special characteristics? 
   yes. Black's B stone has good aji, especially with the C stone nearby.

JamieNoGo [-\]: I thought 2 was good enough
]
(;W[cj]LB[co:A]
(;B[eh]LB[ec:C][hc:D][id:B][gh:A]C[Seems 4 ideas.
A attacks directly, but there is a lot of room all around for black to run, making it vague, so it's a bit early for that.

B is a leaning attack, but a white stone at B would be far from home. So it's too early for that (and even more vague than A).

C is big for sure, but no attack at all.

D plays in the last big area, threatens to invade the top next, and patiently aims at the black group.

We often make a point of playing on the 4th line to keep the pressure up, but in this case  there is little value in a 4th line move and little pressure to apply.

hmiku [1k\]: B would strengthen black's 3 space gap on top in exchange for an unsure attack

(;W[hc]LB[ec:2][lc:1][eh:A][hn:C][lp:B]C[Black wants to support area 1, invade area 2, and defend the A group.
There is no way to do any more than 1 of these. So black is feeling a bit behind now.

The open marked gap has a lot to do with the choice to attack also as we will see.

If A was weak, or if C was not thick, then he would be waiting for a better time to attack.
