;B[oj]LB[nc:E][qf:D][ch:A][ol:C][fq:B]C[DW - This is the 2nd Installment of considering the position. 

How to use a wall ?  I suspect most of our readers would prefer to play black in this position because it is not clear how to use the 7 stone wall in  the top left. In this series I have cherry picked positions which are interesting to me, but try to pick out represenative examples of the correct direction of play

How should white play?   

CHH Black 17 is a declaration of war 18-21 are preparation for the battle. 21 has a secret aim to attack the 7 stones on the top left.

(;W[fq]C[White would llike to map out a large framework with 1 and 3 but after black plays the vital point of 4 black is in trouble, if white continues with 5 then 6 looks keenly at the "big dragon " in the top left the white stones are now floating and a liability. A failure ];B[dn];W[ip];B[mc]

(;W[ch]C[If instead of 5 white plays 1 this is even worse. 2-13 white can live in a low position 
actual translation is "back handers chore" but black has a good position and attacks with 14-18 white lacks a good strategy.

(;W[ol]C[CHH " white 1 ignorantly jumps to the centre at a bad time"  Black 2 is a vital point. White 3 and 5 follow but white suffers as black takes territory in the last corner with 6.The result is a white miscalculation. ];B[mc];W[eg];B[dh];W[fi];B[fq])
(;W[qf]C[CHH Finding trouble. This is the worse choice black 2 is vital and after black 6 white is in danger of a splitting attack on the two white groups ];B[qe];W[pf];B[nd];W[nf];B[ld])
(;W[nc]C[CHH Good direction ; white 1 first looks to the top to settle the shape. If 2-5 white is in a good position for the battle ahead

DW I take the main point being that after the top is settled white will be able to attack very strongly without ever  worrying about the 7 stones on the top left, which will turn from a question mark to an exclamation mark for the rest of the game !

After the continuation black has a thick position and can't be attacked.  Whites stones are not best placed. Black won by resignation after 199 moves.  ];B[lb];W[mj];B[ol];W[qn];B[rm];W[qm];B[ph]))))
