The weakness is that W can invade in the left side around A to put pressure on B's upper left group. The strength of B11 is that it works very well with the moyo on the lower side which would enclose more than a quarter of the board. ] LB[di:A];W[qo] C[This shows Lazarev's style, as I remember it and mentioned at the outset, but in this case, I question the overall positional judgement. W12 follows the proverb that you play the shimari after taking the corners; enclosures and approach moves come second. But in this position it would be better to play in the center of the lower side at A to reduce B's space. After a W play in the vicinity of A, an invasion on the left side would be more effective, because B will have less space to enlarge on the lower side. ] LB[jp:A];B[jq] C[Natural move; choice between a play on the 3rd or 4th line is style, hard to say which is better] (;W[lq] C[Again, W is taking territory. a more well-balanced move would be to play at A: see variation] LB[jo:A];B[jo] C[this is an idea way for B to play two stones on the lower side. B has two weak points -- A & B -- but B's moyo is now so large and flexible that it can be centered on either the left or lower side, making it difficult for W to choose an effective invasion point. C is a move that I might choose, to handle this problem, and to emphasize the strengths of W's position. ] LB[di:B][dq:A][in:C] (;W[ck] C[This is an unorthodox invasion point] (;B[ci] C[looks weird, because W had no way to make eyes here anyway; I prefer A or B. ] LB[el:A][ek:B];W[ek];B[gk] C[that's good];W[ei] (;B[cj] C[making sure B doesn't have eyes while strengthening his own group; very conservtive way of playing. I still prefer the jump at A] LB[ge:A] (;W[em] C[W is paying attention to Bs entire moyo, erasing from above, which I think is the correct way to do it] ;B[cl] C[again, a solid move; now all of B's stone's are connected. You could say that W has played kikashi here, so his invasion has worked fairly well. But the next move is difficult for W to choose, because W doesn't want to be too heavy. W's entire group (marked stones) is very light and could even be discarded at this point. What W must focus on is on the potential to put pressure on B's marked stones, so W should be looking for a way to get into the lower side (see var) ] TR[jo][jq] (;W[fh] C[The more moves W plays to save this group, the better B's play on the left side becomes, as all of B's stones are necessary now.] ;B[fp];W[cq] C[big move -- almost 30 points -- but it doesn't affect the strength of B's stones, which are all connected now. A play at A is also possible but is a matter of style. ] LB[qf:A];B[cp];W[dr];B[fr];W[bp];B[bo];W[br];B[ap];W[bq] (;B[nq] C[This is a choice, one way to play; call it style.

They must be saved during an attack, but once you stop attacking, must be prepared to discard. ] TR[hj][gk];B[hc] C[a timely tenuki] (;W[nc] C[If W approaches from the other side (see var), B winds up with a big terr on the upper side] ;B[oc];W[nd];B[pf] (;W[jc] C[Over extension, but since W is already in trouble, he needs to create confusion] ;B[lc] C[natural];W[ld];B[lb] C[the two connections underneath are miai];W[pc] C[so W tries to eliminate one of the miai] (;B[pb] C[B gives up his attack in return for a secure terr in the upper right.

Plus B is helping his group on the left, which looks fairly safe but only has one eye.
