PW[Koroviev]PB[Sku]AB[dd][pd][dj][pj][dp][pp]C[Here is an idea for you to experiment with in high handicap games, at least in the opening -- play only moves which keep your opponent's weak groups separated.  Do not try to kill, do not try to enclose your own territory, do not try to save any of your own stones which are attacked (unless they are cutting stones), just keep your opponent separated.  With this strategy in mind, see the following comments.]

;W[jd]
;B[jf]C[Excellent, W has two stones on the board, so B disconnects them.]
;W[qf]
;B[nc]LB[kd:K][ld:I][ke:J][le:H][me:F][ne:D][lf:G][mf:E][nf:C][of:B][pf:A][ki:L]C[Not bad, but oriented toward safety and territory.  Try any of the marked alternatives to pursue the separation strategy.]
;W[rd]
;B[ld]C[Good]
;W[qc]
;B[pc]LB[ke:A]C[Just a safety move, not very big.  How about A instead, connecting all your stones and preventing any possibility of W connection.]
;W[qe]
;B[pe]LB[of:A]C[Nearly wasted move, because it has no effect on safety or connection of W or B (and does not even make significant territory).  Best is to play elsewhere, but if you really want to play around here, take a look at move A.  This stone would be connected to the B stones below and would get B out further and faster into the center, hence is more efficient.  To prove that A is connected to the stones below, take some time to read out how B can refute any attempt by W to cut through.]
;W[gd]
;B[id]C[Great move, if you can separate these two W stones.  Not so great if W ends up capturing this stone or connecting underneath.  It takes experience and reading ability to know if this works, but at your level it is great to try.]
;W[he]
;B[ie]C[Perfect, separation achieved.  W should try very hard to avoid this result.  If there is one lesson for W in this game, it is to avoid this result.]
;W[ec]
;B[hc]LB[dc:A][hf:B]C[Can W connect underneath if B does not play here?  Try to read out some attempts.   If W could connect, then this is a great move.  If not, it is not worth playing.  Blocking at A in the corner to make territory and deprive W of a base is objectively best, but to pursue the separation strategy, how about move B?]
;W[dc]
;B[ed]C[No good, because W connects easily here, then the two B stones just end up weak.]
;W[fc]
;B[ff]LB[hf:A]C[Good idea, if you intended to play A next if W passed.  Unfortunately, it is weak tactically, since W should not let you enclose him so easily.]
;W[cd]
;B[gc]C[Bad move.  Yes, it threatens to cut, but W will obviously connect, then the exchange accomplishes nothing.]
;W[fd]
(;B[ee]LB[hf:A][pf:B][og:C]C[These two B stones are not cutting W into two groups, and they are not making territory for B, so they are strategically unimportant, making them prime candidates for sacrifice!  Look at the big picture.  

Move A is still good locally, primarily as an attack on the center W stone!  A variation is shown if W really wants to capture two B stones.  

Moves B and C are also good, again isolating the center stone, while expanding B territory as a side benefit.]
;W[ce]
;B[fb]
;W[eb]
;B[gb]C[B gave up sente here to make just a few points.  This is a late endgame sequence, much too small now.  It would be important if it affected life/death of either group, but that is certainly not the case here.  Look at the big picture.]

;B[ef]LB[hf:D][dh:A][di:B][ei:C]C[Oh no!  The last two forcing moves prepared a continuation to separate W and connect B (any of the marked points).  But this move is the same as passing :(]
;W[dh]
(;B[gf]LB[hf:A][hg:B]C[This move just urges W to break through the containment.  Moves at A or B might actually prevent W from breaking through here, but then he could just continue toward the center from the other side.  The best plan is still to discard these stones!  After all, they are not separating any W groups, so what is their purpose?  They are only a burden for B to defend.  See the variation for an example of a way to give them up and get a nice result.]
