;W[nf]LB[jc:A]MA[kc]TR[oc]TR[pc]MA[jd]MA[kd]TR[nd]TR[nf]C[I get the idea of this, but given the vast space in between white's positions, and the fact that the white wall at d15 isn't all that strong, it makes way more sense to do a standard extension along the top, which will then coordinate with the wall as well.   Something like A or one of the X points.   This leaves open such a big space that splitting it with an invasion should be easy and valuable, since white has expended an extra stone here building outward.  I black invades the top and makes a stable group there easily, how valuable will o14 end up being?   

Part of the problem is that the marked white stones don't have a base.   So now white has two formations which hsve influence but not a stable base or thickness.   If one or the other was truly *thick*, it would be much more dangerous for black to invade the top, and the expansion might be a good strategy.]
;B[jp]LB[ic:A]C[Invading around A is significantly bigger than other large points because of white's overplay at o14.   ]

;W[je]LB[hc:A]C[removing one side or the other seems a better strategy.   This move is designed to create white influence and thickness toward the center.  Where does white intend to use that thickness to profit?]

;W[jb]LB[kd:B]LB[ld:A]C[this seems like an odd move.   It's not crazy, because of the white capping stone above, but it doesn't really work better than other options here.   

White has so far committed two stones to a "seal in and make thickness outside" plan.   Why not continue with something like a or B.  At least that has the virtue of assuring white's strength and connection, even if it gives black more than they were probably entitled to here.]
(;B[kc]LB[ib:B]LB[kb:A]C[AI seems to think this is ok, but I like A or B a lot better, pressure or capture this stone to make good shape and eyes.]

;B[ke]C[It's rarely a good idea to push into a knight's move if you cannot, or do not intend to cut after.   Bad shape, and it just strengthens the opponent, and may remove the ability to cut later.]
;W[kf]
;B[jd]TR[gc]C[this move wastes the aji of the marked stone.  It pushes white into connecting up.  Also pushing into the knight's move where you aren't about to cut, always a suspect plan.   The reason the AI keeps wanting you to play j16 is because of the h17 cut.  Note, the cut doesn't have to work in the sense of capturing or connecting back to be worth it.]

If the 3 stone advantage is real, should have been little problem making up this deficit the rest of the game, but a lot of players get frustrated after losing fights like this.]
