;B[nl]LB[ml:C][ol:A][mm:B]C[I felt desperate now, when feeling behind i should cut and fight?

skydyr: Why desperate?  It's hard to cut white off from the center, and white has an eye in sente at K4 and another in gote at F5.  Time to take a big point like K16 or undercut black at R11 or something.]

;W[fg]C[skydyr: White made a big gain on the top, but the game is far from decided.  If black had invaded at, say, C17, it's perhaps possible that white has enough outside strength to kill.]
