C[I think getting cut in the center was what really hurt you that was easily a 70+ points loss that could have reasonably easily been avoided or reduced remember to sacrifice th small to save the large]

;B[co];W[bo]C[actually this move may be a bit early white can't rescue C6 stone and once black exchanges B6 forB4 he can block at D4 which is sorta sente unless white wants to exchange C4 for C7 the urgent move now is E2 or D3 later on you can still play C7 which black can't answer very well]

C[If B6 is sente then C7 is urgent exchange that move and then reduce the wall]
;B[bn];W[ar]C[my life and death is not so strong but you must be carefull of the life and death in this situation in the game blacks capture of C6 or move at B7 became sente so be very careful of this I thing A3 is better blacks capture is not sente]
;B[qj];W[jc];B[ao];W[ap];B[cm];W[hq];B[bq];W[bk]C[okay threatening to escape B6 is good but do be sure of following through reasonably soon otherwise its just a 2nd line move in the opening and one next to a thick stone]
;B[cc];W[eb]C[you should learn the proper 3-3 joseki]
(;B[ce]C[not good white can push and cut]
(;W[df];B[cd];W[dc]C[black should push at D15 then white will have 2 cutting pts after E15 then C18 is okay although I would prefer B13 first as it threatens to cut or clamp]

;B[ro];W[qn];B[rn];W[qm]C[because you haveQ7  this move can be omitted for speed H5 K15 M16 are large]
;B[pr];W[nq]C[blocking at P2 is crucial 1st if black gets that pt white will be short of territory 2nd even if white gets it later it's not necessarily sente if white captures Q2 in sente later O3 is awkward (unnecessary)]

;B[jo];W[fo];B[hn];W[hl]C[black stabalized easily and white still has a weak group]
;B[jk];W[ki]LB[hi:A][hj:B]C[H 8 stones in danger because you commit H8 heavily they cannot be sacrificed]
;B[jh]C[slow better to attack with H10 or 11 this stone also helps J13 provides excape route]
