Zi and Li have different oppinions about how black should follow up after black B, white C - see the variations.]

I thought at that during the game, but I rejected it since I felt it is too soft on white.]

(;B[lq]LB[pk:D][nm:B][qm:C][pn:A]C[Black should answer either A (white will respond at B) or C (followed by white D). 
Basically, at this stage white doesn't have much freedom since it is weak, and will respond with ikken-tobi, so black can aim at ikken-tobi cut later. While if black doesn't do anything and lets white play first, white will have the option to get aggressive and reply to push with nobi instead. See variations.]

(;B[of]LB[og:D][pi:C][om:B][pn:A]C[Li: this is so bad for black - white is happy to reply, and black has no follow up; should instead force A-B then pincer at C to not allow white to make all that territory.

D was suggested by Ben after the game; Li agreed that locally, D is the better pressing move, since it has follow ups.]

When I analyzed the game with Leela, it prefers to play at B or C instead of connecting, after the triangle exchange.]
