Can you explain the exchange at 19:15 of black hane 5-7 with white connect 8-6? I thought white had cut black off in the center but now black is connected and white needs to worry about eyeshape?

It had something to do with the top right corner of the white being able to make out its living by ko(?)(劫).
at 15:12 why wouldn't white hane 1-6 (1 move down form prev move) and start a more favorable ko? if this ko is still not favourable why not play the bump variation but simply not kill but protect the cut at 5-5? then after black makes life white has a imo more clean cut

because the corner originally belongs to white and the hane at 1-6 as you said would just start a ko that white could not bear. It does not matter to black if it loses the ko but the white will lose the entire corner plus the whole group on the right will be too weak to involve in the fight on the right side. And if white protect the cut at 5-5, it's just the same result. Black gets to connected and live, white lose the whole corner and not even have two eyes, and it is extremely disadvantageous for white to fight black in the situation like 17:19 Furthermore, 5-6 is a more clean-cut compared to 5-5 at 15:12 situation since the whole white group would be too heavy and weak, and white still need one more move at 5-6 to connect. As a result, white thinks the best way to minimize the loss is to let the black take the corner like 16:37 so white could place 5-6 to connect itself, cut the black and the gorup would have enough strength to fight the black in the battle happen at 17:19

Idk if you are referring to the same ko as me drive.google.com/open?id=1uBHI7eKefCfrxI1-5k4GTGu2alNiGsbZ regardless of whether fighting ko is good here this is definitely the better ko as black needs another move to capture whites two stones after winning the ko anyways I don't see how this cut is not more solid drive.google.com/open?id=1ggp13kvV4s3AhPIz2zicsjuAGxvQX0Nn where for solidness white can play 3 at 5-6 in which case your 5-6 stone is connected solidly to your group
