I don't really see the point of that last move. The peep at C16 seems to be much more severe. I am either missing something and should be nervous, or my opponent made a mistake and I should be happy. If only I could figure out which.
The "probe" on move 82 does not strike me as a particularly good move. The following would have been better, which can lead to a ko in the corner, as shown:

I dunno, this way black can live unconditionally in the corner later with d18 and tripod group (or else cut off f18 which is adequate compensation). Usually f18 could mean the tripod is dead, but black can use e18 sente to live for the cost of hurting f16. That attachment probe can be a good timing in this common shape to create the right to live in the corner later as given black just slid he's not going to allow it to get cut off. (B could choose other answers for 3 like a/b but white still has aji to utilise in the corner.)

W can reply with 2 above. If B persists in the corner, he runs our of moves. So a better bet maybe to try 1 below first.

B takes gote if he protects at 3, although it will be big if played at the right time. But the corner exchange is bad for B here - it clearly loses points.

would have been better, which can lead to a ko in the corner, as shown:
