Awesome game

Below is a game between Geller and Kogan. It was an amazing game I found but I still have some questions about 2 of the variations I added (move 17 and 29). I would really appreciate it if you could give me an answer (or perhaps the book is written incorrectly or white got lucky). Note that the ones that has the comment '(added variation)' (I think almost all of them has added variation) might have some mistakes in them (because I added them), so please tell me if you think I missed something.

o sorry,

on of them is on move number 17 (black to move), and the other is on move number 29.

thank you for your interest.

 I don´t get why those moves were played,
