10k lost in the middle game? How could I solve this?

In this game I felt, I made some mistakes as black, but I cannot tell, how I could do much better. In particular, white could save his group on the right. I wonder, if I could do better in the sequence starting with move 61, so I could kill white.

Furthermore, the reduction of white’s moyo starting with move 119 was not as successful as I hoped it would be. Do you have any advice, how to make it more effective?

By the way, move 197 was stupid. You don’t need to tell me about that. :wink:

You would have killed white on the lower right corner.:slight_smile: with the following sequence. https://online-go.com/review/245881
