Life In 19x19

Here's Aphelion (B) vs Karaklis (W) #1. Result is B + 5.5.

Through out he game I felt I had alot of problems preventing Whie from getting a big moyo by attacking my top left group. Any advice would be appreciated!

You're about 12 stones stronger than I am, so feel free to ignore me.

193 looks suspect to me. Why there? I might be missing something, but it seems you gave those three stones to your opponent. What happens if you play at E2?

Suji, 193 was a bit of a missread, I was afraid about losing the second eye at F3 if I saved those stones, not realizing that my bottom would already have a living shape.
