I'll stop to use the Diamond Opening, because it must lead to the Cosmic Style. I love the Cosmic Style. It's difficult to make full use of it, though.
My 46th KGS game (vs [10k], Komi: 0.5, W)
I made thickness in the center. That's why I thought I was leading. However...
The opponent broke the white fence at the right side from paying wedge at A. Although I thought it was even at that time.
However the white fence at the left side was broken too...
I resigned. All moves are here.
The Cosmic Style is too difficult! I'll stop to use the Diamond Opening!
Good bye the Diamond Opening!
