Well, you got there in the end, and well done for maintaining your focus. It is very hard to find the optimum moves when you have so many options available. I think, Erika, you probably should play rather stronger opposition than this, who will be more testing of your play.
I agree with ION. That's why, if and when Erika wants, I'd be happy to mentor her again. There were a bit of missed opportunities, still. Yet, Erika didn't make a terrible that gave up her advantage. But, you can learn from stronger opposition, Erika.
