tderz's 3 questions:

• 1) Black B189 at c?
• 2) Confirm that after B215 bent-4
• 3) How to shape this stuff here into Senseis diagrams?? (in an easy way)

Question 1

Move 189  

While replaying, I wondered if Black attacks at c?

• Are the 4 stones important?
• Black can save the important part - or not?
• Black was winning anyway, so it does not matter so much.
• There must have been complications and reasons not going for the kill of the big white group with move 189.

• My question: what were these complications?

White connects back?  

unkx80: I suppose can connect back?

I thought of this - but it's a hallucination  

tderz: Thanks for replying to the questions,

I should have seen this myself!
I only hope that I did not think much at all, otherwise it's embarassing to overlook this connection.

Question 2

Move 215  

I think after 215, the lower right corner is dead by bent-4.

White lives.  

unkx80: to lives. However...

White loses anyway.  

captures two White stones, so I suppose White loses anyway.
