I tried to kill black's corner. White is short on eyespace and nothing works. And yeah black can cut white with easy moves :((

Hmph. I should have asked about that move before when we discussed that position.

Sorry about that.
Your apology was not what I am after and wasn't necessary.
I am sorry that I don't have time and knowledge to give you better answer.

Don't know if pancake still checks the forums but...
There's no k4 stone yet in this game, but take a look at how Lee Sedol handles the nobi after the peep:
