Life In 19x19

Yeah, I don't see how Celebrir could consider that trade and then reject if as good for black, it looks great for white to me. Black only gets 10 points in the middle, and white gets at least than from killing k17. But on top of that white gets very thick with loads of centre potential.

I guess this is an easy one. This seems to be key point between our moyos now. If I play elsewere this looks big for him:

Trying to see if I can make anything above the third line on the left side. I considered playing the second-line kosumi first, but white probably won't respond.

I think this a important move. Therefore I'll (try to) think carefully.

First a try to count (Counting is one of my weak points):

Black:
Bottom: 32
Left: 10
Upper right: 24
66 total
+potential at the left middle (15)

White:
Upper left: 16
Bottom left: 12
Right middle: 26
6,5 komi
1 prisoner
61,5 total
+potential at the right (7)

If this is correct his lead is not that big as I thought, but the big problem is his potential at the left. Best would be if I can reduce it in sente and move at the right afterwards.

is a calm move which aims at 'a'. defends but with the sequence up to This looks like a good reduction, but there is a weakness at 'b'. Maybe I can make some points at 'c' later.

I don't know how he'll continue, but with the peaceful answer this seems playable. I have some move to reduce the left now as well.

If he should try to fight I think I can be confident. Note that the exchange of the two circled stones helps me here.

I want to decide between Dia. 1 and Dia. 3/4. I think they're more or less equal but Dia. 3/4 is more complicate. Since I'm behind I want a more complicate game so I'll choose this move.

That is either the perfect reduction or too deep. I didn't read too carefully (6 am, and I need to do a case write-up before 9 XD), but suspect there's a keima cut potential after I exchange this for an extend. I don't think I have any better local moves other than this, so I'll just play it first. The biggest danger is perhaps white tenuki and play another move to try to attack my top centre group, but I think it's strong enough.

I don't think I have much options here. Instead of speculating about his next move now, I'll first post my move, hoping he answers soon and thinkimg about continuations later. Normally I wouldn't do that but like I wrote, I think I really have no other options here.

I also considered a kosumi, but in either case I think white will just run out the other way and I think this cut ends in a better shape. I guess white will run out, but I should keep sente and also will have some weaknesses around the resulting connection.

p.s. this is now 7 am - my powers of procrastination truly knows no bounds XD

Obvious reading mistake by me... I don't think the hane's work anymore, so I'll have to do something else. I'm aiming for the other direction now and think this can become quite dangerous for him.

Correct order of forcing moves might be different, this is only to show one idea. In all variations I see I'll either get out at the top or to the bottom. I hope I don't miss a variation again...

More promising for Black?

Mmmm, last time I thought there was something that makes this move (well, actually, I thought white would either G12 or kosumi, but G12 would probably transpose into this one) difficult. But now it seems like I actually can play this move without much danger. If I can play this, then white's last move probably should have been the kosumi.

If I read correctly he has two possibilities if he doesn't want to give me a ponnuki:
