Black's desire to cut white apart here is a good one. I feel white's last move is dubious.
If black can follow up with a move like :b2:

and kill white's reduction stones, then he has a won game.

It's actually a bit complicated, and I don't fully trust the correctness of my reading here, but it looks to me like black can (barely) make this cut work. The waist cut :w5:

makes things messy, but I think black can fall back at :b6:

and keep everything intact.

If black can make this cut as above, then by my estimation black is at least 20 points ahead, so black can also probably win with a gentler play that doesn't attempt to cut off white completely, especially if the above variations are too complicated or if they in fact don't work.

my concern here is with the top group making life

it a great move but then i saw the double knights move again!

the double knights move is perfect for making life and connecting to the outside.

i wonder what he is going to do now maybe, push out into the center

seems simple enough but he might try something funny
im just glad i found it, after i played it out a few times it seems like the perfect move, its way better than my previous post *pat myself on the back*

but the basic principle behind pivots points is blocking off your oppponent from jumping in your moyo, finding the place to build walls to block off territory like in this situation.

Yes, it does. But it also gives black some terrible shape. The resulting aji left due to black's bad shape is very interesting. I think white should be able to get some compensation because of it.

White can first threaten a squeeze with :w1:

Black cannot cut yet.

So black defends. I think :b2:

is the best way - if black tries other things, white gets additional forcing moves around 'a', which helps white a lot in some of the upcoming variations. Then white connects at :w3:

, damaging the marked black stone, and if black wants to cut with :b4:

, he can only do so with another bad shape.

From here, I don't know exactly what white can do with the resulting position, but here are some variations.

White could try a cut and sacrifice first, and then :w7:

looks fun.

If black resists, he gets into trouble as white breaks into the center in a much bigger way. :w6:

is a nice way to connect back in sente, threatening ko-snapback, and also white has the wedge at 'a'.

If black varies on the top but isn't careful enough, he might die on the top left in this sort of variation.

Maybe black has better resistance, but I think white should be able to get something starting with :w1:

and then in a lot of the resulting variations, the push at 'a' and the wedge at 'b' and maybe the peep at 'c' become very useful resources.
