Now the fight starts. I hope to get some strength to reduce the left. I'm not sure about the continuation, but everything I read out is okay for me. The worst I find is this:

Aiming for a in the future. I'll happily exchange some of the top for some outside thickness here. I've played for influence on the left so a wall facing down is nice I think. I know things are a bit strange with me going for territory on the right but 4 stone is weird and I'm pursuing a strategy of two solid corners + moyo. I've no idea if this works or not.

That's not thickness. The four stones aren't 100% heavy, but they're not thick. White can't yet play at c or d, until he addresses the two black cutting stones, but once he does, he can play against those three black stones.

Again not much to say. This seems to be quite a forced move.

This is a little trick to make things more complex. I don't want to play the atari to conect my stones because it gives me less possibilities but I still want to protect the cut. This move does that:

Very unsure about this move, but I think it's forcing and I think it strengthens me on the left.

How is it forcing? Could you show your variations. :)

Yes... how does this make :b24: forcing? (In other words, for :b24: to be forcing,
W has to suffer some huge damage after :w25: tenuki -- could you show the damage?)

Hmm, I thought it was just damage not huge damage. If it's huge damage it's not forcing as White can afford to give up those two stones to secure the rest of the top.

I think I have to take the trade. It's a poor trade for me, I see that now but I'm unsure if I could have saved those cutting stones anyway. Perhaps I should have tried to though.

That's what "forcing" means -- that W MUST reply. If W does not have to reply, then how is it "forcing" ? :)
For Boidhre, but after this fight is finished,
Besides, W does not have to give up anything, because W (b) is sente -- from your post about (a) and (b) being miai:

You're quite correct Ed, I'm exactly sure what I was thinking! :)

Here's another way to think about it: every of your :black: moves, unless you're killing yourself like self-atari, or filling in a neutral point (pass),
as long as it's taking even 0.5 points of territory on the board, it's doing "some" damage to :white: --
if this were the entire meaning of "forcing," then practically every :black: move would be forcing.
Clearly, this is not the case.
"Forcing" means your opponent MUST reply, or Game Over for him -- this is the only possible meaning.

Having said that, just because a move is forcing does not necessarily mean it's good!
It can be a BAD forcing move -- yes, your opponent must reply, but he is happy to do it! --
because the result hurts you or helps him!
Distinguishing good sente moves from bad ones is another very deep topic. :mrgreen:
