Sorry to disappoint you, but this stage never really goes away:
even pros encounter situations where they are not sure what's the biggest move.

Some general advice, if such is allowed, is that with the o3 approach you declared that area was biggest. Perhaps that was right, perhaps it was wrong. But at least you next moves should be consistent with your past moves, so unless it is already a good exchange or you can come up with some coherent idea of why that approach was a probe to help you decide between different choices elsewhere you should do something with your last move. A bad plan is better than no plan at all, as they say.

I'm expecting black to finish the joseki, otherwise I get to push out, which will make black's position a little unhappy. After that, what shall I do? Hmm. I'm thinking the right-hand side or the upper right is the right place to look at next.

Note: Playing this joseki is weird when in a Malk game. Had to do it a few times before I got the stone where I wanted it lol. Silly me.

But to comment on the game, interesting position. Not sure how I feel about it. The top left was not ideal. I like the top right for Black. But maybe playing like that screwed me over.

I think getting the favorable result in this game will depend on whether or not I can diminish the left side for W, gain central control, and ease the weakness on the right. Not necessarily in this order, of course.

I've had my eye on this for a little while, and a split on the right seems natural after the lower right sequence. It might actually be a little too early for this, but I'll play it now as a probe. (I'm not too worried about a fight: my upper group can secure itself with Q17 right now, and playing K18 would work too, but is a bit of a crappy emergency move.) I think this stone asks a useful question: which bit of the right-hand side does my opponent want to keep, and how will he defend it? Let's see whether I'm right.
