In those pro games the extension stone is strong due to white positions just beyond it (so invading would not be attacking it) wheras in your game it has no support and just that looming black position beyond.

Yes, you are right, that is a difference.

Let us have a look at some variations with ELF next:

ELF prefers tenuki over a local play, but not by much:

Variation a:

This seems to be whites strongest response:

(Black has to tenuki in this position, to prevent the white tigermouth would be too small)

alternative variations without the press lead to similar winrates:

one example (I reviewed quite a few more):

Perhaps you like to suggest a different variation that demonstrates a more pronounced advantage of not pressing at O4.

Like I said I agree that the press is not one of the "best" options, but I think it is still a very reasonable choice if one aims to simplify the position (like I always do when I think I have the advantage). But perhaps I am wrong, I definitly consider your critique.

And two more pro games with more "extreme" positions:

Or it is kind of magical thinking by me:

Here's a few ideas, I didn't check with bots but those >90% elf winrates show why I prefer LZ once the game is this lopsided to more easily see subsequent mistakes.

Build corner and side in sente. Let white get strong too.
