Note in your variation you played hane with 77 at 78: that doesn't work as white cuts. I hope you can see that just extending is BRILLIANT for black. What is white achieving with this crawling? Trying to win five-in-row?
Something to note is your n4 q4 stones are weak and vulnerable because you missed the hugely important separation at s5 for move 19 so getting them connected and strong like this whilst white crawls along the 1st line is great for you. That 1st line move is an underplay for white and he could do much more severe things like L3 invasion to attack n4 and maybe even g3 cut later or h3 peep.
Oh... yes, I start to understand where the problem is...
so back to the original game 1 :

I was thinking

was good move as it secured territory in the bottom... more and more I understand

secured... pretty much nothing
I mean I played

thinking it was sente as white needed to reply with D2, what he did. But then what... If I want to secure territory in the bottom, I still need to fix the other side with something like

which is gote I think... but my opponenent replyed with that

so that I can keep sente... but what if he played at

at "a" ? Then that would be a very different game.... And sure, even after

, there are still good ways to reduce that bottom like you suggested for example with that peep at "b"...
So given all that, I understand

is very questionable...
and that tenuki would have been bigger here as once again,

didn't secure the whole bottom... (if that was the case, I assume that it would be a good move, but not in this case)
