I'm fairly sure that none of the above work, and I wanted to take all my sente in the lower right corner and then monkey jump up the right hand side for lots of reductiony points. If that worked for me, and I was right that none of the above were effective, the game would be completely over. However, I'm ahead, and this is an endgame move I want anyway. So, what could he have done / still do?

This looks really bad for White. I don't think I can let him cut here without serious dangers to my health. So, instead, I block the other side:

This now reverts to the previous diagrams, as it is aiming at the same bad aji. Again, as long as I block at 168 I'm ok. The other "b"?

Also aiming at the same cut (with "a") as the previous variations, this one has some tricksy local followups too. I was already wondering how much I'd have to be careful if he attached on top of my stone here, so this kind of position has increased its threat value. I can't see anything that obviously works, but that middle is a lot of points for me, and I don't want him taking them away. There's a lesson in winning won games somewhere. Adding the stone I just played kills that aji completely. What about "c"?

Well, he obviously wants life, but there aren't two eyes there to make. I'm not going to go into the myriad of possible variations, but the amount of thickness I have outside means that there are plenty of pushes, cuts, eye-steals and peeps. I may try to keep him down to 0 eyes, but the fact I don't have to makes the kill very likely I think.
So, I can't see anything in any of these, and instead I've chosen to play here to get my sente ball rolling. If he connects solidly, I tenuki:

Otherwise, if he tries to keep the aji up with a hane, force him to connect first. I could play as follows to patch up the aji completely, but it's gote, and I think he has nothing to work with here now:
