Oh, wow, that was topazg's plan ... and here I thought he wanted to fight! :D I'll probably jump next, as shown below, but I'll think about it first.

It'll be interesting to find out how exactly topazg plans to defend here. The marked Black stone is in big trouble.

Needless to say, this would be a fantastic result for White. However, if Black were to prevent this variation, White could capture the lone Black stone. The following move should work, although there could be other (greedier) ones, as well. This would be a loss of around 20-25 points for Black (although Black did get around 7 points on the right side). Thus, Black would likely fall further behind.

That said, I have a feeling topazg's whole plan is to sacrifice this one stone in exchange for profit on the top-right. Thus, I'll need to think some more. Maybe I can come up with something cleverer.
Edit:
In retrospect, why not try to capture the Black stone right away any be done with it? :roll:

In retrospect, maybe I should have played at O13 instead of P13. Now, the cut at O14 might remain a problem for a long time.

As for the aji of R12 which I was looking at in my previous post, I can't make anything work there, yet. Also, I was incorrect in thinking that I could kill the Black stone in the bottom-right via a shoulder attachment. I cannot see how to kill Black after the following variation:

Given this, it's better to encourage Black to jump instead, gaining White points along the side.

The idea behind this is to give some strength and eye-space to the Black weak group while preventing White from potentially linking up via a sequence such as below.

The drawback of Black's plan is, of course, that it solidifies White's corner (secure territory + few aji).

I am unlikely to deviate from the sequence I indicated above, but I'll double-check if there aren't any cleverer tries for White.

As I've been quite poor at keeping my thoughts posted due to limited time at the moment, I've put some of the random spare time I've had in the last couple of days writing my thoughts up a bit.

Any thoughts, questions or comments you want me to see are welcome :)

If I haned, I was worried that I'd give Black too many cuts, cross-cuts, and whatnot. This could let Black live too easily. The solid extension, by contrast, reduces Black's options and leaves Black with only one eye on the side, forcing a running battle. The following is a possible sequence:

The order of moves is important.
For instance, if hane first, Black could choose this variation, essentially guaranteeing life to the Black group.

That looks like a White mistake to me... life is now guaranteed locally, which is handy!

I don't see it as possible for White to prevent Black getting an eye at "a" and another at "b", which means I'll probably think about playing :b73: around "c"

Change of plans. :) There probably isn't much substantive difference between the moves, hopefully, but I better check.

I guess topazg could try to live here--but only at the cost of harming the two Black stones above. The price for life might be too steep. Naturally, he might simply jump, leaving the aji in the position for when he truly needs it.

Black threatens to connect, as the cutting stone at :w6: has nowhere to run and, thus, would get captured in short order (and, besides, Black would already be alive on both sides even if :w6: were to survive).

However, I think I can simply extend downward. This move not only prevents the connection, but also threatens to cut off Black's two stones from the stones above them.

To be honest, I am a bit surprised that topazg has, so far, refused so strongly and sternly to jump and fight. I surmise that he worries about giving me too much territory along the bottom, but living small (like he seems intent on doing)--and at the expense of the other stones on the right side--might turn out to be a significantly worse choice. Well, we'll see.
