I expected EdLee to solidly protect the other cut. In fact, I believe that playing that way would have been better. I think EdLee worried that I would be able to reduce his territory on top in sente like so:

However, "a" would no longer be sente for Black plus White would be able to reduce Black's corner in sente, gaining territory for himself on the left side:

Black has to play else "a" leads to a ko in the corner. Thus, White's loss on top in sente would be offset by Black's loss in the corner in sente. However, compared to the game, the above diagram would let White have much more territory on the left.
Anyhow, I think I was ahead even before White's last move. Therefore, I think that now I am definitely leading in the game. However, I need to be careful not to let White get too much territory in the center.

One feeling is the double hane.

Do you mean the following diagram is not jeseki in general or that it is not joseki only when Black has a double-wing formation?
With the night's move instead of hane, black (with 4-4)
1. has better endgame moves later 2. is little bit thicker then the hane variation 3. can consider tenuki

The hane variation still gets played, though, doesn't it? For example, Lee Sedol (as White) played it (and won) against Cho U in the 1st Round of the 13th LG Cup (2008):
Was the hane variation a good choice in this case because of how far the marked White stones are?

3-3 invasion is rare when the extention from 4-4 is that far away. Well, since it's happened, and white can't expect something lot from extra thickness or tenukiing. I think Lee didn't want to give Cho an extra point from the night's move variation. Still, hane variation is no more played in usual cases, and joseki evaluation are done locally not considering the whole board position, which means something non-joseki can always be played in special situations.

It looks like EdLee was afraid of an invasion. I actually was not planning to invade. Anyway, I'll need to think about my move a bit. Perhaps I can try something like this:

I had a hard look at the position. It occurred to me that I was too dismissive of White's options in the bottom-left quarter of the board. Yet, White has surprisingly resilient invasions at the 3-4 and 3-2 points. As a result, I kept giving myself too many points there.
Thus, I came to the conclusion that I am, in fact, behind, currently. Thankfully, I like defending worse positions--at least in chess --so I expect no less from myself in Go.

I didn't explain the reasoning behind my last move. When I thought that I was ahead, my plan was to simply make a shimari in the bottom-left corner. However, now that I think I'm behind, my play has to be riskier. I'll need to read here a bit, but I hope to generate some kind of a splitting attack against the invading 4-4 stone and against White's stone on the left side. Otherwise, White's position is quite secure everywhere, so reversing the game by other means would be difficult.

This move is a bit of a gamble on my part. If I attacked from the outside right away, White would build a wall facing the bottom--which has more open space than does the left side--and live relatively easily from there.
With this in mind, my hope is to force White to try to live (or run) along the left side. Essentially, I am gambling that EdLee will next respond at or "a," upon which I can attack from the outside more severely. A significant advantage to forcing White to try to live on the left side is that I can hope to more easily generate an attack against the lone White stone on the left side.
The problem with my move, though, is that White does not need the invasion to live. Instead, White may use the invasion to reduce Black's moyo in sente while building his own large territory in the middle. White could play something like this, for instance:

White's profit in the center would leave White with a hefty lead.
As a parenthetical remark, I'd like to note how different chess and Go are when it comes to defending worse positions. In chess, the best strategy is usually to go into "deep defense" mode (by building a fortress, for example). In Go, such a patient approach is rarely the appropriate choice (unless, of course, one plays the endgame as well as Lee Changho does). I quite like the "deep defense" approach of chess, but Go's active-initiation-of-complications-when-worse strategy is quite exciting, too.

An immediate response--and the one I wanted to see. This lets me proceed with my plan. Sweet!
Objectively speaking, EdLee will likely need to make a mistake or two for me to reverse the game, but making a mistake won't be too hard in the complications to come. Next, I'll try to calculate more thoroughly which move on the outside will be the severest (I am leaning toward a diadiageima jump, as I've indicated in my previous post).

White's stone at J7 provides good support for White's invasion in the bottom-left corner. Because of this, although I would have preferred to play at "a," I made the diadiageima extension so as to make sure White has no easy way to connect his stones. The drawback of this, of course, is that the jump leaves behind weaknesses at points marked "b."

Next, White will likely try to exploit these weaknesses to settle his group. However, doing so is not easy. For instance, the following would be an ideal continuation for me.
else "a" leads to a ko in the corner. Thus, White's loss on top in sente would be offset by Black's loss in the corner in sente. However, compared to the game, the above diagram would let White have much more territory on the left.
--so I expect no less from myself in Go.
. 
or "a," upon which I can attack from the outside more severely. A significant advantage to forcing White to try to live on the left side is that I can hope to more easily generate an attack against the lone White stone on the left side.
