Strategy and Thoughts
Hmm, so I lied. White actually has a large central moyo going on right now, which made my move an invasion instead of a reduction. A really deep invasion, actually. Which isn't what I want at all, so that last move was a mistake. And it also means my count was probably off.
So I need to rethink things. As is, I can treat this as a forcing move and see if I can think of a better place to play.

Black: Top Left: 10 Top Right: 50 Bottom Left: 15 Bottom Right: 5 Total: 80
So the fact that the left moyo really does cover a large area of the center, and white has started closing it off now, means I'm not in a good position. So I'm behind enough that an invasion really is necessary, probably. Anyway, let's consider different options below:
Tactics and Variations Part A
Okay, so let's see what happens if I stick with the plan of making a reduction. I can treat the move I just played as a forcing move and just leave it (it's not a very good forcing move, but what's done is done).

And then count the score to see if it's enough:
Black: Bottom left: 20 Top left: 10 Top Right: 50 Bottom Right: 5 Total: 85
White: Right side: 25 Bottom: 10 Left side: 55 Komi: 5 Total: 95
...
So yeah, that's within 10 points so the game would still be somewhat close. So it's not an unreasonable line of play. Whoever has the stronger end game would probably win. I tend to have a pretty good endgame, though since white is several stones stronger I'm not sure if I can really rely on it. So eh, let's see what else there is.
Tactics and Variations Part B
What if I use the momentum of my stone and continue the invasion? I should expect to end in gote, hopefully either connected out or with life. But then white can take sente to take the large move on the bottom.
This sequence isn't optimal at all, and actually if it went like this I think I'd still get sente out of it somehow, but if we assume that the invasion will have to end in gote, and we just want an idea of the resulting score:

It looks like white actually gets sente after this sequence on the bottom, though. So maybe it's really reverse sente for me instead of gote.
Black: Bottom Left: 15 Bottom Right: 5 Top Left: 10 Top Right: 50 Total: 80
So actually that's the same spread as the reduction. I guess that tells you how huge the bottom move is. And actually, it looks like white can make the bottom move in sente...
Tactics and Variations Part C
Working on that last diagram, I realize that the move on the bottom might be reverse sente. Which makes it way larger than I thought at first. Easily the largest point on the board, even with white's moyo. So what if I go for it first? What can white do? His moyo, at least the center part of it, still has two open borders I could reduce against.

Black: Bottom Left: 20 Bottom Right: 5 Top Left: 10 Top Right: 50 Total: 85
So yeah, there's some fudge here definitely, but this is a reasonable line of play, which will leave the score close.
Tactics and Variations: Conclusion
Wow, so actually, the end game move on the bottom is so big that getting it actually makes up for letting white have more points on the left side. Given that they're the same point-wise, I'm going to opt for the line of play that is the least risky. Or at least, I think I've read it out well enough that I can predict that white will just pull back. If I screwed this up and white can capture it, I'm in some deep trouble.
This is White's chance, I think. Even if Black's reduction was a mistake (which I am not convinced of), it can't be allowed to simply die like this. Black should make something out of it, at the very minimum something like this:

In no way can Black simply "treat that stone as a forcing move". That's fear talking. Forcing moves should be exchanges that benefit you, and shouldn't be rendered completely meaningless (in fact giving White huge territory) if you tenuki. Now I think White can play something like this and suddenly make this game much closer:

Edit:
I just took a look Num's variations in more detail and I think he doesn't realize how big of a threat that Black stone is if it can escape clean. White can't take sente in this variation:

Something like this can destroy the entire left, and I don't even think my variation is the most vicous:

Okay white, that wasn't a bluff, so let's hope for your sake you just read better and black 69 was an overplay.
If I manage to make these stones live every point of territory I make is worth like 4 points (1 point for territory, 1 point for robbing territory, 1 point for black stones on top of what was once white territory, one point for white stones on top of what was once white territory). The game was close enough if white drew back that it was still playable for either side. This seems like a move of desperation, but a desperation play isn't necessarily backed up by the score. If my stones live here, it goes from close to white at a distinct disadvantage/outright losing. On the other hand, if I lose these stones, I'm out lots of points but I should end in sente (die in sente) and should be able to make up many of the points elsewhere. I'll be losing on the board but it should be outright terminal mistake time.
...
Okay, so I have to do some really serious reading to find a reasonable sequence. I feel like I should be able to live, and white will get thickness facing the center. Thickness won't be worth very much since there's nothing there to attack and it doesn't really close the open boundaries of the moyo. Good for black.
Tactics and Variations
This is the sort of sequence, where white just descends, that I need to spend some time thinking about.

Stealing the descent (the opponent's good move may be my good move) gets complicated really fast, since it allows for kos and sacrifice tactics for either side.

Strategy and Thoughts
Bottom line: one way or another, white is screwed. I think. Grr reading.
Tactics and Variations
I don't see how white can prevent either life or connecting out for black's group. There are too many variations to list them all, but here's what I consider to be the "main" line:

'a' and 'b' become miai for either connecting out or making life, respectively.

There are some other choices for moves further up the chain (different choice for two in the first diagram), but they're either easy to refute or actually end in sente for black, which probably isn't what white is aiming for. I wouldn't mind something like this, certainly (notice I get to play 5 as a tenuki). Although if it actually goes this way I might see if I can't find a better sequence. But I doubt white will play this way.

I am not going to give him more 4th line territory. He is creating a group to easily run to. His aims must be to reduce my left side more. We'll see where he goes next

Strategy and Thoughts
White is getting in to the annoying habit of making moves I specifically don't think he will.
Tactics and Variations
This is the best sequence I can see. Increase the sacrifice (increase the liberty count of the stones to be sacrificed) so I can make extra moves on the outside. And I get sente out of the whole thing. cha-ching.

The '3' stone above really aggressively destroys white's moyo. The ladder doesn't work for white, so I don't think I even need to defend right away. Tenuki and take sente.

Strategy and Thoughts
Oops, I don't think I thought about this possibility at all.
I think I can still sacrifice, but I have to give white more of the side territory. I might also be able to treat the entire side lightly and use some threats to dig in to the territory on the bottom right. I might also be able to just make a fight of it and save the stones I was going to sacrifice, but I need to check to see if doing so is actually a good idea (ie: does what white gains in the center more than make up for it?)
Tactics and Variations A
Let's examine the most exciting possibility: can I save the stones?
Below: While 1 steals a liberty from white and gives a liberty to black, 2 does the same back, and black can't squirm effectively enough to gain enough liberties to capture. So the stones are still definitely dead (unless there's a tesuji I don't see).

So something like this instead, maybe. White gets a lot of the side, and has prospects for more because of the open skirt, but I have sente so I can decide whether I want to defend with something like 'a' or if I want to do something in the middle. There's less aji for either side this way then in the first diagram I gave, so I'm going to go this way (keeps the game simpler). This is giving up a lot of the territory I wanted, but I guess the attachment I did originally was an overplay. Sort of frustrating really. But I knew going in to this game that these sorts of tactical gaffs would lose me points.

Tactics and Variations C
Can I be super sneaky with my play and try something he won't be expecting? Like invading on the other side now?
Something like this seems to work to get black enough liberties to capture white on the left, so it seems promising so far.

So I'm going to conclude that maybe there's something that could be done here, but it's way out of my depth.
Tactics and Variations Conclusion
I'm going to stick with the strategy of using the stones as a sacrifice to secure the side boundary and gain some center influence to limit white's moyo there.

Changed my mind. If he wants to score the 12ish points on the bottom in gote he can have them. I'm not going to give up initiative to get them at this point. This would be horrible for him:

Strategy and Thoughts
Hrmm...
One of three possibilities:
1. White made a reading mistake and doesn't realize I can capture his two white stones. 2. I've made a reading mistake and this will end horribly for me when I try to capture. 3. White has decided that his top moyo is worth more points than the paltry bottom territory.
Although I'd like to give white more credit, I think #1 is the most likely. If white wanted sente, he could have just withdrawn when I first attached. It would have amounted to about the same thing.
...
Anyway, I have a good move in mind. Combine ruining white's moyo a bit with saving my two stones and capturing white's.

This is what I'm thinking:

Notice that this threatens to save the two black stones, so if white ignores, 'a' and 'b' are miai for saving the two black stones. Which means it's entirely acceptable for white just to take sente again. White can reinforce his moyo, or whatever else he wants to do. But this is definitely the largest move for me. (I say without actually counting).

i am thinking they both miss the real point of this game. whomever gets the sente and going to the middle will win this game. i dont know exactly how to solidify the middle...but below seems to be one of the option.

@Numsgil
Have you tried counting?
Not since I last showed it. I'll do a count before the next move or two. But I did a count when I first started the sequence on the bottom, and I didn't think things had changed enough for the largest move on the board to have changed. Though white might get two moves in a row to secure his moyo, so maybe that was a mistake, dunno.
