The solid connection is the only possibility. Playing the tiger's mouth one point to the left allows him to trap the M4 group.
I'm curious: what would have happened if B played O4 instead of the solid connection?
Seems like a very legitimate question to me. I had missed that move, but I cant seem to find anything wrong with it. It seems to me even better than the game continuation, though that also looks to me like magicwand merely destroyed his aji with the bottom sequence. If there is anything wrong with that move, I would like to see it, too.

But the hane at M9 is very strong.
Any time he plays N5, I must reply with N4.

The cut? I thought that the clamp was his best play. I was prepared to concede him some territory just to maintain superior influence for the coming dispute in the upper right.

So what evil scheme is he hatching now? My reflex is to extend, but I must do some reading just in case the atari is better.

I think that I know. It looks like this:

White cuts with 1, black extends with 2;
White stands up with 3...

...black, fearing that white might trap him against the side by playing the circled point, develops at 4.

It looks good for black. If white extends at O5, black defends at O4. White cannot escape.

But white has an evil trap.

He threatens to escape with 1. Black defends at 2.
White ataris with 3, black defends again with 4.

Here is the move that I almost missed. Insead of playing O5, white plays O4.
Black must capture at O5 or lose his L4 group when white plays O5 himself.

I'm not sure that Joaz's line actually works for White. By 1-2-3 reading (I think this is how it's applied), Black should look at playing at O3 first, and this seems to save things:

(If White plays :w3: anywhere else, Black captures there immediately and connects everything.)

By making the M3-L4 exchange in Joaz's second diagram, White has also given himself a shortage of liberties, no?

Even with a generous count, the most my opponent has is 25 points. I have around 45 or 50 points. The focus soon will shift to the upper and right sides, where I have a huge lead in influence. It will some spectacular play by him to just break even on territory in those areas.

To have any chance at winning, he needs a fight, and it must go his way. Playing normal moves won't work for him.

So I'm playing safe moves, intending to quickly kill any stones that might disrupt the status quo.

Unfortunately, that variation does not give me enough points to overcome the current deficit because of losing sente and hurting my corner (ko).
i had no choice because it is still better than giving him everything. :(

It may be a while before I reply. Western civilization requires saving once again, and then Mrs. Banbeck and I are taking a short vacation for the Labor Day weekend, and then I have to sit and think about this for a while.
Western civilization is over-rated. The real problem here is that MW has written two hidden posts. I know from experience watching his games against other people that he writes a lot when he thinks that he is doing well, and little or nothing when he thinks that he is losing. I think that I'm winning, needing only to beat back one last desperate sneaky attack - but he posts TWICE, as if he thinks that he is winning.

So I have to look at this all over again, Mark Twain style. ( "It ain't what you don't know that gets you into trouble. It's what you know for sure that just ain't so.")

@magicwand:
What was "b" supposed to be in your first diagram?
@observers
I'm guessing "b" is meant to be M3, and magicwand is imagining a sequence like:

Notice that this line isn't nearly as effective if Black already has O3 in place, which is why I still think it's the vital point:

After much reading, I am dismayed to conclude that I must give up something. This move minimizes the loss.
