...grudgingly. It gives white the option to sack his tail like this. I'm not sure how I feel about this. I don't think I would play this way, but it might be OK, esp. if we do something worthwhile with our sente.

Sometimes, simplest really is best. We could try to do something trickier, but most things that try to connect in sente seem to either not work, or force black to strengthen themselves, which isn't worth the cost. Let's stick to the simple, safe, and correct.

The last three moves strengthened two of our groups and only slightly improved black's iffy connection. That black group in the middle is looking like swiss cheese.
Simple is best, overcomplicated defenses, while sometimes correct, are more often just inflexible... Playing a simple defense often offers the most chances to counterattack.

Okay, so my first, second, and third thought was P14. However, while that is the only other move that seems to defend both cutting points adequately, it has downsides. In exchange for defending SLIGHTLY more eyespace around O14 if we also later block at P15 in gote, black could almost seal our group in from the bottom in sente, with peeps and such. This gives us much better access to the bottom (which also preserves more threat against the black group), so I choose it.

I'd been thinking this is going too well for black...
Can I save the top black group in sente?
First, it lives on its own if J19 is, as I suppose, forcing:

With black has two eyes guaranteed, I'm quite confident. But does it force ? If it does, fab: I can tenuki to rescue the center group. But if it doesn't, I might as well do this:

But the first option at least has a chance of being sente, is more interesting and is also, I expect, less damaging to my four-wind-sheeted center grouplet.
in my continuation may be O12, or something else, and keep the wedge for later. I'll look at it closer after the next move.
? If it does, fab: I can tenuki to rescue the center group. But if it doesn't, I might as well do this:
